Text does not exist as such wthin a pdf page... It's blocks plotted onto a page. Etymon just gives you the option to extract the objects on the page. I gave it a try and ended up writing my own routines to handle the data.
itext (http://www.lowagie.com/iText/) might have what you need or have a look at www.planetpdf.com.
I have spent the last 9 months working on extracting text from pdf (www.idrsolutions.com if you are interested).
