[Fedora-suds-list] Unmarshaller problem?!

[Jeff Ortel]

Hey Paulo,

Thanks for your interest in Suds.  I'm glad to hear you find it helpful.

The strip() was intended to mitigate the annoying text nodes produced by
"pretty" formatted XML.  However, in reality, soap servers don't format
the XML and, as you point out, having the strip() causes problems.

Great catch!  I'll remove the strip() on trunk asap and post a notice on
the mailing list.

Thanks again,

Regards,

Jeff
