I have a structure like this: This description is a bit imprecise ... do you need them paired, or will any <a1> before an <a2> suffice? I ask because in the example you have every <a2> has a preceding <a1>, some with intervening tags and some without. But it isn't true that every <a2> has a preceding <a1> that follows any preceding <a2>. I know that You shouldn't be working with name() because that deals with strings and not expanded node names in a namespace-safe fashion. The test that there is any <a1> before the current node being <a2> is: preceding-sibling::a1 The test that there is an <a1> correspondingly before every <a2> is approached more easily with XSLT 2 grouping from the parent of those siblings: <xsl:for-each-group select="*"
group-ending-with="a2">
<xsl:if test="not(current-group()/self::a1)">
Error! No corresponding a1 for the given a2
</xsl:if>
</xsl:for-each-group>I hope this helps. . . . . . . . . . . . .
