[Tclxml-users] Possible bug with xml default namespace serialization?

[Steve M. <st...@re...>]

I am seeing behavior which I do not expect but I'm not positive its a 
bug.  If I serialize an XML document with a default namespace (e.g. 
xmlns="some-uri"), I get an null namespace in the output elements (e.g. 
<:tag> instead of <tag>).

For example, I parse the following XML using dom::parse

<rootnode xmlns="http://myuri">
   <tag>value</tag>
</rootnode>

Then I serialize the dom with dom::serialize, I get the following:

<?xml version='1.0'?>
<!DOCTYPE :rootnode>
<:rootnode xmlns:="http://myuri">
   <:tag1>value</:tag1>
</:rootnode>

Note the semicolon before the element names.  I did not expect this 
semicolon to be included.

Am I defining my XML document incorrectly?  It was my understanding that 
the default namespace (xmlns w/o any suffix) was the namespace for any 
element that did not have an explicit namespace attached.  I would 
expect the output from the serialize function to be identical to the 
input in this case.

I made a tweak to the dom library as follows which results in the 
behavior I desired:
Change line 2851 in dom.tcl (tcldom 3.0b1) from:
        } elseif {[string length $node(node:namespaceURI)]} {
to:
        } elseif {[string length $node(node:namespaceURI)] && \
           [string length [GetNamespacePrefix $token 
$node(node:namespaceURI)]]} {

* This does not fix the printing of the xmlns attribute in the root 
element and the DOCTYPE.

but I'm not sure if this is the right thing to do.  Essentially my goal 
was that if the xmlns prefix is null, then don't prepend.  There might 
be a more appropriate place to handle this thought (if indeed I am using 
XML correctly).

If needed, let me know and I'll log a bug.

Thx, Steve

Looks like a bug to me.  I'll make sure the test suite has a test case
for this situation.

Given your previous post, I assume you're using 3.0b1?
The pure-Tcl implementation?

Cheers,

Re: [Tclxml-users] Possible bug with xml default namespace serialization?

[Steve M. <st...@re...>]

Thanks!

Yes, this problem happens in both the 2.6 and 3.0b1 versions of the 
pure-Tcl parser.  It does not happen with the 3.0b1 Combined Binary 
Packages available on the tclxml project page.

Thx, Steve
