I think you've made it more difficult than it is.
name elements
that exist in every section (but do not contain the string
'new entry')
that's
distinct-values(/sections/section/name)
[not(contains(., 'new entry')]
[every $s in /sections/section satisfies $s/name = .])
So you assign this expression to a variable $ubiquitous-names and then do
<xsl:if test="exists($ubiquitous-names)">
<section name="allsections">
<xsl:for-each select="$ubiquitous-names">

Subject: [xsl] Wrapping a Condition around a literal result element
Hi
Given the following input, I need to remove name elements
that exist in every section (but do not contain the string
'new entry') and create a new section containing the aforementioned.
The stylesheet below gives me the desired result for this
given input, but the <section name="allsections"> element is
hard coded into the stylesheet. I will have instances where
no name elements exist in every section and therefore I do
not want to output a self closing section element. I am
struggling to write a condition around <section
name="allsections">. Any help would be appreciated.
Kind regards.
