I'm using Regex to find some things in one websites source and then add all the things found in textbox in certain format (layout).

I know how to do regex etc. and everything works fine for me, but im stuck now when one of the things i need to find are not in the same line, they are structured one per line.

example of how it is in in the website source:

 
<li class="test"><div style="background-color:blue">Hello</div></li>  
<li class="test"><div style="background-color:blue">Hello1</div></li>  
<li class="test"><div style="background-color:blue">Hello2</div></li> 

basically i need only those "Hello", "Hello1" etc., so i have this regex which finds this pattern:

"<li class='test'><div style='background-color:blue'>(.+?)</div></li>"

And it works fine, it finds those "Hello" etc. which i want to find, but the problem is that i need ALL of them to be collected and put in one line seperated by commas in certain structure

To put the results in a multiline textbox, i use something like:

textBox1.Text = Environment.NewLine + textBox1.Text + Environment.NewLine +  "[start]" + Environment.NewLine + "string is: " + m.Group[1].ToString() + Environment.NewLine + "[end];

which prints out in layout like this:

 
[start]
string is Hello
[end]

But the problem is, that I want it to put that "Hello", "Hello1" and "Hello2" in same line seperated by commas like this:

 
[start]
string is Hello, Hello1, Hello2
[end]

What ever I try I just can't get it to work, the way it does it for me is like this...:

 
[start]
string is Hello
[end]
 
[start]
string is Hello1
[end]
 
[start]
string is Hello2
[end]

I know it's easy to do in php using "foreach" but it doesnt work for me on C# :S

Can someone pelase help me out here?

thanks.

try this might work:

textBox1.Text +=   Environment.NewLine +  "[start]" + Environment.NewLine + "string is: " + m.Group[1].ToString() + ",[end]";

Nah doesn't work. It's the same as the way I was doing it. :(

Here's an example program that I quickly done to make it easier for you to understand what I meant with all that stuff above:

}
}

And this outputs:

[Start]
The string is: Hello
[End]
[Start]
The string is: Hello1
[End]
[Start]
The string is: Hello2
[End]

But what I want it to output is:

[Start]
The string is: Hello, Hello1, Hello2
[End]

Thanks
