<div>Hi All,</div>
<div> </div>
<div>Following Alans suggestion, I am going to repost the question with some
test cases.</div>
<div> </div>
<div>I am looking for a way to match a string that appears in a comma separated
list. The string may may appear at the start or middle, end or nowhere on a
list. I have stumbled along and made this work in the past, now I am looking for
the clean and proper way to do it.<br><br>One of the unpleasant side effects of
putting a list with alternatives at the start .e.g. '(^|,)' , is that it creates
an undesired capture string. Is it possible to avoid creating the capture
string?</div>
<div> </div>
<div>Test code below. Anywhere where ‘foo’ appears should match but ‘food’
should not match</div>
<div> </div>
<div>foreach $s ('foo,bar,baz', 'bar,foo,baz', 'bar,baz,foo', 'bar,food,baz')
{<br> print "s=$s ";</div>
<div> </div>
<div> my ($match) = $s =~ /some reg expression or perl code
here to match foo/;</div>
<div> </div>
<div> if ($match)
{<br> print
"match=$match\n";<br> } else
{<br> print "no
match\n";<br> }<br>}</div>
<div> </div>
