Re: [xsl] Entities in XSL (again)

Ken,
Thanks. I used the nbsp as a sample but was thinking also about non HTML
entities but this is great for those entities that are defined in HTML. I sort
of forgot about the html method which makes all if this very simple.

in if needed on the output.

Ouch!

That is not the use case for
disable-output-escaping="yes".

The entity "&nbsp;" is from an entity set used
by HTML.  The HTML serialization recognizes this and is supposed to use the
entity name when the result tree is serialized:
http://www.w3.org/TR/2007/REC-xslt-xquery-serialization-20070123/#HTML_CHARDA
TA
  Entity references and character references SHOULD be used only
  where
the character is not present in the selected encoding, or
  where the visual
representation of the character is unclear (as
  with &nbsp;, for example).
However you declare or use the entity in the XML file, if the result tree text
node has &#x160; and you are using HTML serialization, then you should get
what you want.

Now if you want to serialize your result tree as XML then you
may be stuck:  using disable-output-escaping="yes" for &nbsp; will produce a
non-well-formed result because there is no entity declaration.  Unless,
perhaps, you are using standard XSLT to add the DOCTYPE declaration pointing
to an external declaration subset that includes a declaration for that entity.
I hope this helps.
