Isn't that overly complicated, in general?
And is this actual code that outputs 1 product element as you stated? > <xsl:template match="level2"> > <xsl:if test="following-sibling::*[1][self::product[preceding-sibling::*[1][self::item] There is no following-sibling to level2. Maybe you intended to match level2/item and test some conditions about its following-siblings. Then your level2 template should copy level2 and apply-templates to ./item only. But this code still won't yield the quoted results. I'm trying to guess what you want to achieve from this inner code. > <xsl:variable name="count" > select="count(./following-sibling::product[position()!=last()])"/> > <xsl:if test="$count>= 1"> > <xsl:apply-templates > select="./following-sibling::product[position() < $count]"/> > </xsl:if> Is it: - $count is set to the number of products after item (not counting the last product though). In your case it should be 2. - If count is greater than or equal to 1, then the products whose position() is less than $count should be subject to apply-templates. In your example, this will be the first product. ? This may be achieved by this snippet: <xsl:template
match="level2/product[
preceding-sibling::item
and
(: All products before this one but after the
immediately precedent item must also be products:)
(
every $p in preceding-sibling::*[
. >> preceding-sibling::item[1]
] satisfies $p/self::product
)
and
(: All following siblings before level3 must also be
products. If there's no level3 then the every
expression evals to true() :)
(
every $f in following-sibling::*[
. << following-sibling::level3[1]
] satisfies $f/self::product
)
][
(: Restrict the result so far to all but the last
two items - don't know if this is really what you want:)
position() lt last() - 1
]
">
<!-- Really only apply, not copy? -->
<xsl:apply-templates />
</xsl:template><!-- Discard all other products: --> <xsl:template match="level2/product" priority="0"/> <!-- Everything else: identity -->
<xsl:template match="@* | *" priority="-1">
<xsl:copy>
<xsl:apply-templates select="@* | * | text()" mode="#current" />
</xsl:copy>
</xsl:template>But maybe you are looking for an xsl:for-each-group group-starting-with="item|level3", and then look at current-group()[1] whether it's item, and then process the rest of current-group() if it consists of products only? Gerrit
