#155 Namespace name assignment fails on xs:any type in certain circumstances

[Harold Solbrig]

Temporary namespace identifiers don't get recorded for

<core:v xmlns="http://www.w3.org/1999/xhtml">

<ul>

<li>entry1</li>

<li>entry2</li>

</ul>

</core:v>

should produce a toxml() of:

<core:v xmlns:ns1="http://www.w3.org/1999/xhtml">

<ns1:ul>

<li>entry1</li>
<li>entry2</li>

</ns1:ul>

</core:v>

instead, it produces:

<core:v xmlns:ns3="http://www.w3.org/1999/xhtml">

<ns1:ul>

<ns2:li>entry1</ns2:li>
<ns3:li>entry2</ns3:li>

</ns1:ul>

</core:v>

The attached file reproduces the problem and contains a "fix" that gets us at least part way towards the above, by producing:

<core:v xmlns:ns1="http://www.w3.org/1999/xhtml">

<ns1:ul>

<ns1:li>entry1</ns1:li>
<ns1:li>entry2</ns1:li>

</ns1:ul>

</core:v>

• attachment _tm3.py_ added

unittest to reproduce the probem. File also contains partial fix we've applied to get around it

• status changed from new to accepted
• version changed from PyXB 1.1.3 to PyXB 1.1.4
• milestone changed from PyXB 1.1.4 to PyXB 1.1.5

Thanks; will look at this soon.

[Peter A. Bigot]

• status changed from accepted to closed
• resolution set to fixed

Fixed in commit below. In fact, the output of your test case is the correct output; your "should produce" is missing the namespace qualifier on the inner elements (since PyXB does not preserve the default namespace declaration that was in the original element).

Thanks for the example.

trac/155: Namespace name assignment fails on xs:any type

Namespace mappings should be preserved when a DOM object is being
deep-cloned to convert it from one implementation to another. This patch
also permits re-declaration of a namespace with the same prefix.
