Comparison of XML Items

[i-fly]

I am completely new to XML so I have no idea how to do this :Suppose I have the following XML File 1 :\[code\]<Items><Item> <name> Item1 </name> <value> 10 </value></Item></Items>\[/code\]and file 2 :\[code\]<Items> <Item> <name> Item1 </name> <value> 20 </value> </Item> </Items>\[/code\]How do I compare value field of these 2 items in any way using XSLT ?
