I've had a similar problem, I needed to test an image file exists and
if exists I needed width and height.

<xsl:template name="file-exists" xmlns:file="java.io.File">
  <xsl:param name="filename"/>
  <xsl:value-of select="file:exists(file:new($filename))"/>
</xsl:template>

<xsl:template name="image-size" xmlns:java="xalan://javax.swing.ImageIcon">
  <xsl:param name="mida" select="'width'"/>
  <xsl:param name="filename"/>

 <xsl:if test="normalize-space($filename)">
   <xsl:variable name="imatge" select="java:new($filename)"/>
    <!-- Extract image file info -->
    <xsl:choose>
    <xsl:when test="$mida='width'">
     <xsl:value-of select="java:getIconWidth($imatge)"/>
    </xsl:when>
    <xsl:when test="$mida='height'">
     <xsl:value-of select="java:getIconHeight($imatge)"/>
    </xsl:when>
    <xsl:when test="$mida='mida'">
     <xsl:value-of
select="java:getIconHeight($imatge)*java:getIconWidth($imatge)"/>
    </xsl:when>
    <xsl:otherwise>
     <xsl:value-of select="-1"/>
    </xsl:otherwise>
   </xsl:choose>
  </xsl:if>
</xsl:template>

I am having a similar problem in xslt 1.0 (MSXML).

We have a supplier ftp'ing some XML data but sometimes it doesnt
arrive and sometimes its invalid XML :(

Ive tried

<xsl:if test="msxsl:node-set(document('..\weather\weather.xml'))">
and
<xsl:if test="document('..\weather\weather.xml')">

but both throw errors and the template stops.

Is there any way I can test the validity of the document to be
imported and handle it gracefully?

Cheers
