Question

I’m using an XSLT to transform from one XML standard to another. The particular resulting XML standard contains a root element which is part of a namespace and a child node which is part of another namepsace.

The transform successfully reflects these namespaces but the child’s child now contains a blank xmlns attribute. How can I prevent this xmlns=""?

XSLT Snippet:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>

  <xsl:output method="xml" indent="yes"/>

  <xsl:template match="@* | node()">
    <xsl:apply-templates select="REQUEST_GROUP" />
  </xsl:template>

  <xsl:template match="REQUEST_GROUP">
    <ONCORE_ERECORD xmlns="http://test.com">
      <xsl:apply-templates select="REQUEST/PRIA_REQUEST/PACKAGE"/>
      <PAYMENT PaymentType="ACH" />
     <TRANSACTION_INFO _AgentKey="" _AgentPassword="" />
    </ONCORE_ERECORD>
 </xsl:template>

  <xsl:template match="PACKAGE">
    <DOCUMENT_RECORDATION xmlns="http://test2.org">
        <xsl:apply-templates select="PRIA_DOCUMENT"/>
    </DOCUMENT_RECORDATION>
  </xsl:template>

  <xsl:template match="PRIA_DOCUMENT">
    <PRIA_DOCUMENT _PRIAVersion="1.2">
      <xsl:attribute name="_Type">
        <xsl:value-of select="@RecordableDocumentType"/>
      </xsl:attribute>
      <xsl:attribute name="_Code"/>

  <xsl:apply-templates select="GRANTOR" />
  <xsl:apply-templates select="GRANTEE" />
  <xsl:choose>
    <xsl:when test="count(PROPERTY) = 0">
      <PROPERTY>
        <xsl:attribute name="_StreetAddress">
          <xsl:value-of select="@StreetAddress"/>
        </xsl:attribute>
        <xsl:attribute name="_StreetAddress2">
          <xsl:value-of select="@StreetAddress2"/>
        </xsl:attribute>
        <xsl:attribute name="_City">

  <xsl:apply-templates select="CONSIDERATION" />
  <xsl:apply-templates select="RECORDABLE_DOCUMENT/_ASSOCIATED_DOCUMENT" />
  <xsl:apply-templates select="EMBEDDED_FILE" />
</PRIA_DOCUMENT>

Source XML:

<REQUEST_GROUP PRIAVersionIdentifier="2.4">
  <REQUEST>
    <PRIA_REQUEST _Type="RecordDocuments">
      <PACKAGE>
        <PRIA_DOCUMENT PRIAVersionIdentifier="2.4" RecordableDocumentSequenceIdentifier="1" RecordableDocumentType="Mortgage">

Resulting XML:

<?xml version="1.0" encoding="utf-8"?>
<ONCORE_ERECORD xmlns="http://test.com">
  <DOCUMENT_RECORDATION xmlns="http://test2.org">
    <PRIA_DOCUMENT _PRIAVersion="1.2" _Type="Mortgage" _Code="" xmlns="">

I found a solution that worked, though it may not have been the most efficient way to achieve the desired results.

I simply changed all literal element declarations to:

</xsl:element>

and declared the namespace. The resulting xslt is as follows:

<xsl:template match="REQUEST_GROUP">
<xsl:element name="ONCORE_ERECORD" namespace="http://test.com">
  <xsl:apply-templates select="REQUEST/PRIA_REQUEST/PACKAGE"/>
  <xsl:element name="PAYMENT" namespace="http://test.com">
    <xsl:attribute name="PaymentType">
      <xsl:value-of select="'ACH'"/>
    </xsl:attribute>
  </xsl:element>
  <xsl:element name="TRANSACTION_INFO" namespace="http://test.com">
    <xsl:attribute name="_AgentKey">
      <xsl:value-of select="''"/>
    </xsl:attribute>
    <xsl:attribute name="_AgentPassword">
      <xsl:value-of select="''"/>
    </xsl:attribute>
  </xsl:element>
</xsl:element>
  </xsl:template>

  <xsl:template match="PACKAGE">
<xsl:element name="DOCUMENT_RECORDATION" namespace="http://test2.org">
  <xsl:apply-templates select="PRIA_DOCUMENT"/>
</xsl:element>
  </xsl:template>

  <xsl:template match="PRIA_DOCUMENT">
<xsl:element name="PRIA_DOCUMENT" namespace="http://test2.org">
  <xsl:attribute name="_PRIAVersion">
    <xsl:value-of select="'1.2'"/>
  </xsl:attribute>
  <xsl:attribute name="_Type">
    <xsl:value-of select="@RecordableDocumentType"/>
  </xsl:attribute>
  <xsl:attribute name="_Code"/>

  <xsl:apply-templates select="GRANTOR" />
  <xsl:apply-templates select="GRANTEE" />
  <xsl:choose>
    <xsl:when test="count(PROPERTY) = 0">
        <xsl:element name="PROPERTY" namespace="http://test2.org">
          <xsl:attribute name="_StreetAddress">
            <xsl:value-of select="@StreetAddress"/>
          </xsl:attribute>
          <xsl:attribute name="_StreetAddress2">
            <xsl:value-of select="@StreetAddress2"/>
          </xsl:attribute>
          <xsl:attribute name="_City">
