This example takes text input and removes portions of the text based on a set of start and end parameters. This can be very useful for removing certain tags or comments in HTML or XML that have variable inputs in the middle. For Example: If your input HTML string is as follows:
<html>
<body>
<!-- Page Updated on 10/15/2010 -->
Test test test
</body>
</html>
The if you give the function an input parameter of "<!--" and "-->" it will remove the first tag that begins with <!-- and ends with -->, resulting in:
<html>
<body>
Test test test
</body>
</html>

NOTE: This will only remove the first instance of the tag. If you want to remove multiple of the same tag, you should enumerate them in the input "Parse Parameters" array.
