Maybe we can discuss if it makes sense to do those typedefs (ast_xml_text
and ast_xml_attr). But the casting is being done on ->AST_XML_NAME (actually
on node->name this is because of a signedness warning) and not when working
with the typedefs ast_xml_attr and ast_xml_text.
->name is defined as xmlChar * (libxml2 implementation, maybe 'unsigned char
*' ??? didn't check it...).

To avoid this inline casting we can create a MACRO definition like NAME(a)
((const char *)a->name) and move all to this type of coding like:
NEXT(a) (a->next)
PREV(a) (a->prev)
CHILD(a) (a->children)
(I have started coding with this approach but I think is harder to
understand (??))

Hope this help you understand the problem to find (if it exists) a better
