RE: [xsl] #Please Help: Nested conditions

["Matthias Fischer" <it@xxxxxxxxxxxxxxxxxx>]

Thank you, Ken, also for your patient explanations to a newbie who
hasn't yet grasped fully the philosophy which is behind the XSL lexic
and grammar. I'll come to it later.

1st, your XSL snippet does not work out; the output is:
		<TABLE>
			<TTITLE/>
			<TBODY/>
		</TABLE>
I accept your gentle offer and attach the code of the input (an XML
export from a non-XML Adobe FrameMaker file) and the XSLT file to this
mail (see below).

2nd, let me come to your comments, the purpose of which, I guess, was to
make me understand once and for all. So let me try:

<Q>    <xsl:template match="TABLE">
<Q>      <TABLE>
<Q>          ...
<Q>         <xsl:if test="TROW/TH">
You are looking here for all <TH> that are children of a <TROW>;
however, if I know that all <TH> will always be in a <TROW>, I could
write also <xsl:if test="TH">, couldn't I? Or would this imply here that
I would be looking for <TH> that are children of <TABLE>?


<Q>             <xsl:apply-templates select="TROW[TH]"/>
A similar expression I have found in M. Kay's "XSLT P.R.2" at the item
"PredicateExpr". This is not where I would have looked for it, simply
because I've never heard the term "PredicateExpr"...


<Q>       <xsl:copy><xsl:apply-templates/></xsl:copy>
I would have written:
		<TROW><xsl:apply-templates/></TROW>
but I assume it would have been the same. Correct?


<Q> >                 <xsl:text disable-output-escaping="yes">
<Q> >                         &#60;&#47;TGROUP&#62;</xsl:text>
<Q> The above is expressly *not* the purpose of
<Q> disable-output-escaping= ...
I have used it as well to produce the DOCTYPE -- would that be ok?


<Q> A number of things that I have hopefully illustrated for you above.
Once again, thank you,

- Matthias
