Hi

I have a transform going from XML to HTML, but I can't seem to get the
XslTransform class to output & as & even when using
disable-output-escaping.

I've tried writing the result to a Stream, but it still always converts the
values - it works fine if I use the MSXML library. Has anyone an idea how I
can get it to obey.

TIA

Paul

That's because
1) & should be escaped as & in HTML
(http://www.w3.org/TR/REC-html40/charset.html#h-5.3.2).
2) most likely you are using XslTransform in a way when
disable-output-escaping is ignored (e.g. transforming to XmlWriter or
even when creating attribute value).

Provided 1) I'd leave it alone.

I'm actually trying to output   into my HTML stream, but I can't use it
in the stylesheet as this raises an error so I use

<xsl:text disable-output-escaping="yes">&nbsp;</xsl:text>

I found out about the restrictions on using XmlWriter the hard way, and I'm
currently using a FileStream - but it I still get &nbsp; in the HTML

The XLST spec http://www.w3.org/TR/xslt#disable-output-escaping, seems to
say this is possible, but then the notes on XslTransform seem to imply that
the implementation is non-conformant.

You can just use   as a numeric reference to the nonbreakable
space. There is no need for any trickery here.

Sorry, I can't reproduce the problem, it works (and always worked) for
me. Show some repro - XML, XSLT, code where you run XslTransform.
