Multiple lines on regex

Question

I have a html file from a website and I work with a regex to search for words and write these words to a document. I have this text:

<div class="scrollable " style="height: 200px;">
        <div>
            <p>CO-Schrank: nicht ben&ouml;tigtes ausbauen</p>
<p><strong>________________________________________________________________________</strong></p>

<p><strong>==&gt;&nbsp; wird nicht mehr ben&ouml;tigt!<br /></strong>z-B.: IUC</p>

<p>CO-Management in Gen. 2 implementieren</p>

<ol>
<li>Ausbau der PCI-Karten aus ZKA-PC in CO-PC- PC-Sys 02 TP 55, 56, 61 sind noch Profibus im ZKA-PC ==&gt; in CO-PC- PC-Sys 02 greift dann auf CO-PC f&uuml;r Datenaufzeichnung =&gt; Betrieb wieder aufnehmen</li>

<li>Ausbau der IUC</li>

<li>Testaufbau am CO-PC f&uuml;r den CO-Algorithmus und Datenspeicherung</li>

<li>Gen. 2 in CO-Management implementieren- pro Pr&uuml;fling 3 Min. (3 Min. x 48 HG x 10 Messungen)&nbsp;= 1440 Min. = 24 h- Messzeit 1-2 Min.</li>

</ol>


</div></div>

Now I want all the text in the <div>.... </div> too. I wrote this code but it is not working:

Match description = Regex.Match(line, "^<div class=\"scrollable \"^(.*?)$div>", 
    RegexOptions.Multiline);//multiple line

if (description.Success)
{
    //Console.WriteLine(status_id.Groups[1].Value);
    System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:\\Webasto\\csv-"+zahl+".txt");
    file.WriteLine(id.Groups[1].Value + ";4;4;" + subject.Groups[1].Value + ";" + due_date.Groups[1].Value+";NULL;"+status_id.Groups[1].Value+";"//+assigned.Groups[1].Value
        +";"
        +priority.Groups[1].Value+";NULL;"+autor.Groups[1].Value+";0;"+created_on.Groups[1].Value+";"+start_date.Groups[1].Value+";"+done_ratio.Groups[1].Value+";"+hours.Groups[1].Value
        +";NULL;"+id.Groups[1].Value+";1;2;0;"+closed.Groups[1].Value+";");
    file.Close();
}

You have a misunderstanding of what MultiLine means (I don't blame you, I have to think twice every time I use regex). MultiLine means that every line (ended with \n) is treated on its own.

You need SingleLine, which treats the whole string as if it was one line.

_{Side note: it is a bad idea to use Regex to parse HTML. Use a decent HTML parser instead.}
