Re: string replace with ­

I have an XML file that I am converting to HTML. In the processing, I have a string of the form
"machine.site.domain".  These strings can be fairly long.  When I output the HTML, I would to add a
hint to the browser that it can hyphenate this string at any ".".  So when I output the string I
would like it to be

machine­.site­.domain

So that it can be rendered as

machine-
.site.domain

David has answered your question, but can I ask why you want to do this
this way? It will be very misleading to your readers: the normal way to
break URLs over a line-end is to use a hyphenless break at punctuation
points only. My personal preference is to leave the punctuation at the
end of the line, but I know some editors prefer the punctuation at the
start of the next line, eg

machine.
site.domain

machine
.site.domain

But I urge you to use one of them and not introduce additional
characters which are not part of the name but could be misunderstood
by the unwary.
