We are in 11.5.10.2  so we are using XML 5.6.  How to add a carriage return when the variable has data in it.  below is my example.

My template is required to show customer addresses.  customer addresses can be long or short.  In 11.5.10.2, address is being split into multi-columns

Here are few sample of my the XML output file
<customer>ABC</customer>
<address1>123 Main street</address1>
<address2>RM 120</address2>
<address3> </address3>
<city>Seattle</city>

<customer>XYZ</customer>
<address1>1 fourth street</address1>
<address2></address2>                         -- address1, address2, address3 can be NULL
<address3></address3>
<city>New York</city>
