[xquery-talk] xpath default namespace

[Ghislain Fourny]

Hi Leo,

I'm glad!

Should this happen, I guess you could add a filter using an XPath function
to test for the namespace of the name of the selected element.

https://www.w3.org/XML/Group/qtspecs/specifications/xpath-functions-30/html/Overview.html#func-node-name
and
https://www.w3.org/XML/Group/qtspecs/specifications/xpath-functions-30/html/Overview.html#func-namespace-uri-from-QName

You can test for the absence of namespace easily.

There may be even shorter tricks, I wouldn't be surprised if Mike got
something out of his magic hat :-)

Kind regards,
Ghislain
