No, it's better described as: divide the string into a sequence of strings
some of which match the regex and others which don't. Then process all the
substrings in turn, appling the matching-string instruction to the matching
substrings and the non-matching-substring instruction to the others. 

Try:

<xsl:variable name="duration" as="xs:dayTimeDuration"
  select="xs:dayTimeDuration(concat('PT', translate(replace($in, '
([ms])[a-z]+ ', '$1'), 'ms ', 'MS')))"/>
<xsl:variable name="seconds" as="xs:integer"
  select="$duration div xs:dayTimeDuration('PT1S')"/>
