Remove XML namespace declaration from XSLT output root?

.net, xml, xml-namespaces, xslt

Solution

If you replace this template:

<!-- Copy content as is -->
<xsl:template match="node()|@*" name="identity">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*" />
    </xsl:copy>
</xsl:template>

With these two templates:

<!-- Copy elements without copying their namespace declarations -->
<xsl:template match="*" name="identity">
  <xsl:element name="{name()}">
    <xsl:apply-templates select="node()|@*" />
  </xsl:element>
</xsl:template>

<!-- Copy content as is -->
<xsl:template match="node()|@*" priority="-2">
  <xsl:copy>
    <xsl:apply-templates select="node()|@*" />
  </xsl:copy>
</xsl:template>

Then that should do it.

Problem

Having the following input XML: ``` <?xml version="1.0" encoding="utf-8" ?> <customSettings xmlns:env="urn:schemas-test-env"> <connectionStrings> <add name="Name" connectionString="None" providerName="" /> <add name="Name" connectionString="Local" providerName="" env:name="Local" /> <add name="Name" connectionString="Dev" providerName="" env:name="Dev" /> </connectionStrings> <appSettings> <add key="Name" value="Value" /> <add key="Name" value="Local" env:name="Local" /> <add key="Name" value="Dev" env:name="Dev" /> </appSettings> </customSettings> ``` and XSLT: ``` <?xml version="1.0" encoding="utf-8" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:code="urn:schemas-test-code" xmlns:env="urn:schemas-test-env" > <xsl:output version="1.0" encoding="utf-8" omit-xml-declaration="yes" indent="yes" /> <xsl:strip-space elements="*" /> <!-- Populate param value --> <xsl:param name="env" select="code:GetEnvironment()" /> <!-- Copy content as is --> <xsl:template match="node()|@*" name="identity"> <xsl:copy> <xsl:apply-templates select="node()|@*" /> </xsl:copy> </xsl:template> <!-- Remove all add nodes with env:name not matching param --> <xsl:template match="add"> <xsl:if test="not(@env:name != $env)"> <xsl:call-template name="identity" /> </xsl:if> </xsl:template> <!-- Remove all env:name attributes --> <xsl:template match="@env:name" /> </xsl:stylesheet> ``` I'm getting the following output XML: ``` <customSettings xmlns:env="urn:schemas-test-env"> <connectionStrings> <add name="Name" connectionString="None" providerName="" /> <add name="Name" connectionString="Local" providerName="" /> </connectionStrings> <appSettings> <add key="Name" value="Value" /> <add key="Name" value="Local" /> </appSettings> </customSettings> ``` How to remove namespace declaration from the root element?
