TiXmlDocument is a package library in C++ that provides functions for parsing, manipulating, and creating XML documents. One function in TiXmlDocument is FirstChildElement, which returns a pointer to the first child element of a node.
In this example, a TiXmlDocument object is created from an XML file called "example.xml". The RootElement function returns a pointer to the root element of the document, and the FirstChildElement function is used to obtain a pointer to the first child element of the root node.
Example 2:
TiXmlDocument newDoc; TiXmlElement* root = new TiXmlElement("root"); newDoc.LinkEndChild(root); TiXmlElement* child = new TiXmlElement("child"); root->LinkEndChild(child); TiXmlElement* firstChild = root->FirstChildElement();
In this example, a new TiXmlDocument object is created without an XML file. A root element is created using the TiXmlElement constructor, and added to the document using the LinkEndChild function. A child element is created and added to the root element. Finally, the FirstChildElement function is used to obtain a pointer to the first child element of the root node.
