How can I match the three words in the following string with a Perl compatible regular expression?
word1#$word2#$word3
I don't know the actual words "word1, word2 and word3" in advance. I only know the separator, which is #$.
And I can't use the word boundary as I have a multibyte encoding. This means for instance that the string can contain non-ASCII characters like umlauts which are not detected by the \w control character.
Try this regular expression:
/(\w+)#\$(\w+)#\$(\w+)/
Edit After your provided us with more information (see the comments to this answer):
/((?:[^#]+|#[^$])*)#\$((?:[^#]+|#[^$])*)#\$((?:[^#]+|#[^$])*)/
