Have you considered using '$2$3' as the outer replacement?
But I’m wondering whether the regex is really intended as it is written
here. If you are trying to replace repeating groups of (,(\d{3})) with
each $2, it should be more like (,(\d{3}))+ instead of (,(\d{3})+…)
You can’t, however, refer to repeated occurrences of a captured
substring. $2 will give you only the last, iirc.
If there were lookaheads in XPath 2, it might be feasible for repeated
,\d{3} groups.
Maybe you should just tokenize or xsl:analyze-string your lines on a
tab, determine whether a given token represents a number and if it does,
strip all commas. Then reassemble the line if needed.
