last() not same in Xalan1 or Xalan2

[Loïc Trégan <lt...@hotmail.com>]

Hi all,

Find under the XSL and XML used for sample.

result of last() is different under Xalan 1.2 and Xalan 2.0;xalan 1 returns
:
    rule END3;
    rule END3;
    rule END3;

but xalan 2 returns:
    rule END0;


performance issues : if I use count() with xalan 2, which solves my problem
but performance issues may happne. The XSL becomes ;

    <xsl:variable name="count">
        <xsl:value-of select="count("//transition[@to=$activityID]")" />
    </xsl:variable>
      <xsl:for-each select="//transition[@to=$activityID]">
        rule <xsl:value-of select="$activityID" />
        <xsl:value-of select="$count" />
      </xsl:for-each>

wich means that the complex file://transition[@to=$activityID] is processed
twice.
  - is true or is there a caching used internally ?
  - if true, how can I speed up the template ? maybe store match the
expression in a variable, convert the document fragement to a node list,
then reuse this node list in the select and in the count ?

thanks for your help.

Loïc --

Under the lastest build of XalanJ2, it returns

      rule END3

which is still wrong, however.  I'm looking into what the problem is and
I will let you know.  Thanks for reporting this problem.
