I am in the process of transforming an XML file, using a map based on a subtype in the header.

To make this logic happen I've used an xsl:if inside a template that matches on the root node. 

<xsl:template match="/">
  <xsl:variable name="var:invoiceSubtype" select="//Header/InvoiceType/text()"></xsl:variable>
  <xsl:if test="$var:invoiceSubtype = 'Invoice'">

Inside the xsl:if I've pasted the XSLT code for the map, without changing the xpath, but some of my elements are not showing any data, like this one:

<BELNR>
   <xsl:value-of select="/Header/InvoiceNumber/text()" />
</BELNR>

The structure of my schema up until the InvoiceType looks like this:

enter image description here

Using the double slash to select the element works, but I'd rather avoid using that, since there might be duplicate named elements.

Is there a way of showing where you currently are in the source schema when selecting nodes? I'm unsure as to what the correct path is.

You can just change to the full XPATH starting from the root to avoid using //Header/InvoiceType/text(), use: /CDM_PurchaseInvoice/Header/InvoiceType/text() instead.

Also if you are using namespaces you should take it into account in your xpath or by using the syntax /x:List/x:Fields/x:Fiels or /*[name()='List']/*[name()='Fields']/*[name()='Field'] otherwise you might end up extracting nothing even if the xpath looks correct at first glance.
