Expression |
(?=([\W]*[\w][\W]*\b))\s(?=\d\.|\d\b)

|
Description |
This RegExp matches a space (" ") character with lookahead condition if there is an ASCII text in front of it and it is followed by a single decimal number which in turn is followed by a dot or nothing. It's useful to seperate scientific notation numbers from a text, i.e. when classifying with the bow toolkit.
[EDIT 18.09.2004] There was indeed an error in the second lookahead. Changed |\b to |\d\b
