Here is a sample with JScript using MSXML 3:

var xmlDocument = new ActiveXObject('Msxml2.DOMDocument.3.0');
xmlDocument.async = false;
if (xmlDocument.load('test2007080802.xml')) {
   xmlDocument.setProperty('SelectionLanguage', 'XPath');
   var nodes = 
xmlDocument.selectNodes('headerDISCREPTABTYP/DISCREPTABTYP[contains(discrepancytype, 
"BELONG") and contains(empcode, "114351")]');
   alert('Found ' + nodes.length + ' node(s).');
}
else {
   alert(xmlDocument.parseError.reason);
}

For your XML input the alert shows that two nodes are being found.
