To parse an XML file using TinyXML, you can follow these steps:

  1. Download the library files and headers of TinyXML, and include them in your project.
  2. Create a TiXmlDocument object to represent an XML document.
TiXmlDocument doc;
  1. Upload document
if (doc.LoadFile("example.xml")) {
    // XML文件加载成功
} else {
    // XML文件加载失败
}
  1. Main element
TiXmlElement* root = doc.RootElement();
  1. InitialElement
  2. The element that comes directly after.
// 遍历根元素的子元素
for (TiXmlElement* elem = root->FirstChildElement(); elem != nullptr; elem = elem->NextSiblingElement()) {
    // 处理每个子元素
}
  1. Characteristic
const char* value = elem->Attribute("attribute_name");
  1. Obtain the text
const char* text = elem->GetText();
  1. Assign a value
elem->SetValue("new_value");
  1. Preserve the document.
doc.SaveFile("example.xml");

The above are the basic steps for parsing an XML file using TinyXML. Depending on your specific needs, you can utilize more TinyXML methods and attributes to handle the parsing and manipulation of XML documents.
