I understood that to produce well-formed xml in situations where start
and end tags are conditional, disable-output-escaping (or xsl:output
mode="html") were required. If I leave it off, the output will be
<tr> will it not?
Do not think in terms of tags when using XSLT.
XSLT does not produce a stream of tags but a tree.
You want to conditionally produce some branch of a tree so that is
<xsl:if...
<tr>
..
</tr>
</xsl:if>
grouping things into the correct <tr> groups is what is usually known as
the "grouping problem" for which there is lots of help in the FAQ or
Jeni's site. disable-output-escaping is not a recommended solution
to this problem and as I say will not work at all in many situations,
in particular it is almost guaranteed not to work in any situation where
the result is passed as an in-memeory tree to the next process (eg as
happens in mozilla or netscape or cocoon). In general it is a bad idea
to give disable-output-escaping as an answer to a user question unless
you are very sure the user is in a special situation where it is
unavoidable.
