tinyxml2库下 怎么将传入的const char* 存在xmldocument对象中,然后在对xmldocumen对象进行序列化,然后在输出xml文档

使用tinyxml2库将const char*存储在XMLDocument对象中的步骤如下:
1. 创建一个XMLDocument对象:`XMLDocument doc;`
2. 使用`doc.Parse()`函数将const char*解析为XMLDocument对象:`doc.Parse(const char*);`
3. 在XMLDocument对象中创建XML元素和属性,设置其值和属性值,以构建XML文档。
将XMLDocument对象序列化并输出为XML文档的步骤如下:
1. 创建一个XMLPrinter对象:`XMLPrinter printer;`
2. 使用`doc.Accept()`函数将XMLDocument对象传递给XMLPrinter对象:`doc.Accept(&printer);`
3. 在XMLPrinter对象上调用`CStr()`函数,输出XML文档:`printf("%s", printer.CStr());`
以下是完整的代码示例:
```c++
#include "tinyxml2.h"
#include <cstdio>
using namespace tinyxml2;
int main()
{
const char* xml = "<root><element attribute=\"value\">text</element></root>";
// Parse the const char* and store it in an XMLDocument object
XMLDocument doc;
doc.Parse(xml);
// Build the XML document
XMLElement* root = doc.RootElement();
XMLElement* element = root->FirstChildElement("element");
element->SetText("new text");
element->SetAttribute("new_attribute", "new_value");
// Serialize and output the XML document
XMLPrinter printer;
doc.Accept(&printer);
printf("%s", printer.CStr());
return 0;
}
