Parsing XML in Java

[(MC3)RaVeN]

Hello Experts

I got a slight problem. I have been trying to read in XML in Java using the javax.xml.parsers.DocumentBuilder and javax.xml.parsers.SAXParser classes but to no success . I new to using XML with java.

What I need is to parse XML and be to retrieve the values or each tag.

Below is a sample of the XML i need to pass:

<?xml version="1.0" encoding="utf-8" ?>
<ns:SISubscriberProfile xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns="http://www.openuri.org/">
<ns:Type>1</ns:Type>
<ns:Message>GET_CUSTOMER : SUCCESS</ns:Message>
<ns:ErrorCode>0</ns:ErrorCode>
<ns:Value>
<ns:FirstName>Shaun</ns:FirstName>
</ns:Value>
<ns:IsLive xsi:type="xsd:boolean">true</ns:IsLive>
</ns:SISubscriberProfile>

If you take the line <ns:FirstName>Shaun</ns:FirstName>. I need to be able to pass a string (tag name, example "ns:FirstName") to a method and it should return the value of that tag as a string ("Shaun"). All the values i need to read are Strings.

I use the basic code in the attachment (rename file to *.java).

I can read the tagname but i can't get the value . What am i doing wrong? If possible could someone help me out by showing me the right code to read the value between the XML tag.

Thank you.

I am definitely no xml expert but this hack produced the name value

public String parseXML(Document doc, String tagname) {
    StringBuffer sb = new StringBuffer();
    NodeList nodes = doc.getElementsByTagName(tagname);
    sb.append(tagname).append("=");

    for (int i = 0; i < nodes.getLength(); i++) {

      Node node = nodes.item(i);

      NodeList nList = node.getChildNodes();

      for (int j = 0; j < nList.getLength(); j++) {
        Node n = nList.item(j);

        System.out.println("getNodeValue: " + n.getNodeValue());
        if (j > 0) sb.append(",");
        sb.append(n.getNodeValue());
      }
    }

    return sb.toString();
  }
