Retrieving inner text using HTML Agility Pack

I need assistance with parsing a website I have found here:

https://i.sstatic.net/GdFN1.png

My goal is to extract information from specific fields that have IDs and classnames:

        label =
            node.SelectSingleNode(
                ".//h3[@class='item_header']"
                ).InnerText.Replace("Label: ","").Trim();
        Console.WriteLine(label);

However, I am struggling to retrieve the text contained in tags without any IDs or classes, like in the example below:

https://i.sstatic.net/74Wxf.png

How can I extract the text inside tags that lack identifiers, such as the following?

<b>Label Cat. #: WEST 3007/8</b>

If it helps, here is the unique selector for reference:

#\31 42248 > tbody:nth-child(1) > tr:nth-child(1) > td:nth-child(1) > b:nth-child(1)

Answer №1

Did you know that the HTML Agility Pack offers a CSS Selector library that can help you locate specific elements? This library can be a handy tool for web scraping projects.

To explore the CSS Selector library, you can visit the following link: https://www.nuget.org/packages/HtmlAgilityPack.CssSelectors/

Answer №2

If you already have the table's ID, you're good to go.

HtmlNodeCollection elements = doc.DocumentNode.SelectNodes("//table[@id='142248']//b");

foreach (HtmlNode element in elements)
{
    if (element.InnerText.ToLower().Contains("label"))
    {
         Console.WriteLine(element.InnerText);
    }
}

The xpath used in the code above will return all the elements within the table that has the ID 142248.
