我怎样才能在 html 字符串中找到额外的关闭 div

Question

I have some html stored in database . I dont know that html stored in databse has extra closing div like </div> or not. I want to find extra closing div in html string. I have tried to find using HTML Agility pack but not find the way to achieve this. Example:

<div class="readers">
    A total of 218 users are reading this article.
</div>
</div>
</div>

How can i find these two extra closing div and extract fully valid html.

Answer 1

Use this pure javascript parser before rendering the html: http://ejohn.org/blog/pure-javascript-html-parser/

You can check out by pasting your code here, http://ejohn.org/apps/htmlparser/ it removes the extra </div> s.

You just need to pass your html to the HTMLtoXML function as:

HTMLtoXML(your_html);

and it would remove the extra closing tags. Infact what it does is that it converts it into xml format, but since you are dealing with html strigs & all tags are expected to be valid in html, you can be safe to use this.

EDIT: You can easily call javascript functions from a C# file. See this question for more details.
