test for blank

I'm trying to test for a value of nothing for with
XSL. I understand there are no 'else' statements
available in xsl so I'm trying to get this to work. I
thought using the not function would work but so far
the only output I'm getting is from the 1st nested if
statement

Here are my if statements:

<xsl:if test="@value">
						<xsl:if test="@value[contains(., '')]">
							There is nothing to see
							</xsl:if>
						<xsl:if test="@value[not(contains(., ''))]">
							<xsl:value-of select="."/>
							</xsl:if>										
						</xsl:if>
