Question

我有XML文件，如下所示

<?xml version="1.0" encoding="utf-8"?>
<Movies>
    <servername>
           raaja
    </servername>
    <moviename>
           xyz
    </moviename>
    <city>
           Hyd
    </city>
    <theatername>
           abc
    </theatername>
    <noofreels>
           16
     </noofreels>
     <aspectratio>
         216
     </aspectratio>
</Movies>

我想要标签servername和theatername的值。休息，我不想要。如何使用java获取这些。是否可以使用标记名获取值。

实现此目的的一种方法是使用JDK附带的DOM解析器。例如：

String url = getIntent().getStringExtra("webBrowserUrl");
webView.loadUrl(url);

使用StAX：

import org.w3c.dom.Document;
import org.xml.sax.InputSource;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import java.io.StringReader;

...

// Creates a new DOM parser instance.
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();

// Parses XML and creates a DOM document object.
// The XML variable is your XML document above stored as a string, but you could
// easily read the contents from a file or database too.
Document document = documentBuilder.parse(new InputSource(new StringReader(XML)));

// Get the text content of <theatername> using the DOM API and print it to stdout.
String theaterName = document.getElementsByTagName("theatername").item(0).getTextContent().trim();
System.out.println(theaterName);

如何从xml获取指定的根？
