我得到以下错误而设置的TransformerFactory的功能。
javax.xml.transform.TransformerConfigurationException: Cannot set the feature 'http://apache.org/xml/features/disallow-doctype-decl' on this TransformerFactory.
at org.apache.xalan.processor.TransformerFactoryImpl.setFeature(TransformerFactoryImpl.java:416)
代码段是::
public static TransformerFactory mytFactory;
mytFactory = TransformerFactory.newInstance();
mytFactory.setFeature(“http://apache.org/xml/features/disallow-doctype-decl“, true);
请帮我解决这个问题。
我也没有打电话TransformerFactoryImpl的方法“setFeature”。 而且我发现其他方式使用的XMLReader如下设置功能：
XMLReader reader = XMLReaderFactory.createXMLReader();
reader.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
Source xmlSource = new SAXSource(reader, new InputSource(new FileInputStream(xmlFile)));
Transformer transformer = TransformerFactory.newInstance().newTransformer();
StreamResult result = new StreamResult(new StringWriter());
transformer.transform(xmlSource, result);
该设置后，如果输入有内部DOCTYPE标签，我们将有以下情况除外：
javax.xml.transform.TransformerException: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 10; DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true.

希望这是对你有帮助。
