"XML Namespaces must die"

Fri 04 March 2005

I hate XML namespaces. I strongly dislike them.

I will rant about this in detail in the future, as if there hasn't been enough vitriol on this topic already. But let me present my current problem:

gsoap is returning this:

<soap-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:cmoda="urn:ows:cmoda:0.1">  
</soap><soap-ENV:Body>  
<cmoda:updateOfferBidsResponse>  
<setofresults>  
<item>  
<source-id>1</source>  
<sequence-num>1</sequence>  
<offer-id>123</offer>  
<success>true</success>  
<reason>CMODA-UPDATE-OFFER-BID-UNDEF</reason>  
</item>  
</setofresults>  
</cmoda>  
</soap>  

Axis is the client, and doesn't like it. Complains of source-id not being correct. Turns out, it has a problem with the namespace. Most SOAP servers would return the result as:

 <updateOfferBidsResponse xmlns="urn:ows:cmoda:0.1">  

Note the inclusion of the namespace within this tag.

I looked thru the XML namespace tutorials, and I can tell this version means the child nodes of updateOfferBidsResponse are in the namespace specified here. But what does the gsoap version mean? Does

<cmoda:updateOfferBidsResponse>

also mean all children of updateOfferBidsResponse are in the cmoda namespace, or are they in some other namespace? I'm no genius, but I've looked around a bit and I can't find the answer. In any case, either the Axis or the gSOAP folks didn't quite get it either, or better yet, the XML libraries they're looking at got it wrong or disagree.

I'm saying, people smarter than I don't get it.

I'm trackback'ing Mr. Tim Bray's long ago post in case by some magic he becomes aware of this and sheds some light my way (he's the co-author of the spec, and I've met him once or twice, so why not bother him)
