    can you clarify a little bit more?  thanks.


    Add any lines not matching the To and From lines to a new variable.

    <cfset newText="" />

    <cfloop list="#email_list.body#" delimiters="#chr(13)##chr(10)#" index="line">

                      //* replace the whole from line with empty *//

                 <cfif REFindNoCase("From:.*",line)>

                     <cfset from_line = line />

                    <cfset from_line = #REReplaceNoCase("#from_line#", "From:.*", "")# />

                   //* replace the whole To line with empty *//

                 <celsefif REFindNoCase("To:.*",line)>

                     <cfset to_line = line />

                    <cfset to_line = #REReplaceNoCase("#to_line#", "To:.*", "")# />

                <cfelse>

                    <!--- if not removing line add to newText string --->

                    <cfset newText=newText & line & chr(13) & chr(10) />

                </cfif>

    </cfloop>

    <cfoutput>#newText#</cfoutput> <!--- email text without to and from lines --->

    This was truncated when I posted it previously.

    another method to correctly get the content, but a bit tricky. See code below.

    <cfset emailvar = "From: jane doe  Sent: Thursday, September 10, 2009 1:01 PM">
    <cfset fromPos = findnocase("From:",emailvar)>
    <cfset toPos = findnocase("Sent:",emailvar) - (fromPos + 5)>
    <cfoutput>
         between from and to : #mid(emailvar,fromPos+5,toPos)#<br />
    </cfoutput>

    using the findnocase you can get the position and use mid get the characters between the two points.

    You could also use regular expression match lines starting with "From" and containing text that looks like an email address.

    <cfsavecontent variable="emailText">

    Can you provide an explanation, with samples, of what you are trying to do?  Please provide the code you've already tried. Explain what did not work: what was the expected result versus what was the actual result.  Please include any error messages you received.

    Thanks.  I do not know if there is a tag or function that will work.  Basically, I have text email that I use cfpop to pull out the email body


    The text content as follow,  So I want to get the From and the Sent out the this text and save as its own string.  After I save those, I can delete them.

    Thanks.

    Try treating the entire string as a list delimited by chr(13).  Output the first couple of elements.  If they are the To and Sent lines, treat those lines as lists delimited by a colon.  You want listrest().
