RE: [xsl] Identity Transform losing original line feed

[Geert Josten <Geert.Josten@xxxxxxxxxxx>]

Ken,

Yes, XML readers normalize CR and LF. But I thought, writers would write CR
and LF based on OS again. At least, on my windows machine I see that most
processors are writing CR/LF..

Karl,

Tried using <xsl:output indent="no" /> together with <xsl:preserve-space
elements="*" />? As Jesper points out, it doesn't preserve *all* ignorable
white-space, but at least those between tags.

Kind regards,
Geert
