Well, this seems to be solved so I should share it. Thanks to those who helped.
This function takes an HTML text string and extracts the first paragraph (i.e.,
the first displayable text string wrapped in P tags). It ignores any images,
headers, empty P tags, etc., and returns only the first actual paragraph. Works
with HTML editors like tinyMCE.
Code is:
<!--- this method returns the first paragraph (wrapped in P tags) in an
HTML string --->
<cffunction name="GetFirstParagraph" returntype="string"
access="public" output="false">
<cfargument name="html_text" type="string" required="yes" />
<cfset
ExtractionString="#reReplaceNoCase(html_text,'<p>([^\w*?])*</p>','','all' )#">
<cfset
ExtractionString="#reReplaceNoCase(ExtractionString,'<p>([\s]|\ )*</p>','','all')#">
<cfset
startExtractPosition=FindNoCase("<p>",ExtractionString)+3>
<cfset endExtractPosition=FindNoCase("</p>",ExtractionString)>
<cfset
ExtractStringLength=endExtractPosition-startExtractPosition>
<cfset
ExtractionString=Mid(ExtractionString,startExtractPosition,ExtractStringLength)>
<cfreturn ExtractionString>
</cffunction>
What a pain that was. Thanks for the help.
