Hi.
I'm trying to build a html analyzer that looks at natural words in html text.
I'd like to build a routine that walks through the HTML character by

the first " and ' is no problem, but after that, the escaped " and ',

Renee,
I agree with the previous post - what you want to do is non-trivial.
However, to address your question: one approach is to create a single
quote flag (sqf) and a double quote flag (dqf). When you encounter
the first quote, set that flag. When you encounter the second quote
of the same type, clear the flag. At the end, both flags should be
clear, or the html is mal-formed. You can also get more sophisticated
and verify that you do not encounter a single, double, single
sequence, or a double, single, double sequence. That gets more
involved by remembering which quote was first, second, and third -
third should be same as second, for example.
