Robert:
(<a href=")[^"]+(") seems to work when I replaced the " with <@DQ> to
satisfy the <@REGEX EXPR="">
But, it only finds the first URL and not the second URL within the
same text block.
Any idea?
Thanks!

I don't have a working copy of witango studio up at the moment. But I
always first test this stuff in bbedit, or some other text editor
that uses regular expressions. So this may help you, you just have to
translate it to witango regex.
To find the URL, I would use this:
(<a href=")[^"]+(")
This basically says, find all that is NOT a quote in between <a
href=" and "
Now the parenthesis are to specify subpatterns. So I can reuse the
subpatterns in my replacement string. My replacement string looks
like this:
\1somenewurl\2
This tells regex to to replace the entire matched string above with
the first subpattern, then some new text, then the 2nd subpattern.
The first subpattern is <a href=" and the second is just the last
quote. So the new string becomes:
<a href="somenewurl"
The above only works if all your hrefs are quoted, and double quoted,
otherwise you would have to do a much more sophisticated search pattern.

Can REGEX find multiple matching occurrences at one time, or only
find the first match within the text block?
I tried using <@regex expr="(a[[:space:]]href=<@DQ>https?://)(.*)
([\<\/]a[\>])" str="<@COLUMN 'MYTABLE.TEXTBLOCK'>" type=E>
and it matched the beginning of the first URL to the end of the
second URL. How do I make it stop at the end of the first URL?
Thanks!

That is exactly what REGEX is designed to do. It has a learning
curve, but you should seriously dive in, its a great tool to have
under your belt.

how to do that. Any help is much appreciated.
<a href="http://www.websiteone.com/app1.taf?
