Hi, I’m extracting text from an email to send tweets. (Each tweet is about a new publication in a journal.) Problem is, each email might contain multiple matches to the pattern I’m looking for. So, I used “Text to Line-Item” to split the email into lines, and search each line for the pattern. So far, so good. E.g. I have an email that gets split into 5 lines, and of those 5 lines, 2 contain the pattern. All five lines are then output as line items. Like so:

0:

    _matched: false

1:

    0: title of first publication

    1: author of first publication

    2: DOI of first publication

2:

    0: title of second publication

    1: author of second publication

    2: DOI of second publication

3:

    _matched: false

4:

    _matched: false

This is where things get difficult. I want to build a tweet from each line item that matched the pattern.  But when I put in a step 4 to do this, I’m not offered the right inputs. What I get instead of items 0-4 is a dropdown showing me either “Output” (whose value is the whole array given above) or “Output 0” whose value is a string containing the 0 values for each of the five items, separated by commas!! I’m not offered an input *for one item*. So I can’t iterate through this list of items to do anything useful.

I’d be super grateful for any suggestions. (Adding a code step isn’t an option as I don’t know Python or Javascript.) Thanks!
