Alistair introduced the Identity Transform: a template that copies everything, letting you override only what you need.

<xsl:template match="hcl:ShipmentOrder"> <xsl:for-each select="hcl:Packages/hcl:Package"> <xsl:value-of select="../../hcl:OrderID"/>, <xsl:value-of select="hcl:TrackingNumber"/>, <xsl:for-each select="hcl:Items/hcl:Item"> <xsl:value-of select="hcl:SKU"/>, <xsl:value-of select="hcl:Qty"/> <xsl:if test="not(position()=last())">|</xsl:if> </xsl:for-each> <xsl:text> </xsl:text> </xsl:for-each> </xsl:template> He was mixing a little imperative (the for-each ) with the declarative, and he didn't care.

It was perfect. Columns aligned. SKUs concatenated with pipes. Even the empty shipments were correctly represented as blank rows. Leo’s first challenge: transform a simple <Name> tag

By 6:00 PM Saturday, Leo had moved from "Beginner" to "Intermediate." He was now in the "Real-World Scenarios" section, which featured a 40-minute lecture titled: "The Horror of the Unnamed Namespace."

<xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> It looked like magic. A recursive mirror. Leo stared at it for ten minutes, tracing the logic. Then he had his Eureka moment. This is the power of XSLT. You don't iterate with for-each (Alistair called that "imperative blasphemy"). You let the templates find the nodes and decide their fate.
