I want to make an XPath query on this XML file (excerpt shown):
<?xml version="1.0" encoding="UTF-8"?>
<!-- MetaDataAPI generated on: Friday, May 25, 2007 3:26:31 PM CEST -->
<Component xmlns="http://xml.sap.com/2002/10/metamodel/webdynpro" xmlns:IDX="urn:sap.com:WebDynpro.Component:2.0" mmRelease="6.30" mmVersion="2.0" mmTimestamp="1180099591892" name="MassimaleContr" package="com.bi.massimalecontr" masterLanguage="it">
...
<Component.UsedModels>
<Core.Reference package="com.test.test" name="MasterModel" type="Model"/>
<Core.Reference package="com.test.massimalecontr" name="MassimaleModel" type="Model"/>
<Core.Reference package="com.test.test" name="TravelModel" type="Model"/>
</Component.UsedModels>
...
I'm using this snippet of code:
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true);
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document document = builder.parse(new File("E:\\Test branch\\test.wdcomponent"));
XPathFactory factory = XPathFactory.newInstance();
XPath xpath = factory.newXPath();
xpath.setNamespaceContext(new NamespaceContext() {
...(omitted)
System.out.println(xpath.evaluate(
"//d:Component/d:Component.UsedModels/d:Core.Reference/@name",
document));
What I'm expecting to get:
MasterModel
MassimaleModel
TravelModel
What I'm getting:
MasterModel
It seems that only the first element is returned. How can I get all the occurrences that matches my query?
You'll get a item of type NodeList
XPathExpression expr = xpath.compile("//Core.Reference");
NodeList list= (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
for (int i = 0; i < list.getLength(); i++) {
Node node = list.item(i);
System.out.println(node.getTextContent());
// work with node
