Question

I have the following xml file:

<?xml version="1.0" encoding="UTF-8"?>
<users>
<user id="0" firstname="John"/>
</users>

Then I’m trying to parse it with java, but getchildnodes reports wrong number of child nodes.

Java code:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(this.file);
document.getDocumentElement().normalize();
Element root = document.getDocumentElement();
NodeList nodes = root.getChildNodes();
System.out.println(nodes.getLength());

Result: 3

Also I’m getting NPEs for accessing the nodes attributes, so I’m guessing something’s going horribly wrong.

Answer 1

There are three child nodes:

• a text node containing a line break
• an element node (tagged user)
• a text node containing a line break

So when processing the child nodes, check for element nodes.
