Bill: htmlagilitypack,c# Practical HTML Parsing class introduction

Htmlagilitypack is an HTML parsing class library under. Net. Supports parsing HTML with XPath. The meaning is not small, why? Because of the XPath of the elements on the page, some powerful browsers can be obtained directly, and do not need to be written manually. Saving most of the time to write regular expressions, while regular expressions sometimes need to be written for further acquisition, but after XPath parsing, the regular expression already has a very small range to match. Also, there is no need for regular expressions to match the entire page source code, and the speed will be improved. All in all, through the library, the browser gets to the XPath to get the content of the node and then the regular expression to match to the required content, whether it is development speed, or operational efficiency has been improved.
