Search Strings and Compare

Hello AutoIT MPVs,

Can somebody help me how to search a value of an element in xml file and compare with a value of an element in other xml file within the directory and creates a log file if error or match.

e.g.

The element to look for is <url> and the value is http://some-url.com - 1st xml
The element to look for is <website> and the value is http://some-url.com - 2nd xml

Please I need it badly. Thanks.
