Solution 2

You should never use regex to check the format/sequence/validity of an XML file...
For that there is the XSD...XML Schema Tutorial[^]

Good answer, but the question is from October 2014. :)

Ops...All I saw is that it is on the top of the list...

I guess the OP might still be waiting for an answer - he posted a new question this afternoon, so he's still around.

How this question popped to the top after that much time?

Your answer is listed as Solution 2, so I guess Solution 1 got deleted recently.
