Answer 1

In XPath 1.0 (XSLT 1.0):

not(parent::*)

Or you may use:

generate-id(..) = generate-id(/)

In XPath 2.0 (XSLT 2.0):

.. is root()

Answer 2

You can use not(ancestor::*).

Usage Example:

  <xsl:template match="node()|@*">
    <xsl:if test="not(ancestor::*)">
      <xsl:message>The root element is "<xsl:value-of select="name()"/>".</xsl:message>
    </xsl:if>
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
