[Pywps-dev] Sending GML as data input

[Jachym Cepicky]

hi,

we moved from single-input model to collection model - that practically
means, that instead of

doc = lxml.etree.parse(request.inputs['layer'].file)

you should use

doc = lxml.etree.parse(request.inputs['layer'][0].file)

Hint: use "protocol://url" input form, e.g. in your case layer=
http://localhost/wps/point.gml

hope, it helped
