Hey, Thanks for doing this! I'll do a more in depth review on Monday if noone beats me to it, just some quick notes: On Wed, Mar 07, 2012 at 06:02:06AM +0200, Zeeshan Ali (Khattak) wrote:

Not really useful to have a function whose only use is doing a cast for us, I'd kill it and have get_child_element_content return a char *. For functions which take a xmlChar *, cast it to char * and then return it, it may be better to use BAD_CAST to do the cast ( http://xmlsoft.org/html/libxml-xmlstring.html#BAD_CAST ) so that we can easily spot these functions if we need to some day.

Can be killed too.

Is g_str_check still useful? Actually, the whole macro is probably useless now since it's just g_assert(g_strcmp0((str1), (str2)) == 0);
