Getting data from a form using java

<div></div>
    <div></div>
           <div></div>
            <div></div>
                <ul>
        <form id=the_main_form method="post">
                   <li>
                       <div></div>
                       <div> <h2> 
                <a onclick="xyz;" target="_blank" href="http://sample.com" style="text-decoration:underline;">This is sample</a>
                 </h2></div>
                       <div></div>
                        <div></div>
                      </li>

there are 50 li's like that

I have posted the snip of the html from a big HTML.

<div> </div> => means there is data in between them removed the data as it is not neccessary.

I would like to know how the JSOUP- select statement be to extract the href and Text?

I selected doc.select("div div div ul xxxx");

where xxx is form ..shoud I give the form id (or) how should I do that

Try this:

Elements allLis = doc.select("#the_main_form > li ");
for (Element li : allLis) {
    Element a = li.select("div:eq(1) > h2 > a");
    String href = a.attr("href");
    String text = a.text();
}

Hope it helps!

EDIT:

Elements allLis = doc.select("#the_main_form > li ");

This part of the code gets all <li> tags that are inside the <form> with id #the_main_form.

Element a = li.select("div:eq(1) > h2 > a");

Then we iterate over all the <li> tags and get <a> tags, by first getting <div> tags ( the second one inside all <li>s by using index=1 -> div:eq(1)) then getting <h2> tags, where our <a> tags are present.

Hope you understand now! :)

Please try this:

package com.stackoverflow.works;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;

/*
 * @ author: sarath_sivan
 */

public class HtmlParserService {

    public static void parseHtml(String html) {
        Document document = Jsoup.parse(html);
        Element linkElement = document.select("a").first();
        String linkHref = linkElement.attr("href"); // "http://sample.com"
        String linkText = linkElement.text(); // "This is sample"
        System.out.println(linkHref);
        System.out.println(linkText);
    }

    public static void main(String[] args) {
        String html = "<a onclick=\"xyz;\" target=\"_blank\" href=\"http://sample.com\" style=\"text-decoration:underline;\">This is sample</a>";
        parseHtml(html);
    }

}

Hope you have the Jsoup Library in your classpath.

Thank you!
