Qt DOM (Document Object Model) is a module in the Qt library that provides a way to manipulate XML documents. It allows developers to create, read, modify, and delete XML elements and attributes in a tree-like structure. The Qt DOM module is based on the W3C DOM standard and provides a set of classes and methods for working with XML documents. The Qt DOM module includes the QDomDocument class, which represents an XML document, and the QDomElement class, which represents an XML element. These classes provide methods for creating, reading, and modifying XML elements and attributes. The QDomNode class is also included, which represents a node in an XML document, and provides methods for navigating the document tree.
The Qt DOM module is useful for applications that need to work with XML data, such as web browsers, RSS readers, and XML editors. It provides a convenient and efficient way to parse and manipulate XML documents, and can be used in conjunction with other Qt modules, such as Qt XML and Qt Network, to build powerful XML-based applications.
