# XML Processing

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

Qt also provides specific support for some XML dialects. For instance, 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().

These classes are relevant to XML users.

QXmlStreamAttribute | Represents a single XML attribute
QXmlStreamAttributes | Represents a vector of QXmlStreamAttribute
QXmlStreamEntityDeclaration | Represents a DTD entity declaration
QXmlStreamEntityResolver | Entity resolver for a QXmlStreamReader
QXmlStreamNamespaceDeclaration | Represents a namespace declaration
QXmlStreamNotationDeclaration | Represents a DTD notation declaration
QXmlStreamReader | Fast parser for reading well-formed XML 1.0 documents via a simple streaming API
QXmlStreamWriter | XML 1.0 writer with a simple streaming API
