I am currently coding an XSLt to transform an XML
document to another XML with different formatting.

I cannot seem to know how to remove certain tags from
displaying when there is no value.  For example, if a
values exist for ListofDescription from the source
document, the output should display as:


(Element DescInfo can have 0 to n occurrences. These
are retrieved by xsl:for-each loop or apply-template
Element ListofDescription can have 0 or 1 occurence,
depending on the existence of DescInfo.)

However, if no value exists for DescInfo from the
source, then the <ListofDescription> tag should not
appear at all:


Is this possible? What syntax / logic should I use?

I would very much appreciate any help from you guys. 
Thank you.
