Comparing two files

Question

Hi,

I have two files.

In 1st file:

<?xml version="1.0" encoding="UTF-16"?>

<king version="4.0" ExtFileType="Extract">

<Header>

<FFD GUID="{F5C91E25-E904-4AD0-AA6A-41FD0A5A12E4}" Name=""/><SecureSeg level="no"/><HistoryOpt active="no"/>

<Header>

in 2nd file:

[FileVersion]

GUID={F5C91E25-E904-4AD0-AA6A-41FD0A5A12E4}

Version=9

MarkupVersion=0

DisplayName=XML-MDB-Satzweise-nxt

FileExtension=*.xml

How can i compare two files Based on GUID.  If these two GUID's are equal than two files are the same.

Thanks
