XML: Finding nodes by name

Here are the goods:

function selectSingleNode(node, name) {
	for (i = 0; i < node.childNodes.length; i++) {
		if (node.childNodes[i].nodeName == name) {
			return node.childNodes[i];
		}
	}
}
function selectSingleNodeValue(node, name) {
	var selNode = selectSingleNode(node, name);
	return selNode.firstChild.nodeValue;
}
function selectSingleNodeAttribute(node, name, attrib) {
	var selNode = selectSingleNode(node, name);
	return selNode.attributes[attrib];
}

Usage is simple:

//Returns the child node you're looking for
selectSingleNode(parentNode, "Node To Find"); 

//Returns the value for the node you're looking for
selectSingleNodeValue(parentNode, "Node to Find");

//Returns the attribute in the node you're looking for
selectSingleNodeAttribute(parentNode, "Node to Find", "Attribute To Find");

Use them as an Include file whenever you're working with XML. It makes working with XML a little easier.
