Question
I must create a list of all the records on a certain web page. In a text file, I obtained the page source. I have to go through each element of this node:
HtmlNodeCollection resultContainer = doc.DocumentNode.SelectNodes("//div[@class='result-list divider-y-5']");
To be able to create my list of records, I must verify the type (div, span, etc.), "id," and "class" properties for each element. A compilation of all s or s is not what I'm after. That won't help since I have no idea what kind of element I will encounter when I loop through them. I have to examine each one. Because the children of the aforementioned node collection have all the information I need. Any recommendations?
Accepted Answer
foreach(HtmlNode node in resultContainer)
{
//check node type
switch(node.Name)
{
case "div":
{
break;
}
case "p":
{
}
///....etc
}
//get id
String id = node.Attributes["id"].Value;
//get class
String class = node.Attributes["class"].Value;
}

I believe that using the HtmlAgilityPack to convert an HTML page to an XML file is simpler.
doc.Load(htmlStream, true);
doc.OptionOutputAsXml = true;
doc.OptionFixNestedTags = true;
doc.OptionAutoCloseOnEnd = true;
doc.Save(/* your Xml stream or filename */);
then parse the data using the standard.NET xml api (using, for example, XmlDocument or XDocument).
