Hello good programmers,
I have a situation, where I need to make an excel document that contains specific information from 7 XML documents.

Any time I open this excel document, I want the information there to be updated (read from those 7 XML files), if information in any of xml documents have been changed.

What is the best way to do that?

I have no idea...

Can someone help me?

I do not know any programming language, but I can write queries in Xpath.
