将上述C#代码转换为C++代码如下：
#include "tinyxml2.h"
#include <string>
#include <stdexcept>
std::string GetNodeValue(const std::string& nodePath, tinyxml2::XMLDocument* doc)
{
if (nodePath.empty() || doc == nullptr)
{
throw std::invalid_argument("路径" + nodePath + "下节点名为空");
}
std::string nodeValue = "";
tinyxml2::XMLNode* node = doc->SelectSingleNode(nodePath.c_str());
if (node == nullptr)
{
return "";
}
else if (node->ToElement() == nullptr)
{
throw std::invalid_argument("路径" + nodePath + "下节点类型错误");
}
nodeValue = node->ToElement()->GetText();
return nodeValue;
}
请注意，该代码同样使用了tinyxml2库，并对输入进行了一些基本的错误处理和检查。确保已经包含了相应的头文件并适当处理异常。
