Want to know when an element is not in a node

[rosemm]

I am having another problem. I need to know when an element is not in a
node. Here is an example

.......
<NODE>
<Element1/>
<Element2/ value="SOMETHING">
</NODE>
<NODE>
<Element1/>
</NODE>
......

I would like to output "SOMETHING" for the first NODE shown and
"NOTHING" for the second node shown. Is there a way of knowing when an
element is not a child of a certain node?

element is not a child of a certain node?

For example in the template for NODE elements
<xsl:template match="NODE">
<xsl:choose>
<xsl:when test="Element2">
<xsl:value-of select="Element2/@value" />
</xsl:when>
<xsltherwise>
<xsl:text>NOTHING</xsl:text>
</xsltherwise>
</xsl:choose>
</xsl:template>

<xsl:if test="not(element2)"> .... no element2 child here ....
