This is a convenience function to add white space to the beginning of your XML. WhiteSpace is your padding, so insert the number of spaces, or tabs that you want to use. indentLevel is how many times to add your whiteSpace to the beginning of your XML. This is best used along with the XMLPrettyPrint custom function.
