Dear Monks
Problem:
Im trying to pre-compile a couple of patterns (Regular expression) and match it into the given text.
Done so far:
I have tried doing this without pre-compiled regex, which work perfectly
$text="I have a problem with pre-compiled regex";
@words=qw(have regex);
for $a(@words)
{
while ($text =~ m/$a/g)
{
print "Found $&\n";
}
}
Stuck with:
Now when I wanted to pre-compile these patterns (have, regex) and match with $text, I don't get the expected result. I have posted the script which doesn't work, below.
$text="I have a problem with pre-compiled regex";
@words=qw(qr/have/ qr/regex/);
for $a(@words)
{
while ($text =~ /$a/g)
{
print "Found $&\n";
}
}
