Re: Re: old Perl regex problem

     Thank you. I understand better now. I had to look up the "?:" and "?!". I'm going to play with it a little.
     I've also thought of something like /^PH.+[^HI]F?\-000/
     Some examples of the file names are

PH0024080209401400001PH-000
PH0026072913114200001IF-000
PH0029072911352700001AF-000
[download]

I wonder why it worked on 5.6.1? I'll have to double-check that.

`/^PH.+[^HI]F?\-000/` will accept a file called `PHfooIF-000/`. After all, the `.+` can match the 'fooI', the `[^HF]` can match the 'I', and the `F?` matches nothing. Abigail	[reply] [d/l] [select]
