java Get value from xml tag

Question

I have an XML file:

<Header>
 <Id>A203</Id>
 <Name>ABC</Name>
</Header>

I'm trying to check whether the XML file's Id value is "A203" or not. I tried the following way but still can't get the value. I can't use xPath because I have an older Java version.

DocumentBuilderFactory dbfaFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = dbfaFactory.newDocumentBuilder();
Document doc = documentBuilder.parse(xmlfile);

doc.getElementsByTagName("Id").item(0).getNodeValue());   --tried this but cant

Answer 1

Getting the node value of an element will return null (as documented here ).

Instead you need to either get the element's text content (since Java 5):

doc.getElementsByTagName("Id").item(0).getTextContent();

Or, if you're stuck in Java 1.4 or older, you can access the element's text node and get the text node's value:

doc.getElementsByTagName("Id").item(0).getFirstChild().getNodeValue();
