XQuery shows much promise for software architects and developers because it greatly reduces the amount of code you need to write to build services that work with XML. You might think XQuery does everything and is well understood, but misconceptions and misunderstandings still exist in the software development community about XQuery. In this article, Frank Cohen details and clarifies many of the myths and misunderstandings that surround XQuery.

If you work with XML, Web services, or Service Oriented Architecture (SOA), you will likely benefit from the emerging XML Query (XQuery) standard. XQuery is not even a formally accepted standard, yet dozens of implementations help software architects and developers every day. What began as a standard for querying XML documents now includes the next-generation standards for XML selection (XPath 2), XML serialization, full-text search, and functional XML data modeling. A project of this size is bound to have much myth and misunderstanding that needs to be debunked. Here are some of the more common myths and misunderstandings surrounding XQuery.
