TinyXML is a C++ library used for parsing and generating XML documents. It is lightweight and can easily be embedded into other C++ projects. TinyXML offers a simple and intuitive API, making it easy to work with XML documents.

The following operations can be completed using TinyXML:

  1. Parse XML documents: Using the TinyXML API, XML documents can be parsed into a tree-like structure, facilitating subsequent processing and manipulation.
  2. Traverse XML document: You can utilize the TinyXML API to iterate through the various nodes of the XML document, retrieving information such as the node’s name, attributes, and content.
  3. Search XML nodes: Specific XML nodes can be located by their name and path, making it convenient to access the required data.
  4. Modify XML nodes: Use the TinyXML API to update node properties and contents, enabling modifications to XML documents.
  5. Generate XML documents: You can easily create XML documents in a tree structure using the API of TinyXML, which makes it convenient to save data in XML format.

Using TinyXML is very simple, just include the corresponding header file and link library file. In your code, you can parse, modify, and generate XML documents by creating a TiXmlDocument object and calling methods of that object. For example:

#include "tinyxml.h"

int main() {
    // 解析XML文档
    TiXmlDocument doc("example.xml");
    if (doc.LoadFile()) {
        // 找到根节点
        TiXmlElement* root = doc.RootElement();
        if (root) {
            // 遍历子节点
            for (TiXmlElement* element = root->FirstChildElement(); element; element = element->NextSiblingElement()) {
                // 输出节点名称
                printf("Element name: %s\n", element->Value());
                
                // 输出节点属性
                TiXmlAttribute* attribute = element->FirstAttribute();
                while (attribute) {
                    printf("Attribute name: %s, Attribute value: %s\n", attribute->Name(), attribute->Value());
                    attribute = attribute->Next();
                }
                
                // 输出节点内容
                printf("Element content: %s\n", element->GetText());
            }
        }
    }
    
    return 0;
}

The above code demonstrates how to parse an XML document and iterate through its node names, attributes, and content. Of course, TinyXML also offers many other APIs for performing additional operations, which can be found in the official documentation.
