I didn't want to start a new thread to ask almost the same question.
I found one formula to remove headers from ABC Converter pdfs, and it works fine. Now I've unearthed an older pdf with a slightly different header and I can't figure out what I need to change to make it work. If someone could help me, I'd be very appreciative.
Here is the new header:
ABC Amber Text Converter Trial version,
http://www.processtext.com/abctxt.html
Here is the header and formula that works:
[Generated by ABC Amber LIT Converter,
http://www.processtext.com/abclit.html]
(<A name=\d+>\s*</a>)?\s*(<[biu][^>]*>)?\s*Generated\s+by\s+(ABC)?\s
+Amber[^<]*(<a\shref=.*?processtext.*?>)?\s*(.*?processtext. *?</a>)?(</
[ibu]>)?\s*(<br>\s*)?
What do I need to change? I have no idea how to create one of these.
