Hi,
The script first obtain today´s date in this format 1/2/2013 and stores in DateString variable. Then create a XML document based on this:
<?xml version="1.0" encoding="UTF-8"?>
  Date=1/2/2013
  Date=1/2/2013
  Date=8/4/2013
  Date=9/4/2013
  Date=1/5/2013
  Date=17/5/2013
  Date=27/5/2013
  Date=6/6/2013
  Date=23/6/2013
  Date=6/4/2013
  Date=25/12/2013
  Date=26/12/2013
that i´ve upload to uccx. it uses get XML Document Data function and stores the result in DataResult variable.
if
DataResult == null meets True it makes a call redirect to an extension
if false that means "1/2/2013" was found inside the XML archive and sends to another extension.
The problem i see through reactive debug is that always return null,
In brief: I do not know how to tell using the function "find 1/2/2013 inside Holidays.xml document"
this is what I putted inside get XML Document Data function:
"/descendant::Holidays/child::Holiday[attribute::symbol='DateString']/child::LAST"
