在 XOM 中解析 XHTML 文档时出现 DTD 下载错误

我正在尝试使用声明使用的 doctype 来解析 HTML 文档过渡 dtd 如下：

http://www.w3.org/TR/xhtml1/DTD /xhtml1-transitional.dtd">

当我对文档执行 Builder.build 时，出现以下异常：

  java.io.IOException: Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
       at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1305)

       at nu.xom.Builder.build(Builder.java:1127)
       at nu.xom.Builder.build(Builder.java:1019)

如果删除 doc 类型声明，它解析得很好。我可以成功从我的浏览器下载 dtd，这告诉我网址有效。我不想删除文档类型声明。是有一种方法告诉构建者不要下载 dtd 或提供它有替代的 dtd 吗？

原文

I am trying to parse an HTML document with the doctype declared to use
the transitional dtd as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

When I do Builder.build on the document, I get the following exception:

  java.io.IOException: Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
       at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1305)

       at nu.xom.Builder.build(Builder.java:1019)

If I remove the doc type declaration, it parses just fine. I can
successfully download the dtd from my browser, which tells me that the
url is valid. I don't want to remove the doc type declaration. Is
there a way tell the builder not to download the dtd or provide it
with an alternate dtd?

这解决了这个问题：

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            factory.setValidating(false);
            factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
            Document document = factory.newDocumentBuilder().parse(is);

This solves the problem:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            factory.setValidating(false);
            factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
            Document document = factory.newDocumentBuilder().parse(is);
