我想跳过 DTD 验证，因为我没有互联网连接。是否可以在 java 中实现它。
我的代码是:
file = new File(filepath);
// Create instance of DocumentBuilderFactory
factory = DocumentBuilderFactory.newInstance();
// Get the DocumentBuilder
docBuilder = factory.newDocumentBuilder();
// Using existing XML Document
doc = docBuilder.parse(file);
我的错误是这样的，我知道这个错误的原因。

最佳答案
一个令人发指的黑客就是编写一个自定义 java.io.InputStream扩展，它只是在解析器看到它之前删除 DTD 引用。
