[xmlpp-common] how to get the contents of a xmlpp::Node ?

[Jan P. <jan...@ya...>]

hi :)

I know this is a dumb question ... but apparently there is no obvious answers, and I don't want to write something to go through all the "text" children ...

I tried the following:

    xmlpp::Node *frob_node = get_nontext_node( root->get_children() ); // i wrote this utility function to search for the first non "text" child, is there an easier way ?
    if ( ! frob_node || frob_node->get_name() != "frob" )
        throw runtime_error( "FlickrAPI::getFrob(): missing \"frob\" child for root \"rsp\" node, got "+frob_node->get_name() );
    
    xmlpp::ContentNode content( frob_node->cobj() );
    string result = content.get_content();

but as expected, I got memory errors because of and object being freed twice (frob_node->cobj() I believe):

*** glibc detected *** double free or corruption (out): 0x00007fffffb14cf0 ***
Aborted


thanks for any hints
