[xml] Do xmlBuffers grow dynamically as needed?

[Holger Rauch <Holger Rauch heitec de>]

Hi!

I'm new to libxml2 and trying to extract a document fragment using
xmlNodeDump(). This function requires an xmlBufferPtr as one of its
arguments. Will calling xmlNodeDump() automatically grow a previously
xmlBufferCreate()ed xmlBuffer? If not, what are the alternatives?

Any help will be greatly appreciated!

Regards,
