Split a html string in N parts

阅读更多关于 Split a html string in N parts

问题 Does anybody have an example of spliting a html string (coming from a tiny mce editor) and splitting it into N parts using C#? I need to split the string evenly without splitting words.

XPath to first occurrence of element with text length >= 200 characters

阅读更多关于 XPath to first occurrence of element with text length >= 200 characters

How do I get the first element that has an inner text (plain text, discarding other children) of 200 or more characters in length? I'm trying to create an HTML parser like Embed.ly and I've set up a system of fallbacks where I first check for og:description , then I would search for this occurrence and only then for the description meta tag. This is because most sites that even include meta description describe their site in that tag, instead of the contents of the current page. Example: <html> <body> <div>some characters <p>200 characters <span>some more stuff</span></p> </div> </body> </html

Are there any settings on the HtmlDocument class that would assist in this, or do I have to find a way to execute the transformation before loading it with HtmlAgiliyPack? If yes for the latter, anybody know of a good library or method for such a transformation? Below is an example of a website that returns xml with xls file and the code that I would like to use. var uri = new Uri("http://www.skechers.com/"); var request = (HttpWebRequest)WebRequest.Create(url); var cookieContainer =
