我试图从 XML 文件导入数据并将它们保存在 5D 地图中
// declaration of the map
map<char *, map<char *, map<char*, map<char *, map<char*, map<char*, char*, cmp_str>, cmp_str>, cmp_str>, cmp_str>, cmp_str>, cmp_str> XmlData;
我使用 RapidXML 解析器进行 XML 解析
file<> xmlFile("jobs.xml");
xml_document<> doc;
doc.parse<0>(xmlFile.data());
xml_node<> *node = doc.first_node();
while(node != 0) {
xml_node<> *child = node->first_node();
while (child != 0)
{
xml_node<> *subchild = child->first_node();
while (subchild != 0)
{
xml_node<> *subsubchild = subchild->first_node();
while (subsubchild != 0)
{
xml_node<> *subsubsubchild = subchild->first_node();
while (subsubsubchild != 0)
{
// the error appears here
XmlData[node->name()][child->name()][subchild->name()][subsubchild->name()][subsubsubchild->name()] = subsubsubchild->value();
subsubsubchild = subsubsubchild->next_sibling();
}
subsubchild = subsubchild->next_sibling();
}
subchild = subchild->next_sibling();
}
child = child->next_sibling();
}
node = node->next_sibling();
}
我不得不使用 5 个 while 循环来迭代所有节点

在 CentOS 6 下使用 g++ 和 c++0x 进行编译时,出现以下错误:
