XML Processing

Qt provides two sets of APIs to read and write well-formed XML: stream based and DOM based.

Qt also provides specific support for some XML dialects. The Qt SVG module provides the QSvgRenderer and QSvgGenerator classes to 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().
