Write: <xsl:variable name="href" select="@URL"/> or perhaps: <xsl:variable name="href" select="string(@URL)"/> It's shorter, it's more efficient, and it's more likely to give you the expected behaviour. For example xsl:if test="$href" in the first case will always return true, in the second case it tests whether the URL attribute exists, in the third case it tests whether the URL attribute exists and is non-empty. I've been seeing more and more of this construct, and it's a bad habit.
