Re: [xml] xmlNodePtr properties missing xmlns:xxxx

That is because namespace is "special" and located in a linked list off other pointers. Here is a snippet of code I use to free them (get rid of them) which is the opposite of what you want, but should give you a starting point ... 

        xmlNodePtr node;
for (;node;node=node->next) { /* looping through all nodes */ 
            xmlNsPtr next;
            xmlNsPtr cur;
cur = node->ns; /* looping through all namespaces for this node */ 
            while (cur) {
                next = cur->next;
                if (cur->href) xmlFree((char *) cur->href);
                if (cur->prefix) xmlFree((char *) cur->prefix);
                cur->href = NULL;
                cur->prefix = NULL;
                xmlFree((char *)cur);
                cur = next;
            }
            node->ns = NULL;

            if (node->type == XML_ELEMENT_NODE ||
                node->type == XML_XINCLUDE_START ||
                                         node->type == XML_XINCLUDE_END) {
                cur = node->nsDef;
                while (cur) {
                        next = cur->next;
                        if (cur->href) xmlFree((char *) cur->href);
                        if (cur->prefix) xmlFree((char *) cur->prefix);
                        cur->href = NULL;
                        cur->prefix = NULL;
                        xmlFree((char *)cur);
                         cur = next;
                }
                node->nsDef = NULL;
            }
Note -- I ripped out stuff special to me and may have been a bit sloppy, but this should give you an idea.

I have an iXBRL document that I am parsing with LibXml2.  The problem I have
is that I register all the namespaces which are mostly held in the <html>
root node, no problem.  But, there are some namespace declarations in some
of the document nodes as attrbutes of that particular node.  When I get the
attributes of a particular node that has a namespace declaration and I read
the attributes thus:

   xmlAttrPtr pAttr = pCurNode->properties;

I then iterate through all the attributes, and they are all there apart from
the one named 'xmlns:xxxx="blahblahblah" .  Is there anyway I can locate
these namespace declarations, so that I can register them?

Any advice on this problem will be much appreciated.
