Finding Node of Matching Raw Html in an HtmlAgility HtmlDocument

Question

Hi,

I currently have a program that finds and edits HTML files based on finding a tag with a matching id.

I would like to extend it to find a tag that has matching InnerHtml (disregarding capitalization and whitespace)

What is a good way to use Html Agility to do this? I would like to do it using Html Agility because the rest of the program is using it.

Thanks.

Rough shooting it here but you should be able to do something like this:

            HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("YOUR_TAG_SELECTOR");

            if (nodes != null)
            {
                foreach (HtmlNode node in nodes)
                {
                    if (node.InnerHtml.ToLower().Trim() == "YOUR_MATCH")
                    {
                        //success routine
                        break;
                    }
                }
            }

We've done this using Regular Expressions. Something like this works for us:

private static List<HtmlNode> GetMatchingNodes(string xPath, string pattern, HtmlDocument htmlDocument)
{
    List<HtmlNode> matchingNodes = new List<HtmlNode>();
    foreach (HtmlNode node in htmlDocument.DocumentNode.SelectNodes(xPath))
    {
     if (Regex.IsMatch(node.InnerHtml, pattern))
     {
      matchingNodes.Add(node);
     }
    }
    return matchingNodes;
}

Hope this helps. :)
