Retrieve "text" from a Safari web history.

Hello,

Basically a friend of mine lost a big part of his post he did on his blog (long story). He was able to retrieve some from different sources, however there is still some missing.

Actually if I do a keyword search in Safari history I still get link to these non-existing posts, i'm wondering if there is a way I can extract the actual text from my browsing history.

Thank you to anybody who can answer my question.
