Optimize my code, Please

[Sgt-Peppa]

Hey, i am pretty new to C# and wrote some code for work. Before turnimg that in could you please take a alook and make suggestions to optimize it. I am pretty sure that there are ways to make this code a lot better. Thanx in advance,

Stephan

XmlDocument source = new XmlDocument(); //new Instance of xml-Document
source.Load(@"C:\cvs\TeccomPOC\xml\regExp.xml");  // select the xml source
XmlNode docElement = source.DocumentElement; // new Instance of Node

bool found =false; // Variable to keep track if a regexpresion has been found
bool goon = true; //Variable to break out of a foreach loop
int count =0; // keeping track of the amount of loops
int max = docElement.ChildNodes.Count; // count the childnodes

while (goon ==true && count<=max) // do as long as goon is true and the count has not reached the amount of childnodes 
{

	foreach(XmlNode n2 in docElement.ChildNodes)   //for every childnode in <doctypes>
	{
		if(n2.Name =="type") //if childnode is called type
		{
			foreach(XmlNode n3 in n2.ChildNodes) // for every childnode in <type>
			{	
				if (count ==max)
				{
				header = "UNKNOWN";
				}
				if (found == true) // has the regexpresion been found
				{
					header = n3.InnerText; // assign the name of the source to the header
					found = false; 
					goon=false;
					break;
				}

				if(n3.Name == "regexpression") // if childnode is called regexpression 
				{
					string tmp = n3.InnerText; // assign the tag-value to tmp
					if(rest.IndexOf(tmp) !=-1) //compare the tmp to the rest of the file
					{
						found =true; // if the regexp is found set found to true
					}
				}
			}
			count = count +1;		// keeping track of the amounts of loops
		}
	}
}

And heres my xml Structure:

<doctypes>

	<type>
		<regexpression>test::</regexpression>
		<name>test1</name>
		<containsbin>no</containsbin>
	</type>
	<type>
		<regexpression>testing::</regexpression>
		<name>test2</name>
		<containsbin>no</containsbin>
	</type>

</doctypes>
