[libxml++] problem returning a node

[Josh Tharp <joshtharp gmail com>]

I have a domparser setup and it parses my xml file fine without any
error. I can transverse through the doc tree fine with
parser.get_document()->get_root_node() and iterating using the
recursion example provided in the docs.

What i am having trouble with is breaking up different parsing tasks into functions.
In my function:

const xmlpp::Node* RssData::getElementTag(const xmlpp::Node* node, const Glib::ustring tagname)
{
    std::cout<<"Node loop: get_name()node: "<<node->get_name()<<std::endl;
    
    xmlpp::Node::NodeList nlist = node->get_children();
    if(!nlist.empty())
    {
        for(xmlpp::Node::NodeList::const_iterator itr = nlist.begin(); itr != nlist.end(); ++itr)
        {
            if((*itr)->get_name() == tagname)
            {
           
    std::cout<<"Title tag found try to
return"<<std::endl;
                return (*itr);
            }
            else
                getElementTag((*itr), tagname);
        }
    }
}

The function is able to find a matching node and will return without
errors but it does not return a valid address to a node in the
doctree.  I get a seg fault after trying to use the node pased
from getElementTag (eg node->get_name() will segfault because it
does not point to a valid address).

the function is passed a const node pointer returned from
parser.get_document()->get_root_node() and a string tagname to match
against a node.  It will transverse the tree till it finds a
matching node and try to return a pointer to that node so it can be use
elsewhere.
I'm not sure if nodelist is a copy of node's children and thus when the
function ends they are no longer accessible, but i understand them to
be a list<node*> right?
I am sorry if this is a simple logic error, just trying to get past this.
