TiXmlNode::FirstChildElement is a method from the TinyXML library for C++. It is used to retrieve the first child element of a TiXmlNode object. TiXmlNode can be thought of as a generic node in the XML document, while TiXmlElement is a specific type of node that represents an element in the document.
Here are some code examples:
Example 1: TiXmlDocument doc("example.xml"); doc.LoadFile(); TiXmlElement* root = doc.RootElement(); TiXmlElement* child = root->FirstChildElement(); if(child) { // do something with child element }
This code loads an XML document from a file called "example.xml", gets the root element of the document, and retrieves the first child element of the root. If there is a child element, it can be accessed and manipulated further.
Example 2: TiXmlHandle docHandle(&doc); TiXmlElement* child = docHandle.FirstChildElement("root").FirstChildElement("child").Element(); if(child) { // do something with child element }
This code uses a TiXmlHandle, which is essentially a wrapper around a TiXmlNode that allows for easier navigation through the document hierarchy. It retrieves the first child element named "child" that is a child of a root element named "root". If the element exists, it can be accessed and manipulated further.
In both examples, the TiXmlNode::FirstChildElement method is used to retrieve a specific child element of a parent element. The TinyXML library is used in both cases.
