I'm trying to implement a simple xml-reader in c++ using libxml++. So far i've manged to open the xml-document, print the relevant parts and then exit. the problem is that i get a segmentation fault when exiting.
Code:
int main()
{
Glib::ustring file_name = "test.xml";
xmlpp::DomParser test(file_name);
xmlpp::Document* test_xml = test.get_document();
xmlpp::Element* root_node = test_xml->get_root_node();
xmlpp::Element::NodeList children = root_node->get_children(Glib::ustring("item"));
xmlpp::Element::NodeList::iterator i;
i = children.begin();
while (i != children.end())
{
xmlpp::Element::NodeList item_list = (*i)->get_children(Glib::ustring("title"));
xmlpp::Element::NodeList::iterator g;
g = item_list.begin();
while (g!=item_list.end())
{
if (xmlpp::Element((*g)->cobj()).has_child_text())
{
xmlpp::Element test((*g)->cobj());
cout << (test.get_child_text())->get_content() << endl;
}
g++;
}
i++;
}
}
Is there something missing? Do i have to close the specific document in some way? gdb outputs:

so obviously there is something wrong with how the destructor works?
