In the following example, MPF calls the Write Request procedure for each organization and user in the data node. The ifNull="skip" attribute in the forEach node for name="user" instructs MPF to skip execution for the current iteration rather than fail the entire request whenever an organization does not have a user.

<request>
  <data>
	<organizations>
		<organization name="tailspintoys.com" type="primary" >
			<user name="joe"/>
			<user name="nancy"/>
		</organization>
		<organization name="wideworldimporters.com" type="primary">
			<user name="fred"/>
		</organization>
		<organization name="fourthcoffee.com" type="secondary">
		</organization>
		<organization name="adventure-works.com" type="secondary">
		</organization>
	</organizations>
  </data>
  <procedure>
	<execute namespace="Test Namespace" procedure="Write Request">
	<forEach name="organization" root="data" path="organizations/organization"/>
	<forEach name="user" root="organization" path="user" ifNull="skip"/>
	<before source="organization" destination="executeData">
		<xsl:template match="organization[@type='primary']">
		<primaryOrg>
			<xsl:value-of select="@name"/>
		 </primaryOrg>
		</xsl:template>
		<xsl:template match="organization[@type='secondary']">
		 <secondaryOrg>
			<xsl:value-of select="@name"/>
		</secondaryOrg>
		</xsl:template>
	</before>
	<after source="executeData" destination="data" destinationPath="orgSignup" mode="merge"/>
	</execute>
  </procedure>
</request>
