Ideas for a text "unformatter"

[na_th_an]

For page footers et al, all I can figure out is the use of a regular expressions evaluator and a text replacer. You create a regular expression that fits the format of the page numbers and then use find and replace to eliminate the text which is equal.

Yes I considered regular expressions, the problem is implementing them in QB...
Maybe the solution would be running first SED and then my progam, as SED does'nt provide an easy solution to selective end-of-line removal.
