Re: [xsl] mystery #2: testing document() without failure

[Robert Koberg <rob@xxxxxxxxxx>]

Hi,

So is it wrong to rely on something like (if processor independence is 
important):

<xsl:variable name="test" select="document('test.xml')/test"/>
<xsl:choose>
  <xsl:when test="boolean($test)">
     <xsl:apply-templates select="$test"/>
  </xsl:when>
  <xsl:otherwise>
     <!-- error display -->
  </xsl:otherwise>
</xsl:choose>

it works in saxon.

best,
-Rob
