[xml] Parsing from a compressed string

[Stefan Behnel <stefan_ml behnel de>]

Hi,

it seems that libxml2 can parse zlib compressed data from files. What would be
the right way to parse compressed data from a string in memory? And, yes, I
want to avoid unpacking it before I parse it.

Same question for serialisation? Is there anything like a compressing
OutputBuffer?

Thanks,
Stefan
