Parsing tables, cells with Html agility in C#

由 久未见 提交于 2019-12-03 22:32:56
问题 I need to parse Html code. More specifically, parse each cell of every rows in all tables. Each row represent a single object and each cell represent different properties. I want to parse these to be able to write an XML file with every data inside (without the useless HTML code). I have successfully been able to parse each column from the HTML file but now I don't know what my options are for writing this to an XML file. I am baffled. HTML: <tr><tr> <td class="statBox" style="border-width

HtmlAgilityPack DocumentNode.SelectNodes returns null, shouldn't

由 雨燕双飞 提交于 2019-12-03 18:12:27
问题 I'm trying to scrape content from an example page using the HTML agility pack. The DocumentNode.SelectNodes is returning null for an XPath query when I think it shouldn't.

How to clean up poorly formed HTML using HTML Agility Pack

由 你离开我真会死。 提交于 2019-12-03 14:14:27
I am attempting to replace this god awful collection of regular expressions that is currently used to clean up blocks of poorly formed HTML and stumbled upon the HTML Agility Pack for C#. It looks very powerful but yet, I couldn't find an example of how I want to use the pack which, in my mind, would be a desired functionality included in it. I am sure I am an idiot and cannot find a suitable method in the documentation. Let me explain... say I had the following html: <p class="someclass"> <font size="3"> <font face="Times New Roman"> this is some text <a href="somepage.html">Some link</a> <

HtmlAgilityPack selecting childNodes not as expected

由 谁说我不能喝 提交于 2019-12-03 10:29:45

In the following I have a HtmlNodeCollection of links. For each link I want to check if there is an image node and then parse its attribures but the SelectNodes and SelectSingleNode methods of linkNode seems to be searching the parent document not the childNodes of linkNode what gives? HtmlDocument htmldoc = new HtmlDocument(); htmldoc.LoadHtml
