GRR. Command
Get Regular Replace
Intention
GRR. Enables you to replace Parts from Strings which match a regular expression.
What is it really good for?
Using "regular expressions" you can do things that would be difficult to realize in other ways. Take our example. You want to replace all e-mail addresses in a document automatically with the term "[e-mail]. Sounds difficult?
Is easy:
' Use Regular Expression to replace an e-mail adress
: $$NUM=2
: $$MAC=please send an email to info@it-berater.org
: $$MSK=([a-z0-9._/+-]+)(@[a-z0-9.-]+)
: $$REP=[E-Mail]
DBP.Before:
DBP.$$MAC
GRR.$$NUM,$$MAC,$$MSK,$$REP
DBP.After Replace
DBP.$$MAC
END.
Syntax
GRR.[P1],P2,P3,P4
Parameter Explanation
P1 - (optional) NUM/VAR
- Start of Stringscan.
- This can be a Variable containing a number or a number.
P2 - VAR
- Main String. Can only be a Variable of any Type.
- Non-String-Types will be converted to a Textstring.
P3 - VAR Regular Expression. This Variable contains the regular Expression.
P4 - VAR
P2 and P3 must be Variables.
You cannot just write the Regular Expression in the Parameter-Field as the $ and the | are special-characters in Regular Expressions.
Please note that for this command, you have to use the "," instead of the "|" to separate the Parameters.
