Yes; but it is not practicable with iText. You could, however, as long as the
PDF is printable, use the following procedure:
1. Print to a PS file.
2. Scan the PS file from step1 above, dropping all lines that do not end
with Tj or TJ.
3. Use a regular expression (together with Substitution or Match) to
extract the instances of "text fragment" from within multiple instances of "
(text fragment)Tj", printing the resulting text fragments to STDOUT.
Bruno has given an excellent example of why you should not expect the resulting
output to make sense, i.e., the text fragments may not appear in the order in
which you'd like for them to appear.
Cheers,
Bill Segraves
