我想就這個XML文件的XPath查詢的元素(可顯示摘錄):的Java的XPath:獲取所有匹配查詢
<?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>
...
我使用這個代碼片段:
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));
我很期待獲得:
MasterModel
MassimaleModel
TravelModel
什麼我越來越:
MasterModel
看來只有第一個元素被返回。我如何獲得與我的查詢匹配的所有匹配項?
你可以試試這個'// d:Component/d:Component.UsedModels/@ name'並不能確定它在java中的工作。它在Python中工作。 :) – Bob
