Jsoup: Parsing html out of a piece of javascript

Does anyone of you know how to get html out of a javascript onmouseover event with Jsoup? That might sound vague, so here is is the code:

<table onmouseover="showHoverInfo('', '<a href="somelink"><b>sometext</b>/a><br /> Some other text <br /> <a href="some other link"><b>Some text</b></a>')"

And it goes on. What I would like to know, is: how do I get the html code out of the showHoverInfo() method, using Jsoup?

All help is appreciated.

You can find the onmouseover attribute via .attr() and then process the obtained string (in the example below I use regex) to get the parameter value you want:

import java.util.regex.*;
import org.jsoup.Jsoup;
import org.jsoup.nodes.*;

public class JSoupGetAttributeExample {
    public static void main(String[] args) {
        Document doc = Jsoup.parse("<html><body><div>example</div>" +
        "<table id='myTable' onmouseover=\"showHoverInfo('', '<a href=\\\'somelink\\\'><b>sometext</b>/a><br /> Some other text <br /> <a href=\\\'some other link\\\'><b>Some text</b></a>')\" >" +
        "   <tr>" +
        "       <td>"+
        "       </td>"+
        "   </tr>" +
        "</table>" +
        "</body></html>");
        Element myTable = doc.getElementById("myTable");
        String onmouseover = myTable.attr("onmouseover");
        System.out.println("onmouseover ATTRIBUTE: "+onmouseover);

        /* String processing to get the HTML (second) parameter */
        String secondParameter = null;
        Pattern p = Pattern.compile("showHoverInfo\\('.*', '(.*?)'\\)");
        Matcher m = p.matcher(onmouseover);
        if (m.find()) {
            secondParameter = m.group(1);
        }
        System.out.println("\nHTML PARAMETER: "+secondParameter);
    }
}

Output:

onmouseover ATTRIBUTE: showHoverInfo('', '<a href=\'somelink\'><b>sometext</b>/a><br /> Some other text <br /> <a href=\'some other link\'><b>Some text</b></a>')

HTML PARAMETER: <a href=\'somelink\'><b>sometext</b>/a><br /> Some other text <br /> <a href=\'some other link\'><b>Some text</b></a>
