在 Java 应用程序中读取 XML 文件的最佳/最简单方法是什么?
问题描述：
目前我们的 Java 应用程序使用制表符分隔的 *.cfg 文件中保存的值.我们需要更改此应用程序，使其现在使用 XML 文件.
Currently our Java application uses the values held within a tab delimited *.cfg file. We need to change this application so that it now uses an XML file.
为了从该文件中读取值，最好/最简单的库是什么?
What is the best/simplest library to use in order to read in values from this file?
答
当然，根据您的需要，有很多好的解决方案.如果只是配置，你应该看看 Jakarta commons-configuration 和 commons-digester.
There are of course a lot of good solutions based on what you need. If it is just configuration, you should have a look at Jakarta commons-configuration and commons-digester.
您始终可以使用标准的 JDK 方法来获取文档:
You could always use the standard JDK method of getting a document :
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
[...]
File file = new File("some/path");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(file);
