I would like to parse a scalar to see if it contains certain information that I am looking for. For example, each scalar may/may not contain the following information [x()]. In addition, the [x()] may appear more than once. Therefore, I need to loop through the scalar.

For example, the following scalar may exist: 

$scalar = "anyfile_[w(one|two|three|four)].txt";

[download]

Whenever the [x()] appears, I need to be able to look at the information within the brackets. Depending on the value of "x", I need to perform a specific operation with the items that appear in the "()." As of right now, I am having a hard time with the loop and the regular expression. I really need some help with this.

How do I loop through the scalar and find the [x()] and extract the "x" and "()" information? What if there are more then one [x()]?

Any help and/or advice would be greatly appreciated.
