I have a problem in trying to filter the elements from a XML Document

basically I have an xml file that may contain

<list>
   <bookname> ..... </bookname>
   <type>
     <type1>....</type1>
     <type2>....</type2>
   </type>

and want to display elements that has the data in type2 for example... at the moment I have manage to display the each main elements in the xml document according to user specs but having trouble in filtering it according to different elements

should I be looking towards xpath ? and if so how is this implemented in javascript?

It's very simple to do this kind of thing with XSLT, either on the server or in the browser.
