When you use xsl:number with an element as the current node, by default it counts all the elements that have the same name as the current element. You can tell the processor to only count certain elements by creating a pattern for those elements within the count attribute of xsl:number. If you want it to only count itemSet elements that have a non-empty itemDesc element child, then you can use the pattern: itemSet[normalize-space(itemDesc)] So you can number them with: <xsl:number level="multiple" format="1. " count="itemSet[normalize-space(itemDesc)]" /> By the way, I'm assuming that you do want to use level="multiple" and that itemSet elements that you're interested in at every level should have text within their itemDesc children.
