Get 4th node from nodelist - domparser java

Question

The value getting sent for execType is blank. The url Im using is fine, but the value being outputted for this is blank: System.out.println("Program title is: " + showTitleAttr);

protected static String getNodeAttr(String tagName, String attrName, NodeList nodes ) {
    for ( int x = 0; x < nodes.getLength(); x++ ) {
        Node node = nodes.item(x);
        if (node.getNodeName().equalsIgnoreCase(tagName)) {
            NodeList childNodes = node.getChildNodes();
            for (int y = 0; y < childNodes.getLength(); y++ ) {
                Node data = childNodes.item(y);
                if ( data.getNodeType() == Node.ATTRIBUTE_NODE ) {
                    if ( data.getNodeName().equalsIgnoreCase(attrName) )
                        return data.getNodeValue();
                }
            }
        }
    }

    return "";
}

 public static void main(String args[]) {
        try 
        {
            DOMParser parser = new DOMParser();
            String UrlToParse = "theurl";
            parser.parse(UrlToParse);
            Document doc = parser.getDocument();

            // Get the document's root XML node
            NodeList root = doc.getChildNodes();

            // Navigate down the hierarchy to get to the program node
            Node comp = getNode("ProgramGuideWCSResponse", root);
            Node exec = getNode("programGuide", comp.getChildNodes() );
            String execType = getNodeAttr("programTitle", exec);

            // Load the executive's data from the XML
            NodeList nodes = exec.getChildNodes();
            String showTitleAttr = getNodeValue("programTitle", nodes);

            System.out.println("Program title is: " + showTitleAttr);
        }
        catch ( Exception e )
        {
            e.printStackTrace();
        }
 }

the xml Im trying to parse, looks like:

ProgramGuideWCSResponse xmlns="urn:com:X:presentationflow:spps:services:programguide">
  <programGuide xmlns="">
    <startDate>2013-06-17-04:00</startDate>
    <endDate>2013-06-23-04:00</endDate>
    <locale>en_US</locale>
    <programs>
      <program>
        <programCode>XOA</programCode>
        <programTitle>The Oreck Challenge/Select Comfort Sleep Number</programTitle>

        </occurrences>
      </program>
    </programs>
  </programGuide>
</ProgramGuideWCSResponse>

Im basically trying to get the value of the 4th element "programTitle" from the root.

If anyone can help me, I am very new to Domparser. Thank you!

Since no one was able to help me, I figured this out on my own. I hope this helps others who may be trying to traverse an xml document:

 public static void main(String args[]) {
        try {
            DOMParser parser = new DOMParser();
            String UrlToParse = "puttheurl.com";
            parser.parse(UrlToParse);
            Document doc = parser.getDocument();

            // Get the document's root XML node
            NodeList ProgramGuideRoot = doc.getChildNodes();

            // Navigate down the hierarchy to get to the program node
                // Starting with Program Guide Root -> Program Guide -> All Programs -> Individual Program
            Node PGR = getNode("ProgramGuideWCSResponse", ProgramGuideRoot);
            Node PG = getNode("programGuide", PGR.getChildNodes() );
            Node Programs = getNode("programs", PG.getChildNodes() );
            Node IndivdualProgram = getNode("program", Programs.getChildNodes() );

            // Load the executive's data from the XML
            NodeList nodes = IndivdualProgram.getChildNodes();
            String showTitleAttr = getNodeValue("programTitle", nodes);

            System.out.println("Program title is: " + showTitleAttr);
        }
        catch ( Exception e ) {
            e.printStackTrace();
        }
 }
