Here's a quick solution built with the "html" procedures in the IPL:
# rmimg.icn
link html
procedure main()
every c := htchunks(&input) do
match("<img", map(c)) | writes(c)
end
It's plain old Icon so you can build it with 'icont rmimg.icn' or 'unicon
rmimg.icn'. It reads standard input and writes the stripped version to
standard output. Example:
rmimg < x.htm >x2.htm
Here's a more general version that strips tags named on the command line:
# rmtag.icn
link html
procedure main(args)
every c := htchunks(&input) do
match("<"||map(!args), map(c)) | writes(c)
end
Usage:
rmtag p img input < x.htm > x2.htm
NOTE THAT htchunks() elides HTML comments.
Note also that rmtag isn't too smart -- a command line argument like "p"
gets <param ...> tags as as well as paragraph tags. (I'll call that a
feature and leave smarter behavior as an exercise.)
p.s.
Thanks to Gregg Townsend for writing the html procs in the IPL.
