Classification Rule Builder: Force output to lowercase (RegEx)

Avatar

Community Advisor

13-10-2016

Some versions of Regex include a "\L" syntax that allows a string to be forced to lowercase.

 

This would be really useful as at the moment the classification that is created reflects the case of the original input - which can lead to messy looking values in reports.

 

For example...

 

Input value:

website.com/PROMotion

 

RegEx:

^(.+)(\/.+)$

 

Mapping rule:

$2

 

Results in:

"/PROMotion" appearing in the report, where as I would prefer "/promotion" to appear in the report

 

Note: this is about the output, not the matching criteria - aware we can already do case insensitive matching

@AndyW - Actually no, we cannot do case-insenstive matching.  CRB is case-sensitive. 

 

A couple years ago when CRB first came out, the regex tester popup (where you enter in the regex and a single key to test against) was case-insensitive.  But when you go to the rule tester (where you enter in multiple keys to show classification results), that was case-sensitive.  And if you actually run the rule, the actual process is also case-sensitive.  

 

This was a bug I reported to Adobe when it first came out.  I asked them if they could either make a flag to specify case-senstivity, or failing that, make everything case-insensitive. Their reponse was to make everything case-sensitive.  Which really sucked.  Because now I have to do dumb workarounds for values like this: ^[Ff][Oo][Rr][Mm]$
