Udemy Xslt !!better!! -

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."

He slapped his desk. he yelled. His cat, Loki, fell off the couch. Leo added a sticky note to his monitor: You are always somewhere. Know where. udemy xslt

<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 his solution. By 6:00 PM Saturday, Leo had moved from

<xsl:apply-templates select="ShipmentDetails/Package/Item"/> Nothing. The CSV was empty. He checked his XPath. It was perfect. He checked his spelling. Perfect. He replayed Alistair’s lecture. The answer was maddeningly simple: context . He was in the wrong context. The current node was still at the root. He needed ./ShipmentDetails... Leo added a sticky note to his monitor:

Sunday, 9:00 PM. Leo ran his transformation. Saxon-HE (the XSLT processor Alistair had recommended) hummed. The output file appeared: output.csv . He opened it.

Saturday morning, 8:00 AM. Coffee in hand, Leo opened Udemy and stared into the abyss. "The Complete XSLT Course: From Zero to Hero" by a British instructor named Alistair Finch. 4.6 stars. 14,000 students. 18.5 hours of video. Leo's eye twitched. He’d been burned before by "complete" courses that spent three hours on "What is a variable?"

<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.
