Thanks, it works. But now I have another problem. Some third-party
library generates XML elements, which are added to my XML document. Each
element contains _explicit_ namespace declarations. When document is
serialized it looks like I posted earlier (see below). The problem is
that even if I add namespace declaration to the top-level element,
resulting document looks like this in serialized form:
<ns:root xmlns:ns="urn:ns1" xmlns:ns2="urn:ns2">
<ns2:child xmlns:ns2="urn:ns2"/>
<ns2:child xmlns:ns2="urn:ns2"/>
</ns:root>
Is there any way to automatically force redunant namespace declarations
to be removed from the child elements when they are serialized?

I guess the above result is because of specific normalization /
optimization algorithm - the serialization would need to look ahead
which might not be always possible to produce the form you want. I
don't know if the namespace normalization algorithm [1] for the DOM
Level 3 Document.normalizeDocument() is any different, too. You would
notice descendant elements of <ns2:child> which are in the same
namespace won't get 'xmlns:ns2' attribute.
You could always add the namespace declaration attribute yourself:
root.setAttributeNS("http://www.w3.org/2000/xmlns/";,
"xmlns:ns2", "urn:ns2");
