libxml2 xmlChar* cast to char*

How would you convert / cast开发者_运维技巧 an xmlChar* to char* from the libxml2 library? Thanks.

If you take a look at the examples, for instance io2.c, you'll notice that they just blithely cast it to a char *:

printf("%s", (char *) xmlbuff);

Looks like it's just unsigned char. So it should be safe to cast as long as you're not doing arithmetic on it.

But, you probably don't need to as that page has the key string functionality implemented in terms of the type.
