我尝试过使用以下Java代码：
XPath xPath = XPathFactory.newInstance().newXPath();
org.w3c.dom.NodeList titleNodes = (NodeList) xPath.evaluate("//Final-Results", xmlString, XPathConstants.NODESET);
我使用上面的代码得到以下异常：
javax.xml.transform.TransformerException: Unable to evaluate expression using this context
我在这里做错了吗？如果我的方法有误，你能否用一些伪代码分享你的想法以实现我的功能？
答案 0 :(得分：2)
您正在尝试执行以下操作：
NodeList list = (NodeList) XPathFactory.newInstance()
.newXPath()
.evaluate("/xml", "<xml />", XPathConstants.NODESET);
但是， String 是not a supported argument。实现期望Node。提供InputSource：
Reader xml = new StringReader("<xml />");
InputSource src = new InputSource(xml);
NodeList list = (NodeList) XPathFactory.newInstance()
.newXPath()
.evaluate("/xml", src, XPathConstants.NODESET);
假设XML是一个文件，提供二进制 InputStream 并让XML解析器检测字符编码。
答案 1 :(得分：1)
Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse("test.xml");
XPath xPath = XPathFactory.newInstance().newXPath();
org.w3c.dom.NodeList titleNodes = (NodeList) xPath.evaluate("//tempfolder", doc,XPathConstants.NODESET);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
StreamResult result = new StreamResult(new File("out.xml"));
for(int i=0;i<titleNodes.getLength();i++){
Node node = titleNodes.item(i);
DOMSource source = new DOMSource(node);
transformer.transform(source, result);
}

我尝试了几种方法。但是，以下代码对我有用：
import java.io.IOException;
import java.io.Reader;
import java.io.StringReader;
import java.util.List;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.xpath.XPathExpressionException;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import org.xml.sax.SAXException;
Reader xml = new StringReader("<xml />");
Document document = null;
SAXReader reader = new SAXReader();
document = reader.read(xml);
List <Element> elements = getXmlElements(document,"//Final-Results");
for(int index = 0; index < elements.size();index ++){
Element element = elements.get(index);
System.out.println("The required xml "+element.asXML())
}
getXmlElements（）方法在这里：
private List<Element> getXmlElements(Document document,String xPath) {
List<Element> elements = document.selectNodes(xPath);
return elements;
}
