checking for null

[Matthew Richardson <ma...@oceanlake.com>]

heres a simple one...hopefully... 

im just trying to check if there is <a href> inside an <a href> which i got
a hand with yesturday, but i cant seem to successfully check for null
..atleast i assume that it would get a null back if there wasn't a <a> tag
inside the other...   I just end up with no links on the screen at all. 

<xsl:variable name="testlink" select="a[@href and parent::a[@href]]"/>
<xsl:if test="$testlink=null">

... i also tryed
 <xsl:if test="ancestor::a">
... but that gave me the same result
