Matching multiple strings from a file

[gwigg]

Hi, I am trying to match multiple strings per line from a file and extract them into an array. Apparently the first match is assigned $1, how do I know what the last match is ie $last?? I would like to set up a for loop to enter these values into an array: psuedo code below to extract all html tag per line in the file master, array is mastertags:

while (<$master>)
{
$_=~/(<.*?>)/g;
for (my $i=1; $i <= last value; $i++)
{
$mastertags [$x]=$i;
$x++;
}
}

The value of $1 changes dynamically with each match found. In your case, though you are using /g option, you are not using a loop to parse through each match and end up getting only the first match in each line. You can try this:

my $m;
while(<>) {
  push @mastertags,$1 while(/(<.*?>)/g) ; ## push all the matches into array
  $m=$1;      ## holds the string matched
}
print "last string matched:$m\n\n";  
print "$_\n" foreach(@mastertags);
