How to parse html based on class

Dealy

Hello,

I want to parse a webpage based on the class.Here's the div:

Value:

100.00

Special Request

What I want is to get the following text on the console:
Value: 100.00 Special Request.

I tried to use HtmlAgilityPack but i couldn't make it work.

Can you give me some help please?

Thank you in advance.

OK, but if you can't find a better way, then it's easy to use LINQ to XML to get the associated class names:

using System;
using System.IO;
using System.Linq;
using System.Xml.Linq;

class Test
{
static void Main()
{
string html = File.ReadAllText("dealy.html");
//html = "" + html.Substring(5, html.Length - 11) +"";
XElement root = XElement.Parse(html);
foreach(XElement xe in root.Elements())
{
string className = (string)xe.Attribute("class");
Console.WriteLine("{0} class = {1} -> {2}", xe.Name, className, xe.Value.Trim());
}
Console.ReadKey();
}
}

The output should be:

div class = valueCl -> Value:
div class = amount -> 100.00
span class = spReq -> Special Request

Incidentally, I thought previously that it wouldn't parse unless I changed the outer
...
to something else but in fact it parses fine so that step is unnecessary.

I think this might work, thank you!

Thanks for answering but i need a general solution. The above div was an example in order to see if anyone can help me get the inner text based on the class name.

I need to know that 100.00 came out of div class=amount and so on.

Thank you for trying though:)

Although it's not ideal, it's possible to parse a simple piece of HTML such as this by converting it to an XML document and then parsing it as a piece of XML.

Here's how you could do it in this particular case using LINQ to XML:

using System;
using System.IO;
using System.Linq;
using System.Xml.Linq;

class Test
{
static void Main()
{
string html = File.ReadAllText("dealy.html");
html = "" + html.Substring(5, html.Length - 11) +"";
XElement root = XElement.Parse(html);
string result = "";
foreach(XElement xe in root.Elements()) result += xe.Value.TrimEnd();
Console.WriteLine(result);
Console.ReadKey();
}
}

The output should be:

Value: 100.00 Special Request
