Re^2: how to split a string at [ ?

Hello!

The text before the equal sign can differ from BCInletTemperature. It can be another word. But the word will be always low/capital charaters without a blank.

Can I get this with the above too?

Regards, blaui

Yes, see perlre on how "alternations" work: `$temp =~ /(BCInletTemperature\|someOtherTemperature\|aThirdTemperatu +reName) = ([\d.]+)\[C\]/ or die "Invalid temperature format in '$temp'"; my( $temperatureType, $temperatureValue ) = ($1,$2);` [download] But maybe you want a more generic parser that will capture any word on the left hand side of the "=" sign and any number on the right hand side. Then you can use the `\w` character class or the `[A-Za-z]` character class (again, see perlre) for matching any word on the left hand side: `$temp =~ /(\w+) = ([\d.]+)\[C\]/ or die "Invalid temperature format in '$temp'"; my( $temperatureType, $temperatureValue ) = ($1,$2);` [download]	[reply] [d/l] [select]
