Welcome to Perl!
This is easily achievd in Perl and the script to do this won't be very long but there are a few things you need to learn. These are:
- open a file and read line by line (a solution was shown already in a previous reply)
- use regular expressions to get the named fields (tag/value pairs) out of the line of text. You could also use "split" to first split on spaces to get a list of tag/value pairs and then split on the "=" for each one to get the tag and the value.
- read the data into a hash - find out what hashes are and how to populate them and read from them.
Have a go at a short script. Doesn't matter if it doesn't work at first. Post it here if it doesn't work and you will receive more help. Good luck!
