so...
<xsl:for-each select = //embededMalware/malwareFamily">
<xsl:if test
="document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily[(_at_)id
= current()/@id]">
...
</xsl:if>
<xsl:value-of select = "@id"/>
</xsl:for-each>
I would think that current()/@id in the predictate holds the same value as
<xsl:value-of select = "@id"/>. Is that correct?

<xsl:for-each select = //embededMalware/malwareFamily">
<xsl:if test
="document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily[(_at_)id
= current()/@id]">
<xsl:call-template name="displayPrevalenceReport">
<xsl:with-param name="malwareFamilyId" select="@id"/>
<xsl:with-param name="items" select="5"/>
<xsl:with-param name="method" select="'lite'"/>
</xsl:call-template>
</xsl:if>
</xsl:for-each>
the problem seems to lay within my use of current()/@id in the predictate
and/or @id as the malwareFamilyId parameter.
If instead, I store the @id attribute in a variable, and then use that
variable throuought the for-each loop it all works ok. Why is this? Surely
the context hasn't changed along the way has it? Looking at that, to me it
looks as if
document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily is
the current contxt throughought the for-each loop,
No the current node for each iteration of the for-each is a
malwareFamily element from the current document.
document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily
is the current node only within the [] at the end of your test
expression.
so where you have
[(_at_)id = current()/@id]
@id referes to the id of an element in malwareFamilies.xml and
current()/@id refers to the id element of the malwareFamily element in
the current document that you are for-eaching over.
It is equivalent to
<xsl:for-each select = //embededMalware/malwareFamily">
<xsl:varaiable name="thisid" select="@id"/>
<xsl:if test
="document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily[(_at_)id
= $thisid]">
You said that you used a variable to make things work but you didn't say
where.
