Terry,
Something like this should work. Note this is not tested. Here's a
little explanation too. The '.' matches any character as you know and
the '*' says any number of those any characters. The key is the '?'
after the '*' which makes the match "non-greedy". Normally the '*'
matches as many characters as it can and still satisfy the regular
expression. Adding the '?' makes it match as few characters as it can
and still satisfy the expression.
#!/usr/bin/perl
while (<DATA>) {
push(@files, /(BEG.*?KEYWORD.*?END)/g );
}
print $_ . "\n" foreach (@files);

Subject: [Perl-unix-users] Regex question
Can someone point out what I appear to be missing ? I am trying to
extract BEG ... KEYWORD .. END from the DATA string below:
I only want the BEG to END portion where KEYWORD is in between. As
is..... I get the entire string.
<script>
#!/usr/bin/perl
while (<DATA>) {
push(@files, /(BEG.+KEYWORD(?:(?!BEG.+KEYWORD).)*END)/g ) ; } print $_ .
"\n" foreach (@files);
__DATA__
BEG blah blah blah more blah ENDBEG blah blah blah more blah KEYWORD END
</script>
Terry
