hi i am trying to read a xml which have namespace defined and some tags are with namespaces. But namespace tags always give empty value when i use XPath to read those tags.
Sample XML
<?xml version="1.0" encoding="UTF-8"?>
<Employees xmlns:ULAD="http://www.datamodelextension.org/Schema/ULAD">
<EXTENSION>
<OTHER>
<ULAD:HMDAGenderType>Male</ULAD:HMDAGenderType>
</OTHER>
</EXTENSION>
</Employees>
Sample Java Program to read ULAD:HMDAGenderType
public static void main(String args[]) throws XPathExpressionException {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
try {
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse("C:\\test.xml");
XPathFactory xpathFactory = XPathFactory.newInstance();
XPath xpath = xpathFactory.newXPath();
XPathExpression expr = xpath.compile("/Employees/EXTENSION/OTHER/ULAD:HMDAGenderType");
System.out.println("Gender :: " + expr.evaluate(doc, XPathConstants.STRING));
} catch (ParserConfigurationException | SAXException | IOException e) {
e.printStackTrace();
}
}
Output:: null
Expected Output:: Male
How to read such tags?
Try using XPath local-name()
Instead of
XPathExpression expr = xpath.compile("/Employees/EXTENSION/OTHER/ULAD:HMDAGenderType");
Please try
XPathExpression expr = xpath.compile("//*[local-name()='HMDAGenderType']");
And to get the text attribute value directly you can use this XPath:
XPathExpression expr = xpath.compile("//*[local-name()='HMDAGenderType']/text()");
