> 'if defined' test on a variable? No, because either it is defined, or trying to reference it in a test would generate an error. your $onload variable must have some value always, perhaps in your `false' case it is the empty string, or null node list so you could do something like <xsl:if test=" ''= $onload"> <xsl:attribute name="onload">$onload</xsl:attribute> </xsl:if> or even, given the coersion of non empty strings to boolean true: <xsl:if test="$onload"> <xsl:attribute name="onload">$onload</xsl:attribute> </xsl:if> However it is possibly easier just to not bother with the test and just go <xsl:copy-of select="$onload"/> where onload has value either a null result tree fragment, or the result of running <xsl:attribute name="onload">something</xsl:attribute> David XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
