you should have been no outpout,mthis is a syntax error

<xsl:template match="@xmlns:xsi" />

xmlns:xsi is not an attribute so can't be accessed with @.
Just delete this template.

<xsl:template match="node()">
  <xsl:copy>


That copies the namespace that are in scope, which you don't want so
as described earlier:

<xsl:template match="node()">
  <xsl:element name="{name()}">



and add omit-result-prefixes="xsi" to your xsl:stylesheet
