"[SOLVED] Using a loop variable within a regular expression?"

Hi there,

I'd like to pass my loop_value into a regular expression (which is in a Crawl Web parameter, which is inside the Loop Values Operator), however replacing my;

.+period-charts.+today.+

with

.+period-charts.+%{loop_value}.+

isn't working. ย Any ideas ย ???

thanks ย  :)

    I beg your pardon Marius.ย 

    It appears that this does in fact work, so long as I don't use the Regex builder / helper within the Crawling Rules of theย  CrawlWeb process node.ย  When I try to include the %{loop_value} within the regex helper, it won't let me <Apply> it because it doesn't like the syntax.ย  I have to do this without the helper, which is fine because it works.ย  ;D
