tHanks for your perl script. What I should have added was that I was
looking for a better way in C. It needs to fit into my ascii-to-markup
program. The function to scotch <TAGS>, </TAGS> is more than a few lines
because of error-checking.
In addition to a C function that would skip BEGIN and END delimiters, like
the one I cobbled together, is one possible with *any* fixed delimiters--
say, 3- or 4- to some reasonable N- characters?
My hunch is NO. Or at least nothing very simply for some small N, >= 7.
(I'm thinking of the java code blurbs that end in something like "//>"
For the php case, I could have used the "<" and ">" delimiters, but
thought better of it.
