 Topic: RegEx for scrambled wordsPosted: 13 April 2005 at 9:20am |

I'm looking for an effective regex to match scrambled words such as: sotfware All I've come up with so far is ((?i)(s[oftwa]{5}re)) but that, will, of course, match "software" as well. Any ideas? |

I can't think of a fix in just one RegEx but you could use a combination of RegEx
((?i)(sf[otwa]{4}re)) ((?i)(st[ofwa]{4}re)) ((?i)(sw[ofta]{4}re)) ((?i)(sa[oftw]{4}re)) which target the scrambled words. Would this work? |

that's what I'm doing now, but for 5 characters, there are a lot of combinations.... I thought it could be done easier...

Dan, With the existing implementation of RegEX, I am not sure this can be simplified. With the standard Perl RegEx, I would use a "NOT" function but that requires "Look Ahead" which I am nearly certain is *not* supported. Regards, |
