Simply be careful to differentiate popular and 
applicable by necessity.

Depending on the data source, it is likely that 
SQL will be the most industrially used XML query 
language for some time.  It has the advantage 
of clarity, ease, and years of experience in 
optimization.   The XPath syntax is gnomic and  
prone to misinterpretation particularly when 
using namespaces.  The bulk of data sources 
are relational.  Before using XQuery, look at 
the tools, for example, SQLServer and inquire 
into the SQL extensions that return XML to 
see if they are adequate.  In very many cases, 
they will be and will prove to be less difficult 
to learn and apply.   

The thorniest discussion these days is explaining 
to customers, managers and developers when XML 
and indeed most WWW technology is not 
appropriate for the task at hand.

The most widely used/implemented XML query language is probably XPath:

In the future, XQuery from the W3C will probably be equally popular:
