Plain text from PDF using Air/ActionScript

Is there a way t开发者_运维技巧o extract plain text from a PDF file using ActionScript? If not, can you give me some hints on how it is implemented elsewhere?

I don't think there are any existing actionscript library for parsing/extracting text from PDF's (as it'd be too cumbersome doing that in it). But you can use xpdf, which is implemented in C/C++, which comes with pdftotext.
