我用tinyxml2的库来进行解析xml，运行结果什么都没有。

要求输出运行结果是

位置1
位置2
位置3

下面是我的代码
====================
tinyxml2::XMLDocument doc;
doc.Parse(xml);

tinyxml2::XMLHandle docHandle(&doc);
tinyxml2::XMLElement *entry = docHandle.FirstChildElement("location")
.ToElement();

if (entry) {
      for (tinyxml2::XMLNode *node = entry->FirstChildElement(); node; node =2
node->NextSibling()) {
         tinyxml2::XMLElement *e = node->ToElement();
         const char *name = e->Attribute("location");
         if (name)
            cout << name << ": ";
      }
}
