I recently stumbled across this:
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://schemas.xmlsoap.org/ws/2004/08/addressing">
<s:Header>
<a:Action s:mustUnderstand="1">http://schemas.xmlsoap.org/ws/2005/04/discovery/Probe</a:Action>
<a:MessageID>uuid:21859bf9-6193-4c8a-ad50-d082e6d296ab</a:MessageID>
<a:ReplyTo>
<a:Address>http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous</a:Address>
</a:ReplyTo>
<a:To s:mustUnderstand="1">urn:schemas-xmlsoap-org:ws:2005:04:discovery</a:To>
</s:Header>
<s:Body>
<Probe xmlns="http://schemas.xmlsoap.org/ws/2005/04/discovery">
<d:Types xmlns:d="http://schemas.xmlsoap.org/ws/2005/04/discovery" xmlns:dp0="http://www.onvif.org/ver10/network/wsdl">dp0:NetworkVideoTransmitter</d:Types>
</Probe>
</s:Body>
</s:Envelope>
One thing that perplexes me is the line:-
<d:Types xmlns:d="http://schemas.xmlsoap.org/ws/2005/04/discovery" xmlns:dp0="http://www.onvif.org/ver10/network/wsdl">dp0:NetworkVideoTransmitter</d:Types>
The namespace dp0
is actually used in the element value, does that mean anything at all?
