Hello joshywashy,

Without <code>...</code> tags around your data, we can only guess at how it’s formatted. If each each record occupies a separate line, like this:

0x0 in mmgsdi_evt_cb mmgsdi X mmgsdi Y
0xd in mmgsdi_evt_cb
0x1a in mmgsdi_evt_cb
...

then your approach should work fine (once the syntax error is fixed, of course). But if, as I suspect, the data is all on one line, then you need a more sophisticated strategy. Here is one approach:

#! perl
use strict;
use warnings;

my ($process) = <DATA>;     # slurp in all the data at once

# Use a look-ahead assertion
while ($process =~ /(0x[0-9a-f]{1,2})(.*?)(?=0x[0-9a-f]{1,2}|\Z)/gi)
{
    my ($hex, $text) = ($1, $2);
    print "Match found: $hex$text\n" if $text =~ /in mmgsdi_evt_cb/;
}

print "Finished\n";

__DATA__
0x0 in mmgsdi_evt_cb mmgsdi X mmgsdi Y 0xd in mmgsdi_evt_cb 0x1a in mm
+gsdi_evt_cb 0xe in mmgsdi_evt_cb 0xf in mmgsdi_evt_cb mmgsdi Z 0x13 i
+n mmgsdi_evt_cb mmgsdi Z mmgsdi Z

Output:

15:31 >perl 882_SoPW.pl
Match found: 0x0 in mmgsdi_evt_cb mmgsdi X mmgsdi Y
Match found: 0xd in mmgsdi_evt_cb
Match found: 0x1a in mmgsdi_evt_cb

Match found: 0xf in mmgsdi_evt_cb mmgsdi Z
Match found: 0x13 in mmgsdi_evt_cb mmgsdi Z mmgsdi Z

Hope that helps,
