具体错误是Exception in thread "main" java.net.MalformedURLException: no protocol，因为将html输出到控制台，所以URL似乎是完全有效的-因此该错误可能并不有用。
呆在Saxon-HE和tagsoup上，我应该首先验证streamResult吗？
读取控制台输出几乎像将html包裹在xml中，然后从Document中制作一个streamResult就足够了。 / p>
崩溃：

值得注意的是，没有结束xml标签。
代码：
public void parseFromURL() throws SAXException, ParserConfigurationException, IOException, TransformerException {
StringWriter writer = new StringWriter();
StreamResult streamResult = new StreamResult(writer);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
XMLReader xmlReader = XMLReaderFactory.createXMLReader("org.ccil.cowan.tagsoup.Parser");
Source source = new SAXSource(xmlReader, new InputSource(url.toString()));
Transformer transformer = transformerFactory.newTransformer();
transformer.transform(source, streamResult);
String stringResult = writer.toString();
LOG.fine(stringResult);
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = documentBuilderFactory.newDocumentBuilder();
Document document;
document = builder.parse(stringResult);
}
从xml看build格式良好的stringResult文档。
