Before puck drop on the conference finals… group chat wellness check? Especially the Oilers and Maple Leafs. I don’t think there are any Bruins in the gc but watching them hug Bergeron as they left the ice was rough

YOU COME HERE? INTO MY HOUSE BLOG and ask me about the FEELINGS OF THE BRUINS????

No fr fr tho I did see that handshake line and it was very sad.

BUT a wellness check... and a couple of lil spoilers for upcoming gc

Gabe's in surgery - he's recovering, poor Baberiel.

EJ's down in Cali with Paul, holed up and trying not to think about the future.

JT is feeling like the WORLDS WORST CAPTAIN because obviously if he were a BETTER CAPTAIN the leafs would have made it further (he's wrong. It wasn't on him)

Freddie is stressed. Because he NEEDS to prove that he can make it in the postseason but he's not getting as many starts as he WANTS, but also he's won way more games than he's lost. So overall. He's ok

Auston is in carolina, hiding in Fred's apartment. Being his biggest cheerleader and being secretly grateful that they never had to play 5OT

Jacky is mourning the loss of his tooth. Also playoffs are HARD why did nobody tell him that playoff hockey was hard? I mean, obviously he figured it out pretty quickly, but yeah, that's so fucking different to regular season hockey... why did nobody mention it? (spoiler alert, they did)

JSoup is very happy about Jacky's lil tooth gap which he thinks is the cutest thing ever. He lowkey doesn't care about not making it any further because honestly, he wasn't getting the starts and he wasn't expecting the starts and he never knows where he's gonna be, maybe it'll be a cup contender, maybe it won't, he's just along for the ride.

Leon and Connor are fighting, because one of them thinks that they should head down to Florida to support Matthew even though they've only just been kicked out of the playoffs themselves, and the other one thinks they should give themselves a couple of weeks together to lick their metaphorical wounds and just be with each other. It is not the way round we expect.

Jeff is cheering on Carolina like he's never cheered any team on before and if you ask him he'll say it's just because they're his old teammates but truly it's because he just wants the panthers to lose...

Sid and Nate had a brief moment of "should we just go to worlds?" and then decided they were far too old and are on holiday in the sunshine working on their golf

Dylan and Alex are in Toronto chilling with the fam and generally enjoying the off season

Tyler is playing his lil socks off

Matthew is....... Matthew is pretty convinced he's walking around in a dream because none of this actually feels REAL right now. Oh, and also he learnt to advocate for himself a little bit, with some help from his boyfriend

Ritter - is in florida, enjoying "the sun" ;)

Willy and Latts are holed up in their cabin

Jeff and Richie are holed up in THEIR cabin

Danny and Claude would LOVE to be holed up in the cabin, except, well... there are children to look after and they're working hard to give Ryanne a break

Cale is... struggling. Because OK he could feel the team was different from last year but, but, they were the fucking reigning champs, and they lost? In the first round? And he needs to TALK about it, but... he doesn't feel he can talk to Carter because, well, it's a bit shitty to COMPLAIN about losing IN THE PLAYOFFS to someone who's not MADE the playoffs for the past few years

Bobby Lu is having the time of his life

Kaner is sulking. This year did NOT go to plan. Also he's now a UFA... what's with that, he could play ANYWHERE? That's not how hockey's supposed to work... he's a hockey GOD... he's supposed to STILL BE IN THE PLAYOFFS and also he'd very much like to stay in NY please, but he doesn't think that's likely to happen and he really REALLY wants to blame Vladi Tarasenko, if only the fucker wasn't so nice....

Jonny is... dealing with Sulky Peeks. And Baby Pat. And he's still sick, because chronic illness doesn't just Go Away and he's having to make tough decisions and if Peeks could stop trying to make himself the centre of the universe for just one minute... you'd think he'd be used to that by now

Key is having Big Confusing Feelings... nothing new there then. He's in his research era. We stan a man with footnotes.

