Bug 3811 – XML serializer does not support namespaces

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: DOM

[Henri Sivonen]

Steps to reproduce:
1) Load an XML document that uses namespaces. In particular, there should be an
xml:lang attribute.
2) Add some namespaced stuff to the DOM tree using the NS-aware DOM level 2 API
calls.
3) Use the setAttributeNS and setAttribute methods to attempt to modify the
xml:lang attribute.
4) POST the modified doc to the server.

Actual results:
The serialization does not have namespaces at all and the local names are used
as element and attribute names. The element that had an xml:lang attribute may
now have two (!) attributes named lang making the serialization ill-formed!

Expected results:
Expected a namespace-savvy serializer to be used. That is, expected the
serializer to preserve (ns-URI,localName) pairs by synthetizing xmlns attibutes
and prefixes if necessary. Expected residual prefixes and xmlns attributes to be
used as hints of preferred prefixes when possible.

Expected DOM Level 1 tampering with the xml:foo attributes to get the namespace
right. (IE does not do namespaces or DOM Level 1 but does have sane behavior
with DOM Level 1 and xml:foo attributes.)

Additional info:
I had to fall back to RSS-style non-XML-ish language metadata, which is uncool.
