Please help me on this requirment.
Thanks.
i used below code but it is removing all the nso prefix's along with namespace declarations but i want to remove only nso prefix's for individual xml tags from the element "ns0:CstmrCdtTrfInitn" before this element i want to remove "ns0:" & ":ns0" and keep the declaration with out "ns0".

<xsl:template match="#*">
<xsl:attribute name="{local-name()}">
<xsl:value-of select="." />
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>

Answer 1

Change
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="#*|node()" />
</xsl:element>
</xsl:template>
to
<xsl:template match="/*//*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="#*|node()" />
</xsl:element>
</xsl:template>
and add a template
<xsl:template match="/*">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>

--- edited in view of changed requirement ---
To remove the ns0 prefix from all elements in the input XML, while keeping them in the original namespace, do:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="*">
<xsl:element name="{local-name()}" namespace="{namespace-uri()}">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
