Thanks, but I'm not sure that that is material to this issue. Even with regexp, x refers to "extended expression syntax". The extensions differ between regexp and pcre, but not to the extent that it would lead to that syntax error in that pattern (as far as I can see). If the extensions refer to posix extended regex, they shouldn't be needed for the regex in questioni, should they? The error referred to the second capture/replacement index being out of range, so it must have been happy with the first capture. There were three captures in that regex. Clearly, there must be something else that I'm missing. cheers, raf
