Well, I could consider the option to add by myself a function not implemented , in case of extremely rare kind of documents , never explored before , but this is not the case .... with plenty of libraries available for the (probably) most used format of the world ...
And with TEXT I mean TEXT , not images or whatsoever ...
I don't ask HOW to do , I'not a newbie, but which library is working ...
From the links received, now I'm wondering if to change the question in : is there any library working ?
