如何从html字符串获取DOM树? [英] How to get a DOM tree from a html string?
问题描述
我在字符串变量中包含网页的源代码(html代码).我只想获取这些html代码的DOM树.我使用了HtmlDocument类，它具有HtmlElement-s，但似乎不是树状结构.而且我不知道如何使用HtmlDocument.DomDocument(MSDN没有帮助).
我只需要使用.Net框架工作在c#中执行此操作:
//字符串SourceWeb =< html网页代码.>
1)从SourceWeb获取DOM树.
2)访问此DOM树的根.
3)访问Root(或其他节点)的子代.
我想手动遍历树，而不是通过Id或TagName或类似的方式获取元素.
谢谢.
Hi,
I have the source codes (html codes) of a web page in a string variable. I just want to get a DOM tree of those html codes. I used HtmlDocument class and it has HtmlElement-s but it seems it''s not tree structured. And I don''t know how to use HtmlDocument.DomDocument (MSDN didn''t help).
I just need to do this in c# using .Net frame work:
// string SourceWeb = <html codes of a web page.>
1) Getting a DOM tree from SourceWeb.
2) Access to the Root of this DOM tree.
3) Access to children of Root (or other nodes).
I want to traverse the tree manually, instead of getting elements by Id or TagName or something like that.
Thank you.
