Hi. If I get a <message/> and I will check what's the message. Should I check the <name> of the child or shall I check the ns of the child?

an XML element is uniquely identified by the combination of namespace and tag name

libstrophe provides two functions 'xmpp_stanza_get_child_by_ns' and 'xmpp_stanza_get_child_by_name'.

Ge0rG, I see, thanks!

Yes, any sensible API should let you combine both

yeah that api makes no sense

DebXWoody: there are implementations that only use the tag name, because *often* tag names are globally unique. And then you can get very far until horrible things start to happen in silent and hideous ways

The api also provides this kind of message: xmpp_handler_add (xmpp_conn_t *const conn, xmpp_handler handler, const char *const ns, const char *const name, const char *const type, void *const userdata). But I try to understand.

also child? there can be children of "name" ✏

does it return a list?

Also keep in mind that there's not a single child, each stanza (as well as any xml element) may have 0 or more child nodes (modulo schema etc)

lovetox, Looks like just the first element.

I think it would be a clean approach to define a handler for a certain namespace, and that handler would get passed all tags with that namespace

iterators are also nice

Now, I see! This may the reason why the implementation in profanity looks little bit complex. Calling a handler is just based on the first xml element. If the handler has to check what's the stanza about, it should check for something like 'list of stanza' get_stanza(name, ns).
