Getting XML Nodes based on attributes value

Re: [Intent Announcement] XML::Validator::RelaxNG | Re: Getting XML Nodes based on attributes value
& XSLT Hi All,

    I was wondering if there's a module that i can used to get only the 
nodes in an XML file based on the attributes value?

   Example XML is:

    <Things> 
       <Object Class="Pens" Location="Room"> 
             <p name="length"> 4<\p>
             <p name="thickness"> .5</p>
             <p name="color"> yellow</p>
       </Object> 
       <Object Class="Papers" Location="Room"> 
             <p name="length"> 9<\p>
             <p name="thickness"> 2</p>
             <p name="color"> yellow</p>
       </Object> 
       <Object Class="Pens" Location="Sala"> 
             <p name="length"> 4<\p>
             <p name="thickness"> .5</p>
             <p name="color"> Black</p>
       </Object> 
       <Object Class="Papers" Location="Sala"> 
             <p name="length"> 9<\p>
             <p name="thickness"> 3</p>
             <p name="color"> white</p>
       </Object> 
   </Things> 

    If I want to retrieve only the objects with class "Pens" then i 
would just execute something like

          $xml-> node("Object", "Class" => "Pens")
   
    and the module(s) will give me a hashref with two values. All 
objects, including its parameters, with class "pens" (1 in "Sala" and 1 
in "Room")?


    Thanks...

Br,
Joseph
