XQuery Tutorials

The QtXmlPatterns module [qt.io] allows developers to use XQuery [w3.org] in Qt applications to select, extract and aggregate data in XML or similarly-structured files. The Qt Quarterly newsletters have provided a series of good tutorials on using XQuery.

• Serious Enquiries with XQuery [doc.qt.digia.com] by Kavindra Devi Palaraja includes code and commentary to implement a simple Qt-based Web robot which can be used to perform some basic XQuery queries such as listing elements and checking links in HTML documents.

• Checking the Weather with XQuery [qt.io] by David Boddie shows how to construct queries that retain and transform the structure of the XML document, not just the data.

• Querying Generic Data with XQuery [qt.io] is a follow-up article from David where he looks at the ability of the query engine to be used with non-XML sources of data and the possibility of applying this feature to models of XML documents in order to visualize the output of queries.
