#Regular expression not case sensitive mod
For example, say you need to create a SIT for an eight digit license number where the last digit is a checksum digit that is validated using a mod 9 calculation. In the above example, the above pattern /cow/i in simple terms means: / Marks the start and end of the pattern. For the beginners who have not heard of it, the regular expression is the multi-purpose pattern matching thing used to compare, replace, or search a string. If you need to run a checksum on a digit in a regular expression, you can use the checksum validator. Finally, we have the dreaded regular expression.
How did I miss that? I have been doing regular expressions for a long time now and this one has escaped me. More information on regular expression validators Checksum validator. I thought the only way to work around this was to either put all characters in regular expression (ie ), but it turns out there is a flag for performing a case-insensitive search: I thought the only way to work around this was to either put all characters in regular expression (ie a-zA-Z), but it turns out there is a flag for performing a case-insensitive search: (i) How did I miss that I have been doing regular expressions for a long time now and this one has escaped me. When testing a case-sensitive Regular Expression (RegEx) definition, it matches lower and uppercase text strings as if the Regular Expression is case-insensitive. Example: For payload having value ' AaaBbbCcc' (Value within quotes) below are the scenarios and result. The problem with that though is that there is no "NoCase" type methods built into the Java string (except for String::equalsIgnoreCase(), but that doesn't use regular expressions). Regular Expressions are not case sensitive great kc. Mule Expression Language leverages capabilities for regex functionality, To enable case insensitive matching prefix regular expression with (i) syntax as in the below examples. We have all used:Īs you well know (if you follow my blog), I am a huge fan of using the Java String methods for regular expression find and manipulation. I ripped a version of the block and changed it so it wasn't case sensitive, it's name RegExCaseSenstive (ah time for me to buy a dictionary) you can find it at.
As you all know, in ColdFusion, when you want to do a find or replace with no case sensitivity, you just append "NoCase" to the method call. I think we use the /i flag on the regex block which causes it to ignore case.
