Summary

This hour introduced you to XQuery, which is a query language that makes it relatively easy to extract specific elements from an XML document. XQuery is analogous to SQL in the relational database world in that it allows you to construct queries that you execute against XML documents to retrieve matching data. In this lesson, you learned how to construct a variety of different kinds of queries using XQuery. You learned that XQuery is closely linked to another XML technology, XPath. You wrapped up the hour by working your way through a couple of interesting XQuery examples, which hopefully reinforced what you learned throughout the lesson as a whole.
