Java XPath: Get all the elements that match a query
java, namespaces, xml, xml-namespaces, xpath
Solution
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
Problem
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?
