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.
