java - Xsl 找不到正确 XPath 的值

Question

我正在使用 saxon 9he、eclipse、tomcat 7。我将解释代码。当我运行转换时，我得到了我想要的所有值，除了 InsurerId。如果我（在调试中）将 xml 更改为 InsurerId2 和 xsl 以获取 InsurerId2 的值，它可以工作。我有两个字段给我带来了这个麻烦，我曾经能够在我添加更改为 xsl 2.0、从 saxon 6 更改、添加当前日期函数之间得到这个。这非常令人困惑，请帮助。

如果您想避免拥有 InsurerId，可以尝试以下操作。test.xml 包含您的 xml。

try {

            Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new File("D:\\Loic_Workspace\\Test2\\res\\test.xml"));

            XPath xpath = XPathFactory.newInstance().newXPath();
            NodeList ndList = (NodeList) xpath.evaluate("PersDriver/*[not(name()='ItemIdInfo')]", doc, XPathConstants.NODESET);


            for(int i=0;i<ndList.getLength();i++){
                System.out.println(ndList.item(i).getNodeName()+" "+ndList.item(i).getTextContent());
            }


        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SAXException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ParserConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XPathExpressionException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

这将在控制台中输出：

GeneralPartyInfo 


DALESANDRO
MAKIEH








SSN
666-18-6774



DriverInfo 

M
1979-08-23




2007-08-23
882827206
TN


PersDriverInfo

您可以通过执行以下操作来检查节点是否包含子节点，例如：

if(ndList.item(i).hasChildNodes()){
....
}

因此，您可以检查是否有必要以这种方式获取子节点值。这就是为什么我从控制台输出中获得所有空白空间的原因。

告诉我它是否有帮助；）

我正在用 saxon Impl 构建 parm xml... 删除它现在可以工作了？？？

前

DocumentBuilderFactory dfactory =
        DocumentBuilderFactory.newInstance("net.sf.saxon.dom.DocumentBuilderFactoryImpl",null); 
DocumentBuilder docBuilder = dfactory.newDocumentBuilder(); 
org.w3c.dom.Document document = docBuilder.parse(new InputSource(new StringReader(xmlSource)));
Transformer transformer = xsl.newTransformer();
transformer.setParameter("RsXml", document.getDocumentElement());

改回

DocumentBuilderFactory dfactory =DocumentBuilderFactory.newInstance();
