Since JavaScript has no native XPath support: What XPath library are you using? — Tomalak

The xpaht expression you are looking for should be something like:

var path="//product_id[contains('" + result_date+ "',substring-before(date/@value ,' '))]";

Searching any product_id where the substring-before the blank in date is part of your variable result_date.

Most browser support "evaluate" (but not IE).

var nodes=xml.evaluate(path, xml, null, XPathResult.ANY_TYPE, null);
var result=nodes.iterateNext();
while (result)
  {
  document.write(result.attributes.value.nodeValue);

  document.write("<br>");
  result=nodes.iterateNext();
  }

If your "result_date" is a const string. You have to be aware of escaping.

var result_date='2013\\05\\10,2013\\05\\11,2013\\05\\12,2013\\05\\13';
