I used a lengthy RegEx to find all of the permutations of the word CLIMATE in the New York Times Crossword database. It works, but may be too long: 88 results for regular expression ([CLIMATE])(?!\1)([CLIMATE])(?!\1|\2)([CLIMATE])(?!\1|\2|\3)([CLIMATE])(?!\1|\2|\3|\4)([CLIMATE])(?!\1|\2|\3|\4|\5)(…

[image] DetlevD: Note: In a regular expression the term [CLIMATE] is a set of seven letters. A permutation is a transposition of a given ordered set of elements, in order to create a different ordered set of elements, to give the new order another semantically sense. If there is given a word o…

[image] Rijkstra: That won't work. The seven letters of CLIMATE must be consecutive within a word with no repeats or intervening letters. As I said the long RegEx works. Note that you will find an anagram of CLIMATE within each hit if not the word itself. Ok, as you said, your solution work…

I found out why my shortened RegEx won't work. The site uses Microsoft's .NET which is considered less full-featured that the more standard PERL, PCRE or PHP. .NET doesn't support what I am trying to do at all. I'm hoping Mp3Tag uses one of PERL-based versions. Does anyone here know exactly which…
