RE: problem with the position function -- addendum

[Douglas Conklin <do...@nightfire.com>]

The problem doesn't seem to be in the position function(), some
rearrangement of the XSL shows the index param is not being given the value
of the position() function.

Subject: problem with the position function


Hi all,

    I am having a problem with the position() function when processing with
Xalan-J 2.2.0.

    In one particular usage of position() against a series of nodes, the
position() function always returns 0. 
    when processing with Xalan-J 1.0.1 the same application of the position
function returns the appropriate number. 

    I looked in the Xalan-j 2.2.0 docs / release notes / bug list, as well
as searched this mailing list, and I haven't seen anything like this. 

    Is this a tightening of processor against the XSL spec, or is this a bug
in the processor?

    TIA.

	easy,
	douglas d



    Here are a small example stylesheet, input xml, Xalan 1.0.1 output, and
Xalan 2.2.0 output.

    Note that when I remove the -1 from <xsl:value-of
select="position()-1"/> so that it is <xsl:value-of select="position()"/>,
the numbers are all 0, so it isn't the addition that is failing.
