FF / Chrome的xpath查询

Question

I have a query that works fine in IE, but I can't seem to get it to run correctly in FF or Chrome.

...
<calendars>
<totalDates>2</totalDates>
<date>
    <dayDate>2013-12-03</dayDate>
    <intervals>
        <intervalName>AM</intervalName>
        <intervalName>PM</intervalName>
    </intervals>
</date>
<date>
    <dayDate>2013-12-04</dayDate>
    <intervals>
        <intervalName>AM</intervalName>
        <intervalName>PM</intervalName>
    </intervals>
</date>
</calendars>
...

To get the intervalName nodes in IE for "2013-12-04" I use:

intervalNodes = resp.documentElement.selectNodes("/calendars/date[dayDate='2013-12-04']/intervals/intervalName");

How do I get the intervalName nodes in FF/Chrome?

Thanks for the help, Scott.

You can use http://www.w3.org/TR/DOM-Level-3-XPath/xpath.html#XPathEvaluator eg

  var result = resp.evaluate("/calendars/date[dayDate='2013-12-04']/intervals/intervalName", resp, null, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null);
  var node;
  while ((node = result.iterateNext()) != null)
  {
    var name = node.textContent;  
  }
