For one thing, I only want to extract the YY..Y part of the string. The regular expression should contain a statement that identifies the variable of type Y by its adjacency to Z, but only returns the Y.

Actually, I was looking for a regular expression to extract Y...Y (as many consecutive instances of the variable of type Y following Z as there are). Would just =~ /\S+Z(Y+)\g print $1 work (it doesn't in the code). Thanks, Max

Suppose I have strings of the form: xxxxxxxxxxZYYYxxxxxx where x can be any character, Z is some specific character, and Y is a certain character type (i.e. digits) of arbitrarily length. I want to exploit the fact that substring Y...Y always appears after Z, and write a regular expression that...

Thank you. Sorry for the naive question, but if I understand it correctly, the construct ${1} means taking a single instance of the regular expression and assigning it to the substring ${1}?

Basically, I am trying to construct a substitute expression that accomplishes the following: given all occurrences of a certain type of string (for instance, digits), insert some prefix or suffix before or after all occurences. For example, in the string --12***345)))6789?<>, I want to insert...