HTML Parsing in FLUTTER for Android / iOS Development

The HTML parser is the structured markup processing tool defining the HTML Parser class. It is often accessed to parse HTML files. Parsing is to resolve into component parts and then describe their syntactic roles.

In general, parsing analyzes the String of the symbols in computer or natural languages. When speaking about HTML parsing, it takes the HTML code and extracts the relevant information, such as the page’s title, headings, paragraphs, links, bold text, and much more.

Keep reading this article to learn much about HTML parsing in Flutter for android or iOS platforms! If you need professional assistance, do not hesitate to contact the reputable and trustworthy Flutter app development company.

Introduction to flutter HTML

Flutter is an open-source, cross-platform mobile app development framework. It is highly compatible with the present web rendering technologies such as HTML, JavaScript, and CSS.

Therefore, it is a perfect platform for web and mobile app development. With the help of Flutter developers, you can compile the existing code into the client experience, implant it into the browser and finally deploy it to any web server.

When you build the application with Flutter and need to render some HTML content, you can do it easily by accessing the plugin flutter_html. You can add flutter_html and its latest version to the dependencies section in pubspec.yaml file using the command “flutter pub add flutter_html.” Then, you have to use “flutter pub get” to execute the command.

How to do HTML parsing in Flutter

Android developers use the Jsoup library to parse HTML text and code. But, developers new to the flutter mobile app development do not know the existence of such a library to parse HTML text and code from the website in Flutter.

So, are you thinking about the right way to perform HTML parsing in Flutter for Android or iOS development? Well! Here are the two different solutions to meet your demands.

Solution: 1

You can now parse the HTML string in this way.

import ‘package:html/parser.dart’;

//here goes the function

String _parseHtmlString(String htmlString) {

var document = parse(htmlString);

String parsedString = parse(document.body.text).documentElement.text;

return parsedString;

}

Solution: 2

Next, you have to fetch data using http.get(url) to the user parser, and then you can parse whatever you want. Follow the below-mentioned code properly.

Fetch HTML page:

Future<string> fetchHTML(String url) async {

final response = await http.get(url);

if (response.statusCode == 200)

return response.body;

else throw Exception(‘Failed’);

}</string>

After that, you should call FutureBuilder()

FutureBuilder< String>(

future: fetchHTML(‘http://your_page.ru/page.html'),

builder: (context, snapshot){

if (snapshot.hasData) {

//Your downloaded page

_temp = snapshot.data;

print(snapshot.data);

return Text(‘Finished’);

}

else if (snapshot.hasError)

return Text(‘ERROR’);

return Text(‘LOADING’);

},

),

Now, you can parse it:

parse(_temp);

Other ways to parse HTML in FlutterMethod: 1

Are you accessing Flutter? Do you wish to parse HTML using parser.dart? If yes, then run the following code.

<div class=”weather-item now”>

<span class=”time”>Now</span>

<div class=”temp”>19.8<span>℃</span>

<small>(23℃)</small>

</div>

<table>

<tbody><tr>

<th><i class=”icon01" aria-label=”true”></i></th>

<td>93%</td>

</tr>

<tr>

<th><i class=”icon02" aria-label=”true”></i></th>

<td>south 2.2km/h</td>

</tr>

<tr>

<th><i class=”icon03" aria-label=”true”></i></th>

<td>-</td>

</tr>

</tbody></table>

</div>

You may have to use the following command to get this data.

import ‘package:html/parser dart’;

output:

19.8,23,93%,south 2.2km/h

Method: 2

Since you access the HTML package, you can obtain the desired data by accessing some HTML parsing and string processing whenever needed. Here is the dart sample where you can utilize the parse data function in your flutter application.

main.dart

import ‘package:html/parser.dart’ show parse;

main(List<string> args) {

parseData();

}

parseData(){

var document = parse(“””

<div class=”weather-item now”>

<span class=”time”>Now</span>

<div class=”temp”>19.8<span>℃</span>

<small>(23℃)</small>

</div>

<table>

<tbody><tr>

<th><i class=”icon01" aria-label=”true”></i></th>

<td>93%</td>

</tr>

<tr>

<th><i class=”icon02" aria-label=”true”></i></th>

<td>south 2.2km/h</td>

</tr>

<tr>

<th><i class=”icon03" aria-label=”true”></i></th>

<td>-</td>

</tr>

</tbody></table>

</div>

“””);

//declaring a list of String to hold all the data.

