Hi Martin,
Regard your questions:
part of my xml file looks like:
<?xml version="1.0" ?>
<?xml-stylesheet type="text/xsl" href="Diagnostics.xsl"?>
<Diag_Tests_Results>
       <Test>
               <TITLE>PASS-FAIL TESTS:test pass</TITLE>
               <Test_Result>Pass</Test_Result>
               <Test_Line1Description>The recived file has been 
corrupt</Test_Line1Description>
               <Test_Line2Description>Please check the 
memory</Test_Line2Description>               
               <Test_Line3Description>Replace the memory 
module</Test_Line3Description>               
               <Test_Expected_Results>56 </Test_Expected_Results>  
               <Test_Received_Results>76</Test_Received_Results>
		   	   <XOR>6+5</expression></XOR>
		       <Error_Code>298</Error_Code>
       </Test>

and i want to combine the 6+5 and show it in my browser.
