Re: [xsl] template matching with modes, not seeing what I expect

Well the good news is that the simple test example I just created for you
did copy the input document, although the subsects attributes were not all
correctly filled in. While I work on chasing down the programming error that
must be buried in there somewhere, I still have the problem of why my simple
example incorrectly sets the attribute.

Adding debug content has shown that my test message is correctly
constructing the temporary structure, so this problem lies in my tests for
the type of content.

Given this for $tempstruct:

  <title />
  <section />
  <section />

the attribute should be "all"

Given this:

  <title />
  <para />
  <table />
  <para />
  <img />

the attribute should be "none"

and given this:

  <section />
  <section />
  <para />
  <section />

the attribute should be "mixed"

The process I am using to try to get this result is ($tempstruct is passed
in as the parameter "top"):

<xsl:template name="testsections">
  <xsl:param name="top" />
  <xsl:for-each select="$top/*">
      <xsl:when test="not(section)"><xsl:text>none</xsl:text></xsl:when>
      <xsl:when test="not(not(section) and

This template correctly identifies the all and none options, but returns
"all" instead of "mixed" for the last example.

Tested on my full document (which has several hundred sections) I can see
that all the "all" sections and all the "none" sections are correct, and all
the "mixed" sections are erroneously reported as "all".

I thought the test "not(not(section) and not(title))" would be true for all
elements that had only title and section children. Evidently that's not

I tried the test "child::*[not(self::title)][not(self::section)]" as an
alternative, but that performed even worse.

I've missed some subtlety in evaluating presence and absence of specific
child elements, and it's probably in an FAQ somewhere, but if it is I missed

I'm testing a simple stylesheet which implements a suggestion made in 
reply to my previous approach, i.e. that I could process the output of 
a document into a variable to test. When the stylesheet is just 
reporting the results, it works just fine, but when I combine it with 
templates which copy the input document and replace one attribute 
based on those tests, the input document is not being copied.

But if I run this stylesheet and give it an input file (with no 
attributes) which contains a parent with multiple sections and mixed 
content, only the first section is output with the attribute 
(incorrectly set to "none"), and the rest of the output XML is the 
result of the mode="check" versions of the templates, i.e. the only 
output is the initial XML header followed by a copy of the $tempstruct 
variable built when the context node is the top level element of the 
input document.. The default templates simply aren't executed.

Can you show us a minimal sample input together with the output you get and
then one you want?
