The prefix don't allow use the "_" character

[aperi2007]

When using a prefix name like this:

<layer ns_prefix='ambiti_amministrativi'
ns_uri="http://www.regione.toscana.it/"

Tinyows give an error because the "ambiti_amministrativi" name is not compatible with the parser:
((\w:)?\w(=\w)?){1,}

If I remove the "_" using for example
<layer ns_prefix='ambitiamministrativi'
ns_uri="http://www.regione.toscana.it/"

It start to work.

Yes.

I test it and verify the with this patch tinyows allow to have a ns_prefix with the character "_" in it.

Without this patch the tinyows give the usual error.

Just a details. I guess this error will born only when the request is using the POST method.
However the patch will resolve it.

Thx,

I ran into this issue as well when one of the examples in the "PostGIS Cookbook" book from Packt.
