libxml2 xmlChar* cast to char*

Question

How would you convert / cast an xmlChar* to char* from the libxml2 library? Thanks.

Answer 1

如果您看一下示例，例如io2.c，您会注意到它们只是巧妙地将它转换为char *：

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

Answer 2

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.
