QDom

QDom is a Qt class that provides an interface for reading and writing XML documents. It is part of the Qt framework, a cross-platform application development framework. QDom allows developers to parse XML data into a tree structure, which can then be navigated and manipulated.

The QDomDocument class represents the entire XML document. It can be loaded from a file or a string. Individual XML elements are represented by QDomNode objects. These nodes can be elements, attributes, text, or comments. QDomNode provides methods to access the node's name, type, and children.

QDomElement is a specialized type of QDomNode that represents an XML element. It allows access to the element's attributes and child elements. QDomAttr represents an XML attribute, providing methods to get and set its name and value. QDomText represents the text content within an XML element.

To write XML data, developers can create a QDomDocument and then add elements, attributes, and text nodes to it. The document can then be serialized to a string or written to a file. QDom is designed to be easy to use and integrates seamlessly with other Qt classes. It is a fundamental tool for any application that needs to interact with XML data within the Qt environment.
