First this: of which type is the writer object in your code snippet?
If it's of type PdfWriter, you're doing it wrong! If it's of type
PdfCopy or PdfSmartCopy, please read on.
There are different ways to solve your problem.
You could use iText to parse every page and to omit that page if some
specific text is present.
Of course: this will only work if the text is always identical and
doesn't accidentally appear on a page you want to keep.
You could ask the people who create the pages to add an annotation on
all the disclaimer pages.
Then you can omit all pages that contain this annotation.
You could ask the people who create the pages to use "Marked Content" so
that you know which content is part of a disclaimer. Now you can create
your own parser (similar to what we did with the OCGParser class) and
remove all content marked as disclaimer (a lot more work and maybe
overkill for what you need).
I'm sure there are other solutions available, but these are the first
three that come to mind.
