[xsl] Checking null values in a string

Subject: [xsl] Checking null values in a string

Hey,
I wonder if there is some good useful function that checks if a for
example variable is empty and in that
case replaces it with an empty string. There is one good function in
PL/SQL that does this. The NVL function.
If there is no value just replace it with an empty string. Is there
anything similar in XSLT?
