use comm command with regular expression

[e-letter]

Readers,

File 1 contains data:

/some/text/abcd.xyz

File 2:

abcd.xyz

The manual does not seem to indicate that regular expressions can be
used with 'comm'. The task is to be able to compare file1 to file2
using a regular expression as a criterion for comparison, such as:

*cd.xyz

Then create a new file 'file3' that contains only those lines that
satisfy the regular expression, but must contain the same format style
as in file1.

Any help please?

Thanks in advance.
