Question

There are 2 xml document with different namespaces, e.g.

declare namespace ml1 = "urn:schemas-com:ml1";
declare namespace ml2 = "urn:schemas-com:ml2";

but with same structure.
Can I select some nodes using only these namespaces, without *? I mean something like that:

fn:doc($uri)/(ml1 or ml2):root

Updated:
Thanks. All suggestions work but not useful for me. Because there can be 3 or more namespaces, and xpath expression will be very large. Any suggestions?

Conclusion:
Thanks for the answers. I agree with @MichaelKay that I should process all xml all documents. Problem is solved.

Answer 1

One possible expression is:

  doc($uri)/(ml1:root|ml2:root)

Another is:

  doc($uri)/*[self::ml1:root or self::ml2:root]

In case there can be an unlimited number of prefixes of the form "mlNNNNN"", use:

  doc($uri)/*[matches(substring-before(name(), ':'), '^ml\d+')]
