How you identify a special character? Take for example I would like to split the data based on parentheses.

FIELDNAME.regexIsMatch("(")

The node errors because it is searching for the close parentheses.

I tried using the ASCII code: FIELDNAME.regexIsMatch("/050")

The node doesn't error but it is not identifying the parentheses.

I'm also seeing a problem with $.

I can replace "(", ")", and "$". I'm starting to notice I cannot use those three symbols with regexIsMatch.

The problem here is that (, ) and $ are all special characters as defined by a language called Regular Expressions. See http://en.wikipedia.org/wiki/Regular_expression for more information.


If you have ( as a delimiter, and you wish to identify a string matching it, the syntax is:
result = regexIsMatch("StrngtoSearch" , "//(" )
ie, "//" escapes the special character and allows it to be treated as a normal character.

Attached is a graph that shows a very basic example for using special characters in regular Expression matching.
