XSLT transform (XML to XML) with additional line feed

Hi All,

when using an XSLT transformation, webmethods adds an extra crlf after each source line. How can I avoid that?
I am trying to add a processing instruction.

Regards,
Michel

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="[URL]http://www.w3.org/1999/XSL/Transform[/URL]">
<xsl:output method="xml"/>

<xsl:template match="/">
<xsl:processing-instruction name="xml-stylesheet">href="Logistikzahlung.xsl" type="text/xsl"</xsl:processing-instruction>
   <xsl:copy-of select="*"/></xsl:template>
</xsl:stylesheet>

used pub.string:replace instead xslt now
