Re: [xsl] test for blank

[Joerg Heinicke <joerg.heinicke@xxxxxx>]

contains() tests for substring. If you set the substring to test for to 
'', the test is also evaluated to true. Furthermore an "else" exists in 
XSLT, but not for <xsl:if>, but <xsl:choose> and <xsl:when>. You can use 
multiple (exclusive) <xsl:when>s and <xsl:otherwise>.

<xsl:choose>
  <xsl:when test="string(@value)">
    the value of @value is: <xsl:value-of select="@value"/>
  </xsl:when>
  <xsl:when test="not(@value)">
    <!-- no @value found -->
  </xsl:when>
  <xsl:when test="not(string(@value))">
    There is nothing to see
  </xsl:when>
</xsl:choose>
