Populate a dynamicaly built dropdown from a text file

Similar to the post, Populate a dropdown with text file and dynamically update the second drop down, I am looking to dynamically build a dropdown and have it populated with options from a .txt file. The .txt contains the html coded <options>, so I just need to be able to pull each line from the file and append it to the <select>.

Thank you,

The code example from Chapter 5 of Bulletproof Ajax shows how to retrieve HTML content from a file, and is the technique that I suggest that you use.