List<string> data = []

data.add(document.getElementsByClassName(“time”)[0].innerHtml);

//declaring a variable for temp since you use it in multiple places

var temp = document.getElementsByClassName(“temp”)[0];

data.add(temp.innerHtml.substring(0, temp.innerHtml.indexOf(“<span>”)));

data.add(temp.getElementsByTagName(“small”)[0].innerHtml.replaceAll(RegExp(“[(|)|℃]”), “”));

//You can also do document.getElementsByTagName(“td”) but it is more specific here.

var rows = document.getElementsByTagName(“table”)[0].getElementsByTagName(“td”);

//Map element to its innerHtml,

because we’re gonna need it.

//Iterate over the table-data and then store it safely in the data list

rows.map((e) => e.innerHtml).forEach((element) {

if(element != “-”){

data.add(element);

}

});

//print the data to console.

print(data);

}</span></string></string>

Output

How to parse HTML tags in Flutter

Do you need to parse HTML tags in your flutter project? Well! You can follow the steps mentioned here to meet your needs instantly.

At first, you should create the flutter application.

Then, you must add the required plugins in pubspec.yaml file as mentioned below.

dev_dependencies:

flutter_test:

sdk: Flutter

html: ^0.15.0

http: ^0.13.3

flutter_html: ^2.1.0

Now, you have to read the HTML file from the URL. Once you mention the site, it reads the data online. Use the http:package to read the data you have accessed and get the http class.

var response=await http.Client().get(Uri.parse(widget.url));

Now, you have HTML data fetched from the URL by accessing the HTTP package. So, it is the right time to parse the fetched content. You can use the below code to parse the HTML tags.

var chapters = document.getElementsByClassName(“chapters”);

chapters.forEach((element) {

var inner = element.innerHtml.toString();

if (inner.contains(“href”)) {

parse(inner).getElementsByTagName(“li”).forEach((element) {

var list = element.innerHtml;

if (list.contains(“href”)) {

//

indexlist_local.add(list.substring(list.indexOf(“href=”)+6,list.indexOf(“>”)-1));

indexlist_local.add(IndexContent(title: element.text,

path: list.substring(

list.indexOf(“href=”) + 6, list.indexOf(“>”) — 1)));

}

});

}

});

This code is written for fetching the data from the indexed tutorial page “chapters.” According to the URL you choose, you can change the index tag.

Finally, you can run the application successfully.

Conclusion

So, you will now be aware of the HTML parsing in Flutter for android/iOS development. If you do not get the desired result even after trying all the possible ways, you should seek professional assistance. Hire Flutter developer to get assistance in HTML parsing and complete your flutter project without hassle.

How to Build a Web Scraping API using Java, Spring Boot, and Jsoup?

Overview

At 3i Data Scraping, we will create an API for scraping data from a couple of vehicle selling sites as well as extract the ads depending on vehicle models that we pass for an API. This type of API could be used from the UI as well as show different ads from various websites in one place.

Web Scraping

IntelliJ as IDE of option

Maven 3.0+ as a building tool

JDK 1.8+

Getting Started

Initially, we require to initialize the project using a spring initializer

It can be done by visiting http://start.spring.io/

Ensure to choose the given dependencies also:

Lombok: Java library, which makes a code cleaner as well as discards boilerplate codes.

Spring WEB: It is a product of the Spring community, with a focus on making document-driven web services.

After starting the project, we would be utilizing two-third party libraries JSOUP as well as Apache commons. The dependencies could be added in the pom.xml file.

