Filtering xml data by date range

Question

I have a static xml file with a large number of events and
the dates of those events. I can presently get all of the events to
appear in a Spry table. Can I get only 5-7 events to appear in a
Spry table based on a range of dates (ie. the events that will
happen from today to three days from now)?

You'll need to do something like this:
<script type="text/javascript">
function FixDateFormat(dstr)
// The idea here is to make sure that dates like "08/08/08"
// get interpreted as "08/08/2008" instead of "08/08/1908"
// by the built-in Date object.
if (dstr && dstr.search(/^\d\d\/\d\d\/\d\d$/) != -1)
dstr = dstr.replace(/(\d\d\/\d\d\/)0(\d)/, "$1200$2");
return dstr;
// Create a date object with today's date at midnight.
var gCurrentDate = new Date();
gCurrentDate.setHours(0,0,0,0);
// Create a date that is 3 days beyond todays date. Note that
// this means 4 full days since it includes today.
var gFutureDate = new Date(gCurrentDate.getTime() + (
4*24*60*60*1000-1 ));
function FilterByDate(ds, row, rowIndex)
// The assumption here is that your column name is "date".
var d = new Date(FixDateFormat(row.date));
return (d >= gCurrentDate && d <= gFutureDate)
? row : null;
var ds = new Spry.Data.XMLDataSet( ... );
ds.filter(FilterByDate);
</script>
