how to directly get the data held by js

[Viking Yu]

Hi All,

I'm using cobra to get some specific data from a website.  According to the codes from http://www.benjysbrain.com/misc/cobra/,
I can get the data by  document.getElementById(elementId)  after iterating the whole webpage. It is a heavy workload comparing with a few data I need. So, I use another approach, i.e. only parse my interested part (nodes) . i.e.

HTMLDocument document = (HTMLDocumentImpl) dbi.createDocument(inputSource);
((HTMLDocumentImpl)document).addDocumentNotificationListener(this);
HtmlParser parser = new HtmlParser(uaContext, document);

HTMLDivElement infoNode = new HTMLDivElementImpl("myTab1_Content0");
doTree((Node) infoNode);
parser.parse(lineNumberReader, infoNode);

But I can 't  get the data by  document.getElementById("myTab1_Content0"); The ralated part of html is following:

  ＜ｄｉｖ　ｉｄ="myTab1_Content0" ＞
  ＜ｄｉｖ ｃｌａｓｓ="business_card"  ＞                                   
＜ｄｌ>
＜ｓｃｒｉｐｔ＞
if (saler.dyPropKey){
   for (var i=0;i<saler.dyPropKey.length;i++){    
    document.write('<dd><span>'+ saler.dyPropKey_ +'：</span><p>'+ saler.dyPropValue +'</p></dd>');
}
    }
＜／ｓｃｒｉｐｔ＞
＜／ｄｌ>
   ＜/ｄｉｖ＞　

  I have tried to parse some parent nodes/element of the interested element, but also failed.   Does anyone have the a solution? Any suggetion or help will be very appreciated.

Is this something XPath could handle?  I've only used XPath to extract nodes by type, but there might be a way to look by attribute.
