在XOM中解析XHTML文档时出现DTD下载错误 [英] DTD download error while parsing XHTML document in XOM
问题描述
我正在尝试解析一个HTML文档，其中声明的doctype使用
过渡dtd，如下所示：
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 >
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
当我做Builder时。构建在文档上，我得到以下异常：
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

如果我删除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，它告诉我
url是有效的。我不想删除doc类型声明。
有没有办法告诉建筑商不要下载dtd或者用备用dtd提供
？
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?
推荐答案
快速查看 Builder ，我想你可以提供一个 EntityResolver 通过构造函数获取 XMLReader 。我会尽量避免让解析器从互联网上下载文件。
Taking a quick look at the javadoc for Builder, I guess you could provide an EntityResolver via the constructor that takes a XMLReader. I would avoid letting the parser download files from the internet where possible.
