Javascript and XPath

In IE once an xml file has been loaded we need to set a property so that XPath can be used:

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("someFile.xml");
xmlDoc.setProperty("SelectionLanguage","XPath");

for other browsers like Firefox we need to set :

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("someFile.xml");
var nsResolver = xmlDoc.createNSResolver( xmlDoc.ownerDocument == null ? xmlDoc.documentElement : xmlDoc.ownerDocument.documentElement);

before calling the evaluate() method.

'selectionsPath' is the xpath expression that we need to form and then for getting the value(s),

//Internet explorer
if (ie)
{
var actions = xmlDoc.selectNodes(selectionsPath);
var i = 0;
for (i=0;i<actions.length;i++)
{
alert(actions[i].childNodes[0].nodeValue);
}
}
else
{
//mozilla
var actions = xmlDoc.evaluate(selectionsPath, xmlDoc, nsResolver, XPathResult.ANY_TYPE,null);
var result=actions.iterateNext();

while (result)
{
alert(result.textContent);
result=actions.iterateNext();
}
}
