As part of a mammoth custom tag to clean up HTML markup submitted through a form, I'm trying to work out how to escape all ampersands.
Only, of course, I don't want to escape those that are already part of character entities. So I want this: <a href="index.cfm?action=home.welcome&msg=1"> Go to home page & see a message</a> to become this: <a href="index.cfm?action=home.welcome&msg=1"> Go to home page & see a message</a> BUT I obviously don't want this: <a href="index.cfm?action=home.welcome&msg=1"> Go to home page & see a clichéd message</a> to become this: <a href="index.cfm?action=home.welcome&amp;msg=1"> Go to home page &amp; see a clich&eacute;d message</a> Catching numeric entities seems fine - just match against "&[^#]". But what about the named entities? I've got a list of them, but I don't think &[^(#|lsquo;|rsquo;|sbquo;|ldquo;|rdquo;|bdquo;|dagger;)] works, cos the [] character class can only match one character at a time. I'm working my way through Jeffrey Friedl's book on regular expressions, but I've not found a solution yet.
