Not to be too picky about things, but (imho) there is no such thing as a
'legitimate' angle bracket in an input's Value attribute. According to the
HTML spec, angle brackets, quotes, and ampersands in html tag attibutes
'should be' replaced with their entity references (granted, the angle
brackets are replaced mainly to support old/broken implementations):
http://www.w3.org/MarkUp/html-spec/html-spec_foot.html#FOOT7
Note that failure to escape ampersands in HREF attributes can sometimes
cause unpredictable things to occur in some versions of Netscape-- for
example, a href=somepage.cfm?voltage=100amperage=5 will take the amp
out of context and change the URL, when clicked, to
somepage.cfm?voltage=100erage=5. Which is part of the reason I prefix
all form fields and url parameters with ff. Of course, you could make it
a point to always use amp; when seperating parameters in HREF attributes,
but I personally don't have that kind of patience.
(More suggestions on entity references:
http://www.w3.org/TR/REC-html40/charset.html#h-5.3.2
--not singled out in that doc is apos;, which escapes the single quote
character. For an exhaustive (and exhausting!) list of HTML4 entity
references, see:
http://www.w3.org/TR/REC-html40/sgml/entities.html
)
Also, htmlEditFormat in CF5 no longer eats carriage returns, though it's
still documented as doing so. (Shhh!)
I guess the rule of thumb (according to Daryl) is to always use
htmlEditFormat() when redisplaying user-entered values in HTML form input
fields (when using CF5.)

Daryl,
Well slap my a** and call me Sally. I'm actually doing this with ASP at
the moment, and since it doesn't (to my knowledge) have a fn comparable to
htmlEditFormat, I didn't actually try it with CF first. My apologies to
the group. :)
BTW, the ASP fix is like so: Replace(objRS(body),,amp;) when
writing the KB article body to the textarea. Even with CF, the
htmlEditFormat() fn is a little too several for my purpose, since it also
escapes legitimate and marks, and strips carriage returns.

If you use htmlEditFormat, then the string gt; will be sent to the
browser as amp;gt;
So, it should work just fine. Doesn't it?
If not, please post the snippet in question.
Thanks!

box value)
Use the htmlEditFormat() function around the value.
Value=#htmlEditFormat( someValue )#
This will replace the double quotes with quot;, as needed.
Speaking of htmlEditFormat, here's a question for you. Say you've got a
textarea where users can enter a combination of text and html.
A knowledge
base system, for the sake of argument. The user decides to enter some
displayed code, like this:
This is how to bbold/b a word: lt;bgt;boldlt;/bgt;
The user saves the record, and so far so good. Now comes time
to edit the
article, and here's where it gets ugly... MSIE will display the
lt; and
gt; strings as actual brackets in the text area, so the article now
looks like this in the textarea input box:
This is how to bbold/b a word: bbold/b
and when the user re-saves the article, they of course get switched back
to real brackets.
Any workarounds would be appreciated...
-Ron
