Question

Hi,

I've tried many hours with regexp to find out some chars from a topicname. My problem:

• Every topicname ends with "Start"
• I search the String before Start ex: (BlAStart -> i need only BlA for a nested search)
• $pattern looks only in the content of the site, and there the topicname is not available
• there is any pattern for the variable $topic?

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

You can use a SpreadSheetPlugin formula to strip off part of a topic name. Example:

• This topic: HowToGetStringFromTopicname
• Stripping "Topicname": HowToGetStringFrom

If you use a CALC in a nested search you need to escape the percent sign so that CALC evaluates once per hit. Example: format="$percntCALC{$SUBSTITUTE($SUBSTITUTE($topic-XXXX, Topicname-XXXX,),-XXXX,)}$percnt"
