Just lurking and I saw this. A simple technique might be to insert a
new line before each href then use grep and cut. e.g. open it in vim
and do:
:%s/href=/^Mhref=/gc
:%s/HREF=/^Mhref=/gc
(where ^M is ctrl+v followed by the return key)
Then
grep href filename.html|cut -d '"' -f 2
and optionally
... | sort | uniq
There might be some way to do a case insensitive find and replace in
vim, but I don't know it of the top of my head.
