 preceding-sibling::node()[1]

> - how can I filter comments from it

<xsl:if test="preceding-sibling::node()[1][self::comment()]">
  ....
</xsl:if>

Don't forget though that most likely the immediate preceding element
will be some presentational whitespace, so you will need to strip that
out using:

<xsl:strip-space elements="*"/>

or a more specific selection in place of * (unless of course, you are
using msxml which strips it all out regardless).
