XML Processing

An Overview of the XML processing facilities in Qt.

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 convertFromPlainText() .

Classes for XML Processing

These classes are relevant to XML users.

PySide6.QtXml.QDomImplementation	The QDomImplementation class provides information about the features of the DOM implementation.
PySide6.QtXml.QDomNodeList	The QDomNodeList class is a list of QDomNode objects.
PySide6.QtXml.QDomNode	The QDomNode class is the base class for all the nodes in a DOM tree.
PySide6.QtXml.QDomNamedNodeMap	The QDomNamedNodeMap class contains a collection of nodes that can be accessed by name.
PySide6.QtXml.QDomDocumentType	The QDomDocumentType class is the representation of the DTD in the document tree.
PySide6.QtXml.QDomDocumentFragment	The QDomDocumentFragment class is a tree of QDomNodes which is not usually a complete QDomDocument.
PySide6.QtXml.QDomCharacterData	The QDomCharacterData class represents a generic string in the DOM.
PySide6.QtXml.QDomAttr	The QDomAttr class represents one attribute of a QDomElement.
PySide6.QtXml.QDomElement	The QDomElement class represents one element in the DOM tree.
PySide6.QtXml.QDomText	The QDomText class represents text data in the parsed XML document.
PySide6.QtXml.QDomComment	The QDomComment class represents an XML comment.
PySide6.QtXml.QDomCDATASection	The QDomCDATASection class represents an XML CDATA section.
PySide6.QtXml.QDomNotation	The QDomNotation class represents an XML notation.
PySide6.QtXml.QDomEntity	The QDomEntity class represents an XML entity.
PySide6.QtXml.QDomEntityReference	The QDomEntityReference class represents an XML entity reference.
PySide6.QtXml.QDomProcessingInstruction	The QDomProcessingInstruction class represents an XML processing instruction.
PySide6.QtXml.QDomDocument	The QDomDocument class represents an XML document.
PySide6.QtCore.QXmlStreamEntityResolver	The QXmlStreamEntityResolver class provides an entity resolver for a QXmlStreamReader.
PySide6.QtCore.QXmlStreamReader	The QXmlStreamReader class provides a fast parser for reading well-formed XML via a simple streaming API.
PySide6.QtCore.QXmlStreamAttribute	The QXmlStreamAttribute class represents a single XML attribute.
PySide6.QtCore.QXmlStreamAttributes	The QXmlStreamAttributes class represents a vector of QXmlStreamAttribute.
PySide6.QtCore.QXmlStreamNotationDeclaration	The QXmlStreamNotationDeclaration class represents a DTD notation declaration.
PySide6.QtCore.QXmlStreamNamespaceDeclaration	The QXmlStreamNamespaceDeclaration class represents a namespace declaration.
PySide6.QtCore.QXmlStreamEntityDeclaration	The QXmlStreamEntityDeclaration class represents a DTD entity declaration.
PySide6.QtCore.QXmlStreamWriter	The QXmlStreamWriter class provides an XML writer with a simple streaming API.
