XSLT blank xmlns="" after transform
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=""
?

Source XML:
<REQUEST_GROUP PRIAVersionIdentifier="2.4">
<开发者_如何学Go;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="">
This is happening because PRIA_DOCUMENT is in the default namespace, while its parent DOCUMENT_RECORDATION is in a non-default namespace. You must put the PRIA_DOCUMENT in the same namespace as its parent, otherwise the serializer is required to generate xmlns=""
.
.
.
<xsl:template match="PRIA_DOCUMENT">
<PRIA_DOCUMENT _PRIAVersion="1.2" xmlns="http://pria.org">
.
.
.
See Michael Kay's "XSLT 2.0 and XPATH 2.0, 4th edition", page 475 where he discusses this exact situation.
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">
<xsl:value-of select="@City"/>
</xsl:attribute>
<xsl:attribute name="_State">
<xsl:value-of select="@State"/>
</xsl:attribute>
<xsl:attribute name="_PostalCode">
<xsl:value-of select="@PostalCode"/>
</xsl:attribute>
<xsl:attribute name="_County">
<xsl:value-of select="@County"/>
</xsl:attribute>
<xsl:apply-templates select="LEGAL_DESCRIPTION"/>
</xsl:element>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="PROPERTY" />
</xsl:otherwise>
</xsl:choose>
<xsl:choose>
<xsl:when test="count(PARTIES) = 0">
<xsl:element name="PARTIES" namespace="http://test2.org">
<xsl:element name="_RETURN_TO_PARTY" namespace="http://test2.org">
<xsl:attribute name="_UnparseName">
<xsl:value-of select="''"/>
</xsl:attribute>
<xsl:attribute name="_StreetAddress">
<xsl:value-of select="''"/>
</xsl:attribute>
<xsl:attribute name="_StreetAddress2">
<xsl:value-of select="''"/>
</xsl:attribute>
<xsl:attribute name="_City">
<xsl:value-of select="''"/>
</xsl:attribute>
<xsl:attribute name="_State">
<xsl:value-of select="''"/>
</xsl:attribute>
<xsl:attribute name="_PostalCode">
<xsl:value-of select="''"/>
</xsl:attribute>
</xsl:element>
</xsl:element>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="PARTIES" />
</xsl:otherwise>
</xsl:choose>
<xsl:apply-templates select="EXECUTION" />
<xsl:apply-templates select="CONSIDERATION" />
<xsl:apply-templates select="RECORDABLE_DOCUMENT/_ASSOCIATED_DOCUMENT" />
<xsl:apply-templates select="EMBEDDED_FILE" />
</xsl:element>
</xsl:template>
I was having a similar issue even declaring the namespace on the child elements but was still ending up with
xmlns=""
I thought it was due to the xslt transformation but the string result of the transform was correct and it was when I then transformed the string to a org.w3c.dom.Document that the default namespaces were being added.
Making the DocumentBuilderFactory namespace aware fixed this
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document metadataDOM = db.parse(new ByteArrayInputStream(stringWriter.toString().getBytes()));
Put the calling template and the applied template in the same namespace.
You're re-defining the default namespace with each of those nodes with the 'xmlns=' declaration. Because the PRIA_DOCUMENT
doesn't have a namespace, the output needs to redeclare it as empty, or it would have the same namespace as it's parent. I'd recommend adding in a named namespace to those elements that have one defined, for example:
<pria:DOCUMENT_RECORDATION xmlns:pria="http://pria.org">
and
<as:ONCORE_ERECORD xmlns:as="http://aptitudesolutions.com">
With these named namespaces in place, the blank declaration on the PRIA_DOCUMENT
element becomes unnecessary, and is not added.
