Hi,Is it possible to make a regular expression which matches only part of a string. For example: testRegex | toSearch matcher doesMatch match1 match2 numMatches |
toSearch := 'value: 6474 mm'. matcher := RxMatcher forString: ' (\d+) '.
doesMatch := matcher matches: toSearch. numMatches := matcher subexpressionCount.
match1 := (matcher subexpression: 1). match2 := (matcher subexpression: 2).
self halt.which results in: doesMarch = false
numMatches = 2 match1 = nil match2 = nilHowever if I replace the regular expression with: '.* (\d+) .*' so the whole string is matched I see
doesMarch = true numMatches = 2 match1 = 'value: 6474 mm' match2 = '6474'I can always pad my sub-matches with '.*', but I wondered if I'm missing a trick to make the Regex work with substring matches
'(\d+)' asRegex search: 'value: 6474 mm';
