RE: Stripping words from a string
Though s(world .. worked w/o /, it should be written s/(world | how )//gi; s/\b(world|how)\b//gi; The \b is a word boundary, which is going to work as expected more frequently. The first example doesn't work if the word is followed by a punctuation mark. The second example doesn't get rid of the space, which is fine for HTML, but not for other uses. I would suggest $string =~ s/ ?\b(world|how)\b//gi; but I'd love to hear further suggestions. /\/\ark -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If you're removing the word at the beginning of a sentence, TRAILING spaces must be removed, and the next letter capitalized! If you're removing the word in the middle or at the end of a sentence, LEADING spaces must be removed.

RE: Stripping words from a string
Put the string in $_ and with s(world |how )//gi; If you don't take out a space then you get a couple of spaces: Output(no space part of check (world|how): Hello are you? Output(w/ space part of check above): Hello are you?

Re: Stripping words from a string
s(world | how)//gi works for the same reason
s{world | how}{}gi works
The first and second set of regex delimiters do not have to be the same, so
in the first instance, the first set of delimiters is () and the second set
is //.

Subject: Stripping words from a string
Hey all,
Just wondering how I would go about stripping words from a string.
If I have a string that has the following...
$string = Hello world how are you?;
How would I go about stripping the words 'how' and 'Hello' ignoring case
each time?
Would it go something like the following...
$string =~ s/.*hello/how\//gi;
Thx,
Da
