Hi Paul,

I am cc'ing this to the lsit as I am sometimes wrong - hopefully the
many who are more qualified will correct me if I have got it wrong.

SORRY - I was a bit terse;
The format statement is described on page 43 (51st page of the pdf) of
the developers guide

Try adding to the collect.cfg file
format DocumentText "This is where DocumentText appears for [dc.Title]

[save file/refreshbrowser - you may have to restart greenstone if you
are using the windows/local library version]

Open you collection in the browser - search for a document with no
text - click the link to the [nonexistant] text - you should see the
testmessage you included
(BTW there is no need to rebuild the collection when editng the format
statements - just save/refresh)

If you see the message then you have successsfully used format DocumentText
You can then play with {If} to make the result conditional on the
presence of text.
I would suggest testing a metadata field {If}{{[Text],,} doesn't
work. [this would require you flagging the pdf files with no text
using a metadata field - pretty easily done either manually or by
modifying PDFPlug - this is assuming that PDFPlug/greenstone doesn't
already have an inbuilt resolution to this problem that I am not aware

Sorry I am being still being pretty terse - if you could give examples
of the start of the doc.xml files for pdfs with and without text I
could probably formulate a better example.

I hope this helps - email me and the list back with responses as most
people run into the same problems.
