Referencing text from a text file in an HTML file

I and my team create web based help for many applications. One problem we are finding is that the labels on the GUIs, among other things, are controlled by properties files, which the client can change. Thus, a label might change from [B]Date[/B], to [B]Start[/B] or [B]Begin[/B].

Thus, when the online help tells the user to enter a date in the [B]Date[/B] box, they can’t find the [B]Date[/B] box because it is now called the [B]Begin[/B] box (or whatever).

Is there a way, using HTML, Javascript, or some other means that I can use to put text in the HTML file containing the help topic by referencing a text file (or some other kind of file)?

I realize the answer to this could be a 200 page book or so, but I’d appreciate confirmation that it can be done and a pointer to the right direction to look.

Thanks!!
