Re: [xslt] Problem with variables

[Igor Zlatkovic <igor stud fh-frankfurt de>]

Hello,

strange, when I run it, I get

  C:\Home\Igor\tmp>xsltproc b.xsl a.xml

    %25
    %25.5
    %25.480
    %25.48
  C:\Home\Igor\tmp>

But, I am using the current CVS version, not the 2.4.21 release. Perhaps the
problem you are having is gone in the meantime.

I would ask a question: I am puzzled about the meaning of the '%' character
in the format string. My book says that per-cent and per-mille characters
are allowed, but does not say what they are for, neither it provides an
example. To make things more puzzling, MSXSL gives a different result:

  C:\Home\Igor\tmp>msxsl -u 4.0 a.xml b.xsl

    %
    %.3
    %.255
    %.2548
  C:\Home\Igor\tmp>

Now, can someone tell me what the per-cent and per-mille characters in the
format string mean? Which processor from the two above produced the correct
result?

Ciao
Igor