<dependencies>     <dependency>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-web</artifactId>      </dependency>         <!-- https://mvnrepository.com/artifact/org.jsoup/jsoup -->      <dependency>         <groupId>org.jsoup</groupId>         <artifactId>jsoup</artifactId>         <version>1.13.1</version>      </dependency>        <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-lang3 -->      <dependency>         <groupId>org.apache.commons</groupId>         <artifactId>commons-lang3</artifactId>         <version>3.11</version>      </dependency>          <dependency>         <groupId>org.projectlombok</groupId>         <artifactId>lombok</artifactId>         <optional>true</optional>      </dependency>      <dependency>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-test</artifactId>         <scope>test</scope>      </dependency>   </dependencies>  

Analyze HTML to Extract Data

Before starting the implementation of API, we need to visit https://riyasewana.com/ and https://ikman.lk/ to locate data, which we need to extract from these sites.

We can perform that by launching the given sites on the browser as well as inspecting HTML code with Dev tools.

If you are using Chrome, just right-click on the page as well as choose inspect.

Its result will look like this:

After opening different websites we need to navigate through HTML for identifying a DOM where the ad list is positioned. These identified elements would be utilized in the spring boot project for getting relevant data.

From navigating through ikman.lk HTML, it’s easy to see a list of ads are positioned under a class name’s list — 3NxGO.

After that, we need to perform the same with Riyasewana.com where ad data is positioned under a div with id content.

After recognizing all the data, let’s create our API for scraping the data!!!.

Implementation

Initially, we need to define website URLs in the file called application.yml/application.properties

website:  urls: https://ikman.lk/en/ads/sri-lanka/vehicles?sort=relevance&buy_now=0&urgent=0&query=,https://riyasewana.com/search/

After that, create an easy model class for mapping data using HTML.

package com.scraper.api.model; import lombok.Data; @Data public class ResponseDTO {    String title;    String url; }

In the given code, we utilize Data annotation generation setters and getters for attributes.

After that, it’s time to create a service layer as well as scrape data from these websites.

package com.scraper.api.service; import com.scraper.api.model.ResponseDTO; import org.apache.commons.lang3.StringUtils; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Service; import java.io.IOException; import java.util.HashSet; import java.util.List; import java.util.Set; @Service public class ScraperServiceImpl implements ScraperService {    //Reading data from property file to a list    @Value("#{'${website.urls}'.split(',')}")    List<String> urls;    @Override    public Set<ResponseDTO> getVehicleByModel(String vehicleModel) {        //Using a set here to only store unique elements        Set<ResponseDTO> responseDTOS = new HashSet<>();        //Traversing through the urls        for (String url: urls) {            if (url.contains("ikman")) {                //method to extract data from Ikman.lk                extractDataFromIkman(responseDTOS, url + vehicleModel);            } else if (url.contains("riyasewana")) {               //method to extract Data from riyasewana.com                extractDataFromRiyasewana(responseDTOS, url + vehicleModel);            }        }        return responseDTOS;    }    private void extractDataFromRiyasewana(Set<ResponseDTO> responseDTOS, String url) {        try {            //loading the HTML to a Document Object            Document document = Jsoup.connect(url).get();            //Selecting the element which contains the ad list            Element element = document.getElementById("content");            //getting all the <a> tag elements inside the content div tag            Elements elements = element.getElementsByTag("a");           //traversing through the elements            for (Element ads: elements) {                ResponseDTO responseDTO = new ResponseDTO();                if (!StringUtils.isEmpty(ads.attr("title")) ) {                    //mapping data to the model class                    responseDTO.setTitle(ads.attr("title"));                    responseDTO.setUrl(ads.attr("href"));                }                if (responseDTO.getUrl() != null) responseDTOS.add(responseDTO);            }        } catch (IOException ex) {            ex.printStackTrace();        }    }    private void extractDataFromIkman(Set<ResponseDTO> responseDTOS, String url) {        try {            //loading the HTML to a Document Object            Document document = Jsoup.connect(url).get(); //Selecting the element which contains the ad list            Element element = document.getElementsByClass("list--3NxGO").first();            //getting all the <a> tag elements inside the list-       -3NxGO class            Elements elements = element.getElementsByTag("a");            for (Element ads: elements) {                ResponseDTO responseDTO = new ResponseDTO();                if (StringUtils.isNotEmpty(ads.attr("href"))) {                   //mapping data to our model class                    responseDTO.setTitle(ads.attr("title"));                    responseDTO.setUrl("https://ikman.lk"+ ads.attr("href"));                }                if (responseDTO.getUrl() != null) responseDTOS.add(responseDTO);            }        } catch (IOException ex) {            ex.printStackTrace();        }    } }

