 I need the length to pass it to other functions which do not work on #0-terminated, but length-terminated 
string functions.

Hmm...  What about following idea:

You may try to cache length of strings.
Const family of functions returns pointer to the "interned" string
from the internal Reader dictionary.  It relates to node and attribute

You may prefill it with strings need for- or expected by you using
xmlTextReaderConstString().  In the same time you can calculate
strlen() and fill both (pointer to the interned string and its length)
into e.g. array.

After that you can both save time by eliminating strcmp() and using
direct pointer comparison, and avoid strlen() calls using lookup
inside this prefilled array.

If lookup fails (unknown node or attribute), then you may fallback to
the "usual" strlen() or just ignore unknown element depending of logic
of your application.
