xpath给出一个空值的节点

Question

I am using XPath for the first time. While I am trying to get a node from xml I am getting a node with null value.

here is the xml file look like..

<?xml version="1.0" encoding="UTF-8"?>
<Message>
<Header>
<FromCompany>Content</FromCompany>
<From>Source</From>
<FromEmail>eg@eg.com</FromEmail>
<Toy>Pocket</Toy>
<SentDate>20300709</SentDate>
</Header>

...

I have written xpath expr as below ...

public XPath xPath =  XPathFactory.newInstance().newXPath();
Node message = (Node) xPath.evaluate("/Message", pxml, XPathConstants.NODE);
System.out.println("message::" + message);

When I execute message node is not null but is printing data as message::[Message: null]

I am not able to get the content of the node.. Could some one help me to find what I have done wrong?

Answer 1

In this context xPath will return a org.w3c.dom.Node , which is expected (I hope).

To get the contents of the node, you need to use Node#getTextContent , which, using your example, outputs...
