Iacovlev,

I have reviewed the code and can fairly conclusively say that currently
there is no mapscript mechanism to push an XML Post request into the
OWS request object to be processed as normal post requests are.

To implement this, we would need to actually implement the msIO_bufferRead()
function in mapio.c, and add a function to push data into this buffer
(something roughly like msIO_getStdoutBufferString() and
msIO_getStdoutBufferBytes() from mapscript/swiginc/msio.i but in the
opposite direction).

I have created a Trac ticket to note this issue, but I have no plans to
implement it in the forseeable future.

   http://trac.osgeo.org/mapserver/ticket/2681

I would be willing to implement it in 5.4 if there was a sufficiently savvy
collaborator willing to help test and debug it (including building from source
themselves).

NOTE: This issue only affects someone wanting to use POST requests to WxS
services from mapscript in a non-cgi environment (like mod_php or mod_python).

Best regards,
