Its nice (?) to know that it’s not only the Pipes’ message boards where things get stripped out.
There should be a [/a] after .*? – change square brackets to angle brackets.
I’ll add another comment a bit later about the pros and cons of the 2 regex expressions.

Declan,
I have a horrible feeling that a closing “a” tag has been stripped from my expression. I will check and report back.
The ${whatever} construct is handy, but it only works in the Regex module.

Thanks Paul! I’ll try to parse that regex this weekend.

For item.content_holder, is this a cleaner version of what I did, or is it a better on that would fail less?

This is really interesting:

In [item.title] replace [Blog\)$] with [${content_holder})]

I didn’t know how to declare variables, or really how to conceive of the scope of how variables would flow withing the Pipes objects.

You could use
In [item.content_holder] replace [(?s)^.*?[^>]+>([^<]+).*] with [$1]
In [item.title] replace [Blog\)$] with [${content_holder})]
Omit all outer []s in the above, and remove the “g”, “s”, and “i” switches.
The second rule removes the need for the Loop and String Builder.
You don’t really need the Regex to remove content_holder. It won’t appear in the RSS output anyway.

Hope that helped and gave you some ideas.

Hi Lisa! Yeah, I’d use it again. I haven’t dreamed up another problem it would solve yet, but I will!

As big of a Pipes fan that I am, all of mine were born pretty much like yours was. As kludgy as I am, I still find the process highly engaging. Would you make another Pipe if you needed to, or is this brain dump your final say in the matter? =]

Thanks! I think I needed those to get the whole string encompassed so that when I did the replace, only $5 was left.

Good stuff! I don’t think the regex was kludgy. (The beginning (.*?) and ending (.*) are probably extraneous, though.)
