XSLT output empty Debugging fails with no output - xslt

Question

I read through forums and i am unable to understand why the output is empty. It might be a simple thing i am missing.
I tried debugging in VS 2017 and it does not give any output any help in this matter is appreciated. IF i input only the ns0:EFACT_D96A_ORDERS_EAN008 node as an input to XSLT the output comes with the "test" content

Answer 1

A forward slash / at the start of the expression matches the document node, so doing select="/s0:EFACT_D96A_ORDERS_EAN008" will only select s0:EFACT_D96A_ORDERS_EAN008 if it is a child of the document node. i.e. if it is the root element, which it isn't.
To select s0:EFACT_D96A_ORDERS_EAN008 regardless of where it is in the document do this...
<xsl:apply-templates select="//s0:EFACT_D96A_ORDERS_EAN008" />
You also need to remove the single forward slash from the match expression too (You don't need the double-slashes in the match expression, as the match will work regardless of where the element is in the document)
Try this XSLT
