Solution 1

Use a regex:

-+Warnings-+[^-]+-+

Should do it.

Following the example, a simple approach would be searching for the 'Warnings' line and then include in your result string all the remaining part.
e.g.

C#

public static string mytrim(string ins)
{
  string[] line = ins.Split(new char[] { '\n' }); // obtain an array of lines
  int n;
  for (n=0; n<line.Length; ++n)
  {
     if (line[n].Contains("-Warnings-")) // search for the 'Warnings' line
       break;
  }
  StringBuilder sb = new StringBuilder();
  for (; n < line.Length; ++n) // use the remaining (possibly empty) part for building the result string
  {
     sb.Append(line[n]);
     sb.Append("\n");
  }
  return sb.ToString();
}
