[Axl] Printing contents of a node?

[Francis Brosnan Blazquez]

Hi Steven,

I see the issue. The function axl_node_get_content returns free text
enclosed by the node. In the function documentation there is a reference
to axl_node_is_empty. Check it. This also has to do with CHILDREN and
MIXED API. See [1] for more information.

For your case, if you are trying to print out the content of a
particular node, no matter if it has free text or mixed with more nodes
you can use: axl_node_dump. Taking your example it should look like:

   node = axl_doc_get_root (doc);
   axl_node_dump (node, &value, NULL);
   printf ("%s \n", value);
   axl_free (value);

Cheers!
