Provide a random UUID to XSLT with XProc p:uuid

David Maus, 19. Feb 2018

Create a step that acts as source of the UUID. The step provides an XML document with a single uuid-element at its primary output port result. The uuid has a single attribute value which contains the UUID as value.

<p:uuid version="4" match="@value" name="uuid-source">
  <p:input port="source">
    <p:inline>
      <uuid value=""/>
    </p:inline>
  </p:input>
</p:uuid>

Connect the step to the p:with-param inside the p:xslt step.

<p:xslt>
  …
  <p:with-param name="uuid" select="/uuid/@value">
    <p:pipe step="uuid-source" port="result"/>
  </p:with-param>
  …
</p:xslt>

Done.
