It is nothing.
This is not good code. I haven't really looked through it lately. Don't learn
programming practice from it.
With that said, I think this shows how to use find to remove tags and (optionally)
content
<cfparam name="keepTagContent" default="0">
<cfparam name="tag" default="FONT">
<cfparam name="tstr" default="An example <FONT face='fgfg'>This should
be gone</FONT> This should still be there.">
<cfset findstr="<"&tag>
<cfset endstr="</"&tag&">">
<cfset tstr2=tstr>
<cfset tnext=FindNoCase(findstr,tstr)>
<cfif tnext NEQ 0>
<cfset tnewstr="">
<cfset tstart=0>
<cfset tcRow=1>
<cfloop condition="tstart LTE len(tstr)">
<cfset tnext=FindNoCase(findstr,tstr,tstart+1)>
<cfif tnext NEQ 0>
<cfset tstart=tnext>
<cfset tend=tstart>
<cfset tagend=find(">",tstr,tnext+1)>
<cfset
tagstr=trim(mid(tstr,tnext,tagend-(tnext-1)))>
<cfset tnexttag=FindNoCase(endstr, tstr
,tend+1)>
<cfif tnexttag NEQ 0>
<cfset tend=tnexttag>
<cfset
tfoundstr=mid(tstr,tstart,tend-(tstart-1)+(len(endstr)-1))>
<cfset tcRow=tcRow+1>
<cfif keepTagContent eq 0>
<cfset
tstr2=replace(tstr2,tfoundstr,'')>
<cfelse>
<cfset
tstr2=replace(tstr2,tfoundstr,'#mid(tfoundstr,len(tagstr)+1,(len(tfoundstr)-len(tagstr))-len(endstr))#')>
</cfif>
</cfif>
<cfelse>
<!--- aint no more footnotes, so we are done
--->
<cfbreak>
</cfif>
</cfloop>
</cfif>
<cfset result=tstr2>
<cfoutput>#tstr#<br>
#result#<br></cfoutput>

No CFMX upgrade for a while unfortunately, will look into the refind (if
I get time!)
Cheers to Neil, Jerry and Ben, much appreciated

The easy answer (for me) is to upgrade to CFMX, which allows
"non-greedy" matches, which are intended to do exactly that.
If you really need to do this, I'd use refind() to locate each instance
of the beginning and ending tags and loop over that, removing them as I
find them.

: Hi all...
:

was

: Just be aware that if you have a page like
:
: Between <ud_stripout>the waves</ud_stripout> and the shore
<ud_stripout>
: there's a boat</ud_stripout> here.
:
: You'll get
: Between here.
: not
: Between and the shore here.
:
: Because that regex will strip /everything/ between the /first/ open
and
: the /last/ close. Which is why some of us are asking wierd questions
: about it.
