RE: [xsl] Simple Question

["Punnoose, Roshan" <punnooser@xxxxxxxxxxxxxxx>]

Thanks for the replies. I'm better understanding how XSLT works and with
a little help able to get this to work:

<xsl:if test="$a != $times">
 		<xsl:text
disable-output-espacing="yes">&lt;xqx:orOp&gt;</xsl:text>
 			...
 	</xsl:if>

Of course, there are problems in this too, but I'm working them out.

The reason I had to do it this way is because I'm working on a recursive
loop that prints out a binary node tree, which I sort of needed this
for. (Though there probably is a way to do it a little cleaner.)

Thanks!

It's actually a pretty deep question, though a very common one among
beginners.

XSLT doesn't "print out XML". It creates nodes in a result tree. The
result
tree is subsequently (and optionally) passed to a serializer, which
"prints
out" an XML representation of the tree. The problem isn't so much that
your
code is invalid XML, as that it shows a misunderstanding of the XSLT
processing model.

When you see in a stylesheet

<a>....</a>

that isn't an instruction to output a start tag, then do something
(....),
then output an end tag. It's a single indivisible instruction to output
an
element node named a, whose children are determined by the value of the
expression (....). Later on, if you choose to serialize the result tree,
the
serializer looks at the element node and serializes it using a start tag
and
an end tag.

As we've often remarked on this list, you can't create half a node.
