Example#

<Record element="product">

  <PlaceObject>
    <Textblock width="{ $wd }">
      <Paragraph>
        <Value select="$articlenumber"/>
      </Paragraph>
    </Textblock>
  </PlaceObject>

The following example shows a more complex scenario: you can collect complex elements in a variable.

<Record element="products">
  <SetVariable variable="articletext"/>
  <ProcessNode select="article"/>
  <PlaceObject>
    <Textblock>
      <Value select=" $articletext "/>
    </Textblock>
  </PlaceObject>
</Record>

<Record element="article">
  <SetVariable variable="articletext">
    <!-- the previous contents is added -->
    <Value select="$articletext"/>
    <Paragraph>
      <Value select=" @description "/>
    </Paragraph>
  </SetVariable>
</Record>
