Allthough the .net server doesn't have any problem with it, there is a mismatch in the namespace
my php request:
xmlns:ns1="http://www.itworks.nl/"
the definition with the .net server:
xmlns:itw="http://www.itworks.nl/"
I would like to know if it is possible to give the alias "itw" to the namespace so it is replacing the default ns1 notation. Is it possible?
It's unnecessary. It's just locally used prefix, which you define and use later - basic XML knowledge. When the XML is parsed, all these prefix names are (should be) discarded anyway.
<something xmlns:prefix="
http://server.com">
<prefix:inner>text</prefix:inner>
</something>
