What you appear to be asking for is going to take a lot of work.
Firstly you could validate against a schema using standard methods. Then you 
want some non XML Infoset validation. This is the tricky part as the 
following three lines all have the same infoset but are different when 
viewed as strings:

<data id="ID1"><child name="joe" age="44"/></data>

<data id='ID1'><child age="44" name="joe"/></data>

<data id="ID1"><child name="joe" age="44"></child></data>

I don't know of any utility that can do this.
