Re: [xmljs-users] Is there a good XPath+JavaScript tutorial out there?

I think your implementation is okay, you might just be using the wrong
tool.  I haven't used the xml parsers that are demonstrated in the examples
you've been looking at, but I think the xml for js parsers are more straigt
forward.  I put together this example for you using the labels xml example.
You can access it at
http://millstone.iodp.tamu.edu/~blambi/xmljs/labels.html<http://millstone.iodp.tamu.edu/%7Eblambi/xmljs/labels.html>.
The interesting part is this:

function loadXmlData(xmlText)
{
    var parser = new DOMImplementation();
    var domDoc = parser.loadXML(xmlText);
    var root = domDoc.getDocumentElement();
    var ls = root.selectNodeSet('//label');
    var count = ls.getLength();
    var text = "<h5>There are " + count + " labels in this document with the
following names:</h5>";
    text += "<ul>";
    for (var i = 0; i < count; i++)
    {
        var nameNode = ls.item(i).selectNodeSet("name").item(0);
        text += "<li>" + nameNode.getFirstChild () + "</li>";
    }
    text += "</ul>";
    document.getElementById('info').innerHTML = text;
}


This just loads the xml text and then does a selectNodeSet to get the labels
and then another to get the name.  This is a much simpler approach than
messing around with types like that other example has you doing.  This
mostly follows the tutorial at
http://xmljs.sourceforge.net/website/contributedAddOns-xpath-documentation.html
