我如何输出个人 <p> 使用HTML Agility Pack将标签添加到富文本框中？

Question

I'm just learning how to use HTML Agility Pack to scrape text off of webpages. I am looking to get the biographies of heros in Overwatch by Blizzard from their site. I'm currently using this to find and write the desired text to a rich text box.

var paragraphs = page.DocumentNode.SelectNodes("//div[@class='hero-bio-backstory pad-sm']");

     foreach(HtmlNode node in paragraphs)
     {
         rchTxtBox.AppendText(node.InnerText);
         rchTxtBox.AppendText("\n");
     }

What I am trying to get is the InnerText of each < p > with a return line in between them.

<div class="hero-bio-backstory pad-sm"> == $0
     <p>...</p>
     <p>...</p>
     <p>...</p>
     <p>...</p>
</div>

Instead of outputting each paragraph with a return character between them, it is writing all of them into one solid chunk. Is there a way to do this?

Answer 1

Your selector //div[@class='hero-bio-backstory pad-sm'] is returning one node - the entire div . When you then call InnerText on this node, it is returning the text in the entire div, sans markup. Therefore you are seeing the behavior you describe: your loop runs once, appends all the text in one chunk, then adds a single trailing newline.

You need to use an XPath expression which will select all the p nodes, ie //div[@class='hero-bio-backstory pad-sm']/p .
