FW: [jdom-interest] & in namespace

[Klotz, Leigh]

Not to say that this shouldn't be fixed, but just as an aside, many people now use ';' rather than '&' as the separator character in order to avoid causing all these problems.

Here's a note from the W3C on the use of semicolon with PHP:
http://www.w3.org/QA/2005/04/php-session

Note that the XForms 1.0 Recommendation (I was an editor) also by default uses ';' as the separator but allows you to specify '&'.

Hello Tatu,

Yes, I agree with Elliotte's suspect that namespace URI must actually contain "&" and not "&". The author of the WSDL document that I have might have intended the same. However such URI's (URI with query in it) cannot be entered "as is" in an XML document, they need to be escaped (I think this what Elliotte meant when he said "escaped in XML context").

This is exactly the problem that I am facing. I get a WSDL file by user (which is an XML file and hence has "&" and not "&" in namespace URI). I also agree to your comment that namespace URI's should not have ampersands.

Did you get my point? What did you mean when you said: " Please re-read Elliotte's response: it was 100% accurate.". Did I miss out something?

I tried same with Xerces's XMLSerializer and it works fine.

What do you feel? Is this a bug in JDOM? How should we proceed?

With Regards,
Aniruddha Deshpande

Please re-read Elliotte's response: it was 100%
accurate. It is possible that JDom's serializer
(outputter) does not quote values of namespace URIs,
and if so, it could and should be fixed.

I would also comment that using namespace URIs with
ampersands is a bad idea.
