1. ./x is a long-winded way of writing x
2. You meant name()='subcategory' with quotes
3. ./*[name()='subcategory'] is a long-winded way of writing
./subcategory
4. The guy wants to know if the subcategory element exists, not if it
has non-empty text content.
5. Why test the same condition twice, rather than using xsl:choose?

Try instead:

<xsl:choose>
<xsl:when test="subcategory">Success</xsl:when>
<xsl:otherwise>Failure</xsl:when>
</xsl:choose>
