使用C＃从HTML解析值

Question

I would like to be able to extract a number from the following mark-up:

<span class="hidden" itemprop="price">17.73</span>

This HTML has thousands of lines. This mark-up has the same format always. The price can change only.

I've tried parsing the HMTL using HtmlAgilityPack . I didn't succeed. Since the HTML format is always the same, there must be a better way to obtain the price value.

Can you give me suggestions about how to parse an HTML?

Answer 1

Use an XPath expression:

string x = document.SelectSingleNode(@"//span[@class='hidden' and @itemprop='price']").innerText;

where document is an HtmlElement/HtmlDocument.DocumentNode .

Answer 2

String x= webbrowser.Document.getelementsbytagname("span")[0].innerHtml
