Solution 2

This pattern

C#

\<K:\d+\>

will match all tags beginning with "K:" and ending with any number.

@downvoter: Thank you! What is wrong with this answer?
It is the same regex pattern as solution 3.

Thank you Matt!

Solution 1

If all tags are the same (<k:number xmlns:k="#unknown">) you can match with \<k:\d{1}\> where:
\< matches exact <
K: matches exact K: (although you might have to escape : too)
\d{1} matches exactly one number
\> matches exact >

If this helps please take time to accept the solution. And next time look for the solution, there are sites that help you create your own regexes without any foreknowledge.

Thank you.
