seperating text content from style such as font sizes

[Jinpeng Xie]

Hi,

        I am reading JFC. I am pondering how to seperate text contents of
        one decument from its style such as font size, font, color when I
        save it. For example, I want to save text content into mytext.txt
        and its style into mytext.sty. When I reopen mytext.txt, program
        automatically search mytext.sty and render mytext.txt in terms of
        its style mytext.sty. Does anyone has ideal?
