解析或提取html表的内容

Question

Can I parse the html tables by giving only column name ?

Like only those data should be extracted from the table which matches those column names I give.

Like for example I have table of column names like serial no., name, address, phone no,total Rs..

And I want to extract the information about only name, phone no and total Rs.. Then how can I do it?

Answer 1

看一下HTML Agility Pack它提供了一个LINQ api，用于搜索html内容。

Answer 2

Yes you can. You can use XPATH to scan your html document (google for screen scraping). Another technique is UI testing frameworks like Watin which let you use CSS selectors and more to find elements on a HTML page and get the contents.

Answer 3

您可以使用具有HtmlProcessor类和Tables属性的Data Extracting SDK ，该属性将HTML表作为DataTable对象处理。
