Memory grows while transforming

           Summary: Memory grows while transforming
           Product: XalanC
           Version: 1.3.x
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: XalanC
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: floerke@doctronic.de


Take *big* XML-Document an apply with testXSLT the stylesheet appended.

If I use
        <xsl:with-param name="arg1">
          <xsl:value-of select="substring(.,2)"/>
        </xsl:with-param>
to pass the parameter the memory grows while transorming.

The whole Stylesheet for example:


  <xsl:output method="xml"/>

  <xsl:template match="*">
    <xsl:copy>
      <xsl:copy-of select="@*"/>

      <xsl:call-template name="foo">
        <!-- no memory grow
        <xsl:with-param name="arg1" select="substring(.,2)"/>
        -->
        <!-- memory grow -->
        <xsl:with-param name="arg1">
          <xsl:value-of select="substring(.,2)"/>
        </xsl:with-param>
      </xsl:call-template>

      <xsl:apply-templates/>
    </xsl:copy>
  </xsl:template>

  <xsl:template name="foo">
    <xsl:param name="arg1"/>
    <xsl:value-of select="$arg1"/>
  </xsl:template>

  <xsl:template match="text()">
    <xsl:copy/>
  </xsl:template>
</xsl:stylesheet>
