What regular expression engine is used by default

问题:

I keep trying to find an online regular expression checker to use with web_reg_save_param_regexp but no joy. What RegEx engine is LoadRunner 11.52 using?

It looks to be some variant of Perl.

回答1:

In LoadRunner we use this: http://www.pcre.org/

Thanks, Boris

This article suggests that the author is using http://rubular.com/ to test his web_reg_save_param_regexp, suggesting that it's likely PCRE (at least partly implemented).

A great PCRE checker is http://regex101.com.
