Sorting XML data ??

[wingnut144]

I have the following XML file:

<?xml version="1.0" encoding="utf-8"?>
<class>
<sdate>9/10/07</sdate>
<special>1,2</special>
<inst>Max Callao</inst>
<sdate>10/22/07</sdate>
<special>1,2</special>
<inst>Max Callao</inst>
<sdate>11/26/07</sdate>
<special>3</special>
<inst>Max Callao</inst>
<sdate>1/28/08</sdate>
<special>1,2</special>
<inst>Max Callao</inst>
<sdate>3/10/08</sdate>
<special>3</special>
<inst>Max Callao</inst>
<sdate>4/21/08</sdate>
<special>1,2</special>
<inst>Max Callao</inst>
</class>

And am displaying it with the following Coldfusion code:

<cffile action="read" file="C:\Inetpub\wwwroot\SalleBoise\sb1.xml"
variable="xmldoc">
<cfset mydoc = XmlParse(xmldoc)>

<cfset mydoc_stuff = XmlSearch(mydoc, "/class/sdate")>
<cfset cl_inst= XmlSearch(mydoc, "/class/inst")>
<cfset cl_spec=xmlSearch(mydoc, "/class/special")>

<cfset CurrDate=dateformat(now(),"mmmm d,yyyy")>
<!--- Starts off the inital item count --->
<cfset icount=1>

<div align="left" style="margin:0 auto;">
<cfloop index="mydoc_item" from="1" to=#ArrayLen(mydoc_stuff)#>
<cfset mydoc_data = mydoc_stuff[mydoc_item].XmlText>
<cfset mydoc_inst= cl_inst[mydoc_item].XmlText>
<cfset mydoc_spec=cl_spec[mydoc_item].XmlText>

<!--- Find the number of days between the start of the session and the
current date --->
<cfset temp=datediff("d",mydoc_data,CurrDate)>
<!--- Send end date for classes, calculated by adding 23 days to start
of beginning of class --->
<cfset temp2=dateformat(dateadd("d",23,mydoc_data),"m/d/yy")>
<!--- Check to see if date of classes are more than 7 months out, or
are more than 5 days (based on class ending date) in the past, if so,
don't display --->
<cfif (datediff("m",CurrDate,mydoc_data) gte 7) or
(datediff("d",temp2,CurrDate) gte 5)>
<cfelse>
<!--- If class date is more than 23 days old, mark as 'not available'
--->
<cfif temp gt 23>

I would like to find a way I can add an additional date at the bottom
of the xml file, and still have the dates sorted correctly. I was
told about XSLT, but since I need the Coldfusion part of the code to
remain, I'm not sure how I can 'sort' the XML file before its looped
over by the Coldfusion.

Does anyone have any suggestions?

Thanks!
