Seth,
Thanks for the tip. I will adapt it and give it a try. I will find the
URL page. Then check to see if this is a NOT FOUND page (custom tag call)
and then start getting the other pieces of data I need (custom tag call).
Phil

Here's an example of how you would do something like this with a custom tag.
This custom tag would take 3 required attributes, "URL", "Find", and
"StringLen"... By the way, it's something I just threw together quickly, so
no guarantees that it is error-free.. And it would need lots of
error-checking in place before being ready for prime time.. But it should
give you an idea of the principles involved.
<!--- Get the target page --->
<cfhttp url="#Attributes.URL#" resolveurl="no"></cfhttp>
<!--- Use regular expression to exclude any HTML Markup --->
<cfset GrabbedPage = REReplaceNoCase(cfhttp.filecontent, "<[^>]*>", "",
"ALL"))>
<!--- Find text passed in via custom tag attribute "find" --->
<cfset StartPosition = FindNoCase(Attributes.Find, GrabbedPage)>
<!--- Return "Stringlen" number of characters starting with "find"
position --->
<cfset GrabbedPage = Mid(GrabbedPage, StartPosition,
val(Attributes.StringLen))>
<!--- Returned parsed text to the calling page --->
<cfset ThisTag.GeneratedContent = GrabbedPage>
Hope it gets you headed in the right direction.
Take care,
Seth
