问题
I'd like to open an HTML document (as a string retrieved from a StreamReader, from the web), by creating a XMLDocument this way:
XmlDocument doc = new XmlDocument
doc.Load(string containing the retrieved document).
But since the HTML doc contains this head:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
It tells me that the document is invalid... Any way to workaround this?
回答1:
Normal html, even if it's valid html, is not valid xml.
There is a library called HtmlAgilityPack which is a popular 3rd party open source library that you can use to solve this problem:

回答2:
If you're positive that the HTML is valid XML, I imagine you could simply replace the HTML head with an XML one.
回答3:
first you have to validate that the XHTML is a valid XHTML document (it means that is a valid XML document too).
paste your XHTML code here and review the output. http://validator.w3.org/#validate_by_input
good luck!.

One can use HTML Tidy Tidy.NET for this.
