[XSL XHTML]   entity problem

[Tjerk Wolterink]

In XHTML the entity nbsp stands for  

A normal space like " " is also displayed as an normal space,
but multiple spaces like " " are interpreted as 1 space in the
xhtml page.
So there comes the   in handy: with "  " you have two
spaces. So with the nbsp entity you can create multiple spaces (in the display).

Now i have an xml file with   entities,
i put it in an xsl-file that know xhtml entities.
But the output of this:

"  "

is translated (correctly) to:

" "

But now the whole point of the   entity in xhtml is gone!!
How do you solve this problem

"&nbsp;&nbsp;"

" "

So those blank spaces between the quotes should be perfectly good
non-breaking-space characters, not ordinary spaces, and should work
just like &nbsp; references in XHTML.

so you mean that " " and " " can be different characters?

Yes, Unicode has several different characters that may look like that.

i have foudn a smart solution:

<!DOCTYPE stylesheet [
<!ENTITY nbsp
"<xsl:text disable-output-escaping='yes'>&amp;nbsp;</xsl:text>">
]>

now it works

Use it if your circumstances allow it and require it but be aware that
disable-output-escaping is an optional feature that is not supported by
every XSLT processor respectively output mode, for instance when the
result of the transformation is a tree that is not serialized then it
usually doesn't work.

i know what you mean, maybe the output document is valid and the " " is really a
non breaking space. the fact is that browsers like IE do not treat it like that.

But anyways, thanks for your help

How would validity be relevant here? (I suspect you are using the word
"valid" in some non-XML and not-so-well defined meaning.)
and the " " is really a non breaking space.
No, what you have typed here is surely a normal space. You could not
have included a no-break space (that's the term, btw) into your
posting, since your message headers specify 7bit transfer.

I wonder why you use &nbsp; in the first place. Why don't you simply
write no-break spaces in whatever encoding you are using? If your
authoring tool does not let you type them easily, maybe you need a
better tool, or to find out how to define keyboard macros in the tool
you are using, or something. Even in Notepad you can type no-break
spaces. (Typing Alt 0160 is not very convenient, but it's comparable to
typing the six characters &nbsp;.)
the fact is that browsers like IE
do not treat it like that.

The fact is that browsers, even IE, treat the no-break space exactly as
the &nbsp; or   reference when processing an HTML document. You
have done something wrong. In the absence of specific information, such
as a URL of a demo page, it is impossible to say what went wrong.

If you want to try to track down the problem, you could try setting
the output encoding of your stylesheet to ascii (using the encoding
attribute of the xsl:output element). The processor will then have to
use a character reference to output any non-breaking spaces (since
they aren't in the ascii character set), so you will be able to see
them more easily.

yes you are right, i just meant that the " " really is a non-breaking space,

ok maybe that is the case, i think i had some problem in the output-encoding,
but anyways i solved the problem with something completely different.

Use of disable-output-escaping almost always implies some kind of design
error in the stylesheet. It is also explictly non-portable and an
optional feature that may be ignored by the XSLT engine.
For example it will always be ignored in mozilla family browsers and
it will be ignored (for the same reason) in MSXML if outputting to a DOM
rather than to a character string.

You should just use & # 1 6 0 ; directly in the stylesheet.

Yes, it's mean to be. That's what parsing does, among other things:
it replaces entity references with the referents.
How do you solve this problem

Declare <!ENTITY nbsp "&#160;"> in your DTD or internal subset.
Now your &nbsp;s will be output as &nbsp;s
