Re: Find and Replace Macro with regex captured groups in replace text

["F C. Costero" <fj...@gmail.com>]

The problem is the line
oFind.setString(FandR.ReplaceString)

The setString() method takes a string input and doesn't know anything about
the search done with oDoc.FindNext() or regular expressions. You can
perform a global replace that implements your regular expression with
oDoc.replaceAll(FandR)
I tried this for the string budh and got

budh 1P = b[guṇa udh]->b[a+udh]->bodh + a->bodha
which is not exactly what you expected.
I don't at the moment see how to do a local replace but I'm no expert in
such things.
Best regards,
Francis
