如何从互联网加载XML文件到字符串

Question

目前我有一个Java应用程序，它将XML从本地文件加载到字符串中。我的代码看起来像这样

 private String xmlFile = "D:\\mylocalcomputer\\extract-2339393.xml"; 
    String fileStr = FileUtils.readFileToString(new File(xmlFile)); 

我怎样才能得到XML文件的内容，如果它位于在互联网上，在像http://mydomain.com/xml/extract-2000.xml网址？

Answer 1

尝试萨克斯接口

private String xmlURL = "http://mydomain.com/xml/extract-2000.xml"; 

XMLReader reader = XMLReaderFactory.createXMLReader(); 
reader.setContentHandler(handler); 
reader.parse(new InputSource(new URL(xmlURL).openStream()));

检查这个代码：

DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
    InputStream inputStream = new FileInputStream(new File("http://mydomain.com/xml/extract-2000.xml")); 
    org.w3c.dom.Document doc = documentBuilderFactory.newDocumentBuilder().parse(inputStream); 
    StringWriter stw = new StringWriter(); 
    Transformer serializer = TransformerFactory.newInstance().newTransformer(); 
    serializer.transform(new DOMSource(doc), new StreamResult(stw)); 
    stw.toString();
