Not yet. Unfortunately, none of the major browsers support XQuery just yet, although rumors abound that XQuery support is underway for upcoming releases.
Q.
How does XQuery differ from XPath?
A.
XPath is a language used for addressing within XML documents. XQuery is a query language used to filter data within XML documents. XPath can also be used for pattern matching on XML documents and in fact serves that role within XQuery. Fundamentally, the two languages differ more in purpose than in design. XQuery solves a larger problem and incorporates XPath toward that end. Chapter 22 covers XPath in detail.
