Transforming the REST XML message to SOAP message - OSB
This post will explain how to Transform the REST XML message to SOAP message in OSBWhile receiving the response from REST interface with the content type as application\xml, the input XML will be plain without the target namespace specified.
But if you are invoking the BPEL with this message the BPEL cant perform any xpath operations on this message without target namespace.The target namespace should be added to the message.
The XSLT can be used to add the name space to the XML message but before performing this operation the SOAP envelope of the body variable should be removed
After removing the namespace the XML should be assigned to the body variable to send to target system.
Follow the below steps to achieve the same:
Remove SOAP Envelope:
The below XSLT will help as to remove the namespace from the XML.Create a XSLT resource from SB console.
Add a Assign activity with the XSLT resource
Assign the output to a temp variable - var1.
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="soapenv:*">
<xsl:apply-templates select="@* | node()" />
</xsl:template>
</xsl:stylesheet>
Adding the Namespace:
The below XSLT will help as to add the target namespace to the XML.Create a XSLT resource from SB console.
Add a Assign activity with the XSLT resouce to add the namespace to the variable var1
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*" />
</xsl:copy>
</xsl:template>
<xsl:template match="*">
<xsl:element name="ns:{local-name()}" namespace="http://www.tr.com/ns/2013/10/16/EAI/AAA/LicenseManagementResp">
<xsl:apply-templates select="node()|@*" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
