Re: [xsl] check if document exists

Hi,

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

My solution is with Java, I can't find another way to resolve it.

<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>
