change latex output with csquotes

Hello all,

could anyone help me create a script to change Pandoc's latex output?
I have no experience with Haskell/functional languages and have no
clue of how to do this.

I posted a question explaining my situation here:
http://tex.stackexchange.com/questions/52929/how-to-fix-kerning-of-comma-colon-after-quotes

Basically what I want is to substitute occurrences of `\enquote{bla}
\autocite{key}` in the generated Latex file by `
\textquote[\autocite{key}]{bla}`.

The pairs of `\enquote \autocite` commands occurs when my Markdown
file has something like `"bla" [ <at> key]`, so I think its possible to
create a rule in Pandoc to check for quotations followed by references
and output the correct format.

Thanks for any help, and congratulations for this amazing program,
D.
