Error parsing XML List

Error parsing XML List

Hi,

I'm trying to parse an XML list the way it is shown in the Zoho documentation.  Here is my code:
  1. mapvar = getUrl("http://xxxxxxxxxxxx");
    xmldata = mapvar.toXML();
    strdata = xmldata.executeXPath("/root/value/items");
    xmllist = strdata.toXmlList();
    for each thing in xmllist
        {
            datestring = thing.executeXPath("/items/date/text()");
        }







When I execute, it gives me an error when it gets to the last line.  This is the error:
  1. Execution Failed
    Error details:
    Error occured while executing the script.
    Unable to update variable datestring
What am I doing wrong?  Is there a better way to parse through each "items" XML tag?
