& XSLT Hi, 
 
I have been reading about various XML parsing modules in Perl (XML::Simple, XML::XPath, XML:
:Twig, XML::LibXML, XML::SAX, etc).  I was hoping to get some advice on which module can bes
t help me with a particular problem.  I need to:
 
--Parse an existing XML document and extract the relevant elements (I am using XML::SAX for 
this)
--Write the relevant data to a new XML file - need a module for this
--Add elements to the new file over time - need a module for this
 
My XML file will be extremely simple - only two elements deep.  I would like to be able to s
imply append an element with attributes to the root element rather than querying for and app
ending to a particular node.  Here is a sample XML document:
 
<?xml version="1.0" encoding="UTF-8"?>   
<testcaselist> 
         <testcase searchPath="chassis/fileStorageLocation/locationType" searchValue="flash"
/>   
         <testcase searchPath="chassis/fileStorageLocation/size" searchValue="7679"/>   
         <testcase searchPath="chassis/fileStorageLocation/available" searchValue="2497"/>   
         <testcase searchPath="chassis/fileStorageLocation/imageFile/filename" searchValue="
c3620-i-mz.120-28d.bin"/>   
         <testcase searchPath="chassis/fileStorageLocation/imageFile/filesize" searchValue="
11817"/> 
</testcaselist>   
 
Any suggestions would be greatly appreciated.
 
Regards,
Amanda
