Parse through xml string using JS

Question

I have an XML string in which Val.responseText gives me

<NewDataSet>
  <Table>
    <FieldID>21</FieldID>
    <TableName>F003v001</TableName>
    <FieldName>Grade</FieldName>
    <DisplayField>Grade</DisplayField>
    <FieldType>text</FieldType>
  </Table>
</NewDataSet>

I'm calling FillTable(sVal.responseXML.documentElement);

function FillTable(sResponse) {

    var preXML = sResponse;

    // code for IE
    if (window.ActiveXObject) {
        var doc = new ActiveXObject("Microsoft.XMLDOM");
        doc.async = "false";
        doc.loadXML(preXML);
    }
    // code for Mozilla, Firefox, Opera, etc.
    else {
        var parser = new DOMParser();
        var doc = parser.parseFromString(preXML, "text/xml");
    }

    // documentElement always represents the root node
    var x = doc.documentElement;

}

Now I want to parse through each of the node and populate a datagrid. Can anyone help me parse through the nodes?

How do i get the values for fieldid, tablename, displayfield?

I tried NodeList = doc.documentElement.selectNodes("Table") but nodelist.length gives me zero.

use the doc variable you created, instead of the documentElement, then you can use these methods on it.
