Assuming what you're actually asking is how to escape any ampersands that are
not part of an existing entity, try this...
REReplace(Text,"&(?!([##A-Za-z0-9]{2,6};))","&","all")
(because any non-entity ampersands must be escaped everywhere, not just in
links)
> Okay, I can usually figure out my regular expressions when needed, but
> this one has me a bit stumped. Basically I have an unknown chunk of
> text in which I need to make sure any URLs are XHTML-compliant...i.e.
> any ampersands are escaped, if not already. I need to be sure to only
> replace within the <a> tags, not the rest of the text, and to not
> replace any ampersands that are already escaped. Anyone want to take a
> stab at it?
