在Java中查询XML的最简单方法
问题描述：
我有一些带有XML的小字符串，例如：
I have small Strings with XML, like:
String myxml = "<resp><status>good</status><msg>hi</msg></resp>";
我想查询以获取他们的内容。
which I want to query to get their content.
最简单的方法是什么？
What would be the simplest way to do this?
答
XPath ，没有外部依赖关系：
XPath using Java 1.5 and above, without external dependencies:
String xml = "<resp><status>good</status><msg>hi</msg></resp>";
XPathFactory xpathFactory = XPathFactory.newInstance();
XPath xpath = xpathFactory.newXPath();
InputSource source = new InputSource(new StringReader(xml));
String status = xpath.evaluate("/resp/status", source);
System.out.println("satus=" + status);
