I am trying to learn how to write text parser. I have example doc 
with follow format:

#Header
my header text


my sub header text


my sub 3 text

#Header21
my header2 text


my header2 text


my header3 text



look like:

<div 1>
#Header
my header text
<div 2>

my sub header text


my sub 3 text
</div 3>
</div 2>
</div 1>

<div 1>#Header21
my header2 text


my header2 text


my header3 text
</div 3>
</div 2>
</div 1>

It's seems that I wrong understand parser logic. I am trying to 
do it's in next way:

	bool isH1Open;
	bool isH2Open;
	bool isH3Open;

	string newcontent;

	foreach(line; content.lineSplitter)
	{
		if(line.length > 3) // to prevent access to line < 3 symblos
		{

			{
				isH1Open = true;
				line = `<div 1>` ~ "\n" ~ line ;
				newcontent ~= line;
				continue;
			}



			{
				isH2Open = false;
				line = "\n" ~ `</div 2>` ~ "\n";
				newcontent ~= line;
				continue;
			}


			{
				isH1Open = false;
				line = "\n" ~ `</div 1>` ~ "\n";
				newcontent ~= line;
				continue;
			}

	

			{
				isH2Open = true;
				line = "\n" ~ `<div 2>` ~ "\n" ~ line ;
				newcontent ~= line;
				continue;
			}


		}

But I am getting wrong output:

<div 1>
#Header
<div 2>

</div 1>

</div 2>
<div 1>
#Header31
<div 2>


it's there any better way to parse such format?
