Insert Text From A HTML file!

I want to create a text field where I can load external text written in a HTML file (not a TXT file with HTML content).

SInce I can create my text and format it in WINWORD for example, I want to create all the text there, save it as a web page, upload it to my server and then my index.swf file will load the text from this HTML file.
Is it possible? How can I do it?
Thank you so much.
