[libxml++] [PATCH] clear_internal_subset()

[Thomas J. <tho...@in...>]

Hi,

I wanted to replace a dtd reference in a parsed document with a new one. Just 
calling set_internal_subset doesn't work, libxml checks if we already have at 
dtd and breaks.

So I wrote the clear_internal_subset function.

But since I haven't done much libxml hacking yet, I'm not sure if I got all 
the node linking, referencing and memory allocating right. I would highly 
appreciate it if a libxml guru could take a look at it.
Feel free to include this patch to libxml++.

Kind regards,
Thomas