After writing the scraping logic for a service layer, we can now implement the RestController for fetching data from these websites.

package com.scraper.api.controller; import com.scraper.api.model.ResponseDTO; import com.scraper.api.service.ScraperService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import java.util.Set; @RestController @RequestMapping(path = "/") public class ScraperController {        @Autowired    ScraperService scraperService;    @GetMapping(path = "/{vehicleModel}")    public Set<ResponseDTO> getVehicleByModel(@PathVariable String vehicleModel) {        return  scraperService.getVehicleByModel(vehicleModel);    } }

When everything is completed. We need to Run this Project as well as a test this API!

Go to the RestClient as well as call API through offering a vehicle model.

For example http://localhost:8080/axio

Here, you can observe that you have all the ad URLs as well as titles associated to given vehicle models from both these websites.

Conclusion

In this blog, you have learned about how to manipulate the HTML document using jsoup as well as spring boot to extract data from these two websites. The next step will be:

Improving this API to help pagination in these websites.

Implementing the UI for consuming the API

Gabe's in surgery - he's recovering, poor Baberiel. EJ's down in Cali with Paul, holed up and trying not to think about the future. JT is feeling like the WORLDS WORST CAPTAIN because obviously if he were a BETTER CAPTAIN the leafs would have made it further (he's wrong. It wasn't on him) Mitchy is trying to convince his boyfriend that a. he doesn't carry an entire hockey team on his shoulders and b. He's not too old. They can win a cup together and the world won't fall apart without Spezz and Dubey Freddie is stressed. Because he NEEDS to prove that he can make it in the postseason but he's not getting as many starts as he WANTS, but also he's won way more games than he's lost. So overall. He's ok Auston is in carolina, hiding in Fred's apartment. Being his biggest cheerleader and being secretly grateful that they never had to play 5OT Jacky is mourning the loss of his tooth. Also playoffs are HARD why did nobody tell him that playoff hockey was hard? I mean, obviously he figured it out pretty quickly, but yeah, that's so fucking different to regular season hockey... why did nobody mention it? (spoiler alert, they did) JSoup is very happy about Jacky's lil tooth gap which he thinks is the cutest thing ever. He lowkey doesn't care about not making it any further because honestly, he wasn't getting the starts and he wasn't expecting the starts and he never knows where he's gonna be, maybe it'll be a cup contender, maybe it won't, he's just along for the ride. Leon and Connor are fighting, because one of them thinks that they should head down to Florida to support Matthew even though they've only just been kicked out of the playoffs themselves, and the other one thinks they should give themselves a couple of weeks together to lick their metaphorical wounds and just be with each other. It is not the way round we expect. Jeff is cheering on Carolina like he's never cheered any team on before and if you ask him he'll say it's just because they're his old teammates but truly it's because he just wants the panthers to lose...

Before puck drop on the conference finals… group chat wellness check? Especially the Oilers and Maple Leafs. I don’t think there are any Bruins in the gc but watching them hug Bergeron as they left the ice was rough

YOU COME HERE? INTO MY HOUSE BLOG and ask me about the FEELINGS OF THE BRUINS???? No fr fr tho I did see that handshake line and it was very sad. BUT a wellness check... and a couple of lil spoilers for upcoming gc

(except tumblr hates me. so uh, gonna post this in sections?)

the second piece I did for Jsoull’s upcoming MAXIFICATION 2: Commencement! 

Watch the intro here!

happy madness day (for real!)

and thank you mister jsoup for ur patronage~
