You need to explain in more detail exactly what you are trying to achieve: at the moment it looks like all you want to remove ar eteh lines which say "[item1]" and "[/item1]" but you need to expand on that even if that is true. Is the text that identifies the lines always "item1"? If not, how can you tell that "item2" should not be included? What should happen to the data between the two lines?

What have you tried?
Where are you stuck?
What help do you need?

The question might be more clear if you posted some examples of what you have tried and why it hasn't succeeded.

Are you trying to remove the empty lines? If so one way would be to use:

string[] lines = File.ReadAllLines("path");

using(var writer = File.AppendText("newpath"))
{		
  foreach(var line in lines)
  {
    if(!String.IsNullOrWhiteSpace(line))
    {
      writer.WriteLine(line);
    }
  } 
}
