select="address[normalize-space()]"

selects all address element children that have some non-whitespace 
text content within them.
select="address[not(normalize-space()]" selects address elements that 
contain only whitespace, nothing, or elements containing only 
whitespace, nothing (or elements containing only whitespace, nothing, 
etc). This is because it tests for the string value of the element, 
after whitespace is normalized and trimmed.
This can be changed or adjusted for other definitions of "content".
