Richard - the html entity that didn't "convert" was the quot, starting with

Jim - so you are suggesting a function to convert all possible entities for
a text chunk:
function convertHTMLEntities theText
replace """ with quote in theText
replace "whatever" with "Ç" in theText
...
...
return theText
end convertHTMLEntities
Actually I tried this with the text of your original email, using two
fields and a button with this script:
on mouseUp
put htmlTextToText(fld 1) into fld 2
end mouseUp
function htmlToText pHtml
set the htmlText of the templateField to pHtml
return the text of the templateField
end htmlToText
In field 1 I had:
-----------
I'm reading the HTML text of a web page and parsing it. Some of the text
that I'm parsing contains (") - braces not included.
What runrev function do I use to convert that HTML text to the double quote
(") character?
There will be other characters that I also need to convert, such as
(Björnke).
After reading and parsing the text, I'll be loading a DataGrid.

After running it through the function I get:

The htmlText property is designed not to be true HTML, but to be the one
way you can represent the contents of fields using ASCII characters with
complete fidelity. HTML conventions were adopted for this because of
their simple, extensible nature, so while the name "htmlText" often
conjures up all sorts of web expectations it wasn't designed to fulfill,
when it comes to providing an SGML-like representation of anything you
can do with Rev fields it generally works like a champ.
As Jim noted, there are some things you can do in HTML that aren't
supported by Rev fields currently, so those will fail when attempting to
use htmlText as a generic HTML-to-text converter. But you'd be
surprised at what you can do with it, often including many Unicode
entities as well now that Rev supports Unicode.
Try out the htmlTextToText function above and let me know where it
doesn't work for you for anything you can display in a Rev field.
