Sorry for asking this question again for what must be the umpteenth time but I have a problem with
the g modifier when matching. I have read Newsgroup Postings about this topic including:
"What good is \G in a regular expression?"
Listed below is what I'm experiencing problems with:
$PARSE{"letter"} = "([A-Z])";
$PARSE{"number"} = '(\d{1,2})';$src = "a 1 b 2 c 3";
if($src =~ m/$PARSE{"number"}/sgi)
{
$num = $1;
}if($src =~ m/$PARSE{"letter"}/sgi)
{
$let = $1;
}print "Number: $num\n"; #-->(Prints "1") print "Letter: $let\n";#-->(Prints "b") #(Prints "a") <-> If Letter Matching Comes First then Number Matching # OR #(Prints "a") <-> Without g Modifier
Based on FAQ 6.19, I'm trying to understand why Precedence matters when using the g Modifier when matching
part of a string, even when that string hasn't been modified.
I don't have any problems when using the g Modifier in a Loop, for some reason.
From FAQ 6.19:
The notation "\G" is used in a match or substitution in conjunction with
the "/g" modifier to anchor the regular expression to the point just
past where the last match occurred, i.e. the pos() point.
Thanks in advance. -gohaku
