Using a XPath query how do you find if a node (tag) exists at all?
For example if I needed to make sure a website page has the correct basic structure like /html/body and /html/head/title.

<xsl:if test="xpath-expression">...</xsl:if>
so for example
<xsl:if test="/html/body">body node exists</xsl:if>
<xsl:if test="not(/html/body)">body node missing</xsl:if>
