Why does XmlDocument.LoadXml throw System.Net.WebException?

由 放肆的年华 提交于 2019-12-06 19:50:29
问题 Why does System.Xml.XmlDocument.LoadXml method throw System.Net.WebException ? This is really mind boggling crazy, if MSDN was right, LoadXml should at most give me a System.Xml.XmlException .

Dim document As New XmlDocument document.LoadXml("<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""><x></x>") MsgBox

Library to generate .NET XmlDocument from HTML tag soup

由 一世执手 提交于 2019-12-06 05:36:02
I'm looking for a .NET library that can generate a clean Xml tree, ideally System.Xml.XmlDocument, from invalid HTML code.

The library should also be well-maintained. :) I realize this is a lot (too much?) to ask, and I would appreciate any useful leads. There seem to be a fair number of implementations of this for Java, but I would rather not generate my own bindings. So far for .NET I have found http://www.majestic12.co.uk
