Return regex match in Yahoo Pipes

Question

I want to take my 'item.title' string and store a match from a regular expression into 'item.myRegexMatch'. However, it's unclear to me how to achieve this, as all the Regex modules in YP require a "replacement" string. I don't want to replace anything; I just want the Regex match returned. This seems trivial, but I'm fairly new with YP and regular expressions, so hopefully I'm simply overlooking this basic functionality.

Answer 1

Quick answer :

Steps :

1/ Rename module :

[item.title] COPY [item.myRegexMatch]

2/ Regex module :

in [item.myRegexMatch] replace [^.*(YOURREGEX).*] with [$1]
                                   ^         ^

be sure to keep the 2 parentheses indicated in the above line.

Explaination :

The parentheses in the "replace" field define a backreference.

This backrefencere is then used ($1) in the "with" field.
