Re^2: (Solved) Extracting sometimes null string from text variable

I like your philosophy.
There is nothing wrong with my posted code in terms of execution efficiency or understand-ability in terms of my application.

I see how to do it shorter.
The solution of using \h gives me pause because it is obscure.
I wanted to know about this shorter method.
But that doesn't necessarily mean that I will use it in the production code.

Update:
My code snippet is just a very, very minor part of a Web Automation program which visits about 100K+ links. I am working with the webmaster for this site and we are developing new features. With our new features, I will only have to visit a max of 2K max web pages (Not 100k). In general a peep-hole optimization for a few lines doesn't matter much. The huge qains have to do with algorithms adjustments. That stuff can yield 50:1 or even 200:1, a huge performance increase.

The solution of using \h gives me pause because it is obscure. The list of character class escapes in perlre could be improved by better grouping of related character classes.	[reply]
