Parser joburlparser=new Parser("
http://careers2.hiredesk.net/viewjobs/jobdetail.asp?Comp=oci&PROJ_ID={5e86df59-eb37-4e01-864a-e7662b31e44b}&sCOMP_ID={D3C729A8-A506-438B-8840-C1615DD4E822}&sPers_ID=&tp_id=1
");
NodeList jobidList=joburlparser.parse(new
HasAttributeFilter("class","FormContentFieldValue"));
jobidList.extractAllNodesThatMatch(new
TagNameFilter("TD"));
System.out.println(jobidlist.toHtml());
NodeList
jobid_child=jobidlist.elementAt(3).getChildren();
System.out.println(jobid_child.toHtml());
this gives me the jobId ,but i do not want to use elementAt(3).
