Extract a single String from an array of items

Question

A similar question was asked a few years ago, but the accepted answer is vague at best and confusing at worst.

I'm attempting to pass a number that I've retrieved via Regex from a fetched page as the source of a filter.

Here's the link to my pipe: http://pipes.yahoo.com/pipes/pipe.info?_id=4c087880efe5ef2ea62261ff9e7eee1b

I need to get the emitted value from the loop (which is currently 555) and pass that to the string builder so that it prepends a #; I will then pass that built string as the source for my greater than filter on the item.title of the fetched RSS feed.

Since the loop module outputs an array, I currently can't find a way to connect it to the string builder module.

Answer 1

Within for loop we can either get one String from list of String or we can use split("") method to divide String into words
