XML Processing

In addition to core XML support, classes for higher level querying and manipulation of XML data are provided by the Qt XML Patterns module. In the Qt SVG module, the QSvgRenderer and QSvgGenerator classes can read and write a subset of SVG, an XML-based file format. Qt also provides helper functions that may be useful to those working with XML and XHTML: see Qt::escape() and Qt::convertFromPlainText().
