XML is an extremely versatile markup language, capable of labeling the 
information content of diverse data sources including structured and 
semi-structured documents, relational databases, and object repositories. A 
query language that uses the structure of XML intelligently can express 
queries across all these kinds of data, whether physically stored in XML or 
viewed as XML via middleware. Because query languages have traditionally 
been designed for specific kinds of data, most existing proposals for XML 
query languages are robust for particular types of data sources but weak 
for other types.XQuery is designed to be broadly applicable across all 
types of XML data sources.


Some XML queries are performed on data that is physically represented as 
XML, which may be either persistent or transient data. Others are performed 
on XML views of foreign data sources.


The XML Query Use Cases document gives a set of use cases where XML queries 
might be used:

XQuery is designed to be used in a number of different execution 
environments. Some of these
