Re: Extracting Strings - Special Casesby Athanasius (Canon)
|on Jan 07, 2013 at 13:35 UTC||Need Help??|
Hello rajkk04, and welcome to the Monastery!
i want to extract only 4 letters (alphanumeric) in the complete text.
Assuming this means: Match the first alphanumeric word of exactly 4 characters appearing between double quotes:
See “Quantifiers” under perlre#Regular-Expressions.
Update: If you need to match strictly alphanumeric characters only (no punctuation characters), change \w in the regex to [A-Za-z0-9].
Hope that helps,
