To add an xsl:if statement using drag and drop:

  1. In the Components window, select the XSLT Elements page.

  2. Expand the Flow Control section. You can click the plus sign (+) next to Flow Control to expand the section.

  3. Drag the if icon to the right side of the target node until you can see the green highlighting, as shown in Figure 41-13.

  4. Drop the if icon while the green highlighting is visible. An xsl:if node is added as the parent node of the target node.

  5. To set the condition for the xsl:if node, drag and drop the source node to the xsl:if node.

When viewed in source view, the xsl:if statement looks similar to the following: 

<xsl:if test="/ns0:PurchaseOrder/ns0:Comment">
    <tns1:Comment>
       <xsl:value-of select="/ns0:PurchaseOrder/ns0:Comment"/>
    </tns1:Comment>
</xsl:if>

The preceding xsl:if statement ensures that the target node is created only if the source node exists.
