Is it possible to rewrite the output of this CSV item with Feeds Tamper? I have a feed set up to use the HTTP Fetcher with CSV Parser to download my content from a URL using the Feeds module (7.x-2.0-alpha8+84-dev) and Feeds Tamper module (7.x-1.0). I've mapped out my fields appropriately, but I'm having difficultly with the instance. 

In my CSV source, there's one field where the information source outputs:
[[u'short', u'introduced', u'Solar Energy and Energy Conservation, Bank Reauthorization Act of 1983'], [u'official', u'introduced', u'A bill to amend the Solar Energy and Energy Conservation Bank Act to authorize appropriations for the provision of financial assistance under such Act through fiscal year 1990, and for other purposes.']]

However, I only really need the official title pulled into my content, which should be "A bill to amend the Solar Energy and Energy Conservation Bank Act to authorize appropriations for the provision of financial assistance under such Act through fiscal year 1990, and for other purposes."

Is it possible to rewrite this with Feeds Tamper, and if so, which plugin would you use/how would you set this up? In this instance, I don't believe explode would work because I do not want both items in my content and I would like the brackets '[]' and such removed. If not possible, how would you suggest accomplishing my goal?

I'm happy to provide more information, and I very much appreciate any assistance. tia

Here's the link to the source location. I've limited the results to 1 as to not overwhelm :)
I agree with MPD. Plugins are easy to write. That looks like a serialised Python object. Is that right?

If you want to avoid that then I think your only option is the regular expression tamper. Use a site that allows you too test your expression on your sample string to help get it right while being fuzzy enough to handle edge cases. Here's one.

This seems to work though I'm not 100% on why it only returns the last match so use with caution. Match is in $2.

\[{2}.+?\],\s*\[(u'(.+?)'\,*\s*)+\]{2}

Actually this might be more robust. Match is in $1.

\[{2}.+?\],\s*\[.+\,\s{0,1}u'(.+?)'\]{2}$
