Actually, even creating the first group is unnecessary. This revision only captures a single group being the parenthesized content of the string.

I hope this helps.

I have an element

I can remove the '(senior)' from the data using
<xsl:value-of select="replace(., '\([a-zA-Z]+\)', ' ' )"/>

which gives me
<Person>Benes , Frances</Person>
but I want just the opposite:
<Person>(senior)</Person>

You can use regular expression groups in XSLT using unescaped parentheses. I hope the example below helps where I wrap the text before, in, and after as three groups. Creating the third group is unnecessary, but I left it in for completeness. You might need something more creative based on what you allow in your input.
