Re: Compiler Errors

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

When I run your example, it crashes on
        txt_node = node_element->get_child_text();
because node_element == NULL.

mRNode has 5 children:
1. a TextNode containing a linefeed ("\n")
2. an f1 Element node
3. a TextNode containing a linefeed
4. an f2 Element node
5. a TextNode containing a linefeed

If you are only interested in f1 nodes, change
    Node::NodeList temp_lst = mRNode->get_children();
to
    Node::NodeList temp_lst = mRNode->get_children("f1");
or make more tests when you loop over all the children.
