XPath NodeSet in Java
提问by denniss
I have this code in eclipse
我在 eclipse 中有这个代码
NodeSet nodes = (NodeSet) xPath.evaluate(expression,inputSource, XPathConstants.NODESET);
and its giving me compile time error on NodeSet.
并且它给了我 NodeSet 上的编译时错误。
These are the stuff that I have imported. Can you tell me why it's doing this?
这些是我进口的东西。你能告诉我为什么这样做吗？
import javax.xml.xpath.*;
import org.xml.sax.InputSource;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.*;

As indicated NodeSet is not part of the standard libraries. However, from the documentation, NodeSet maps to a NodeList, so you could just use that instead. So it would become:
如上所述，NodeSet 不是标准库的一部分。但是，从文档中，NodeSet 映射到一个 NodeList，因此您可以改为使用它。所以它会变成：
NodeList nodes = (NodeList) xPath.evaluate(expression,inputSource, XPathConstants.NODESET);
You would have to import org.w3c.dom.NodeList.
您将不得不导入org.w3c.dom.NodeList.
