  • 1.  Why dp:url-open is adding additional namespace automatically?

    Dear All,

    I'm encountering an issue with the addition namespaces were added to my input XML message in the dp:url-open. 
    Here in my sample input message

     <Message>                           
      <Name>Jhon</Name>
      <Date>2025-03-09T11:54:03</Date>                      
</Message>

 <xsl:variable name="response">
       <dp:url-open target="{$url}" response="responsecode" content-type="text/xml" http-method="POST" http-headers="$httpHeaders">
             <xsl:copy-of select="$inputXML"/>
      </dp:url-open>
 </xsl:variable>

    but dp:url-open is posting message to the backend as below:

    Here it is adding following namespaces to the request xmlns:dp="http://www.datapower.com/schemas/management" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:json="http://www.ibm.com/xmlns/prod/2009/jsonx". Due to these namespaces backend server is refusing the message.

     <Message xmlns:dp="http://www.datapower.com/schemas/management" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" 
                  xmlns:json="http://www.ibm.com/xmlns/prod/2009/jsonx">                           
      <Name>Jhon</Name>
      <Date>2025-03-09T11:54:03</Date>                      
</Message>

    Is there a way to stop adding these namespaces to the request in dp:url-open?

    Thanks!

    Have you attempted to put 'exclude-result-prefixes="dp env json"' in your stylesheet element declaration?

    Yes, @Joseph Morgan, I have already added it.

    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dp="http://www.datapower.com/extensions" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:json="http://www.ibm.com/xmlns/prod/2009/jsonx" xmlns:str="http://exslt.org/strings" extension-element-prefixes="dp str" exclude-result-prefixes="dp json env str" version="1.0"> </xsl:stylesheet>

    Interesting.  So, I found this XSLT in my box-of-tricks for DataPower.  I know I haven't used this in a long while, but there must be a reason I wrote it.  You may have to make a few changes to your process to generate the message and send it via a Results action (like I said, I forgot why I wrote it...), but, this little transform removes namespaces from an XML message:

    <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"/>
  
 <!-- keep comments -->
 <xsl:template match="comment()">
    <xsl:copy>
      <xsl:apply-templates/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*">
    <!-- remove element prefix -->
    <xsl:element name="{local-name()}">
      <!-- process attributes -->
      <xsl:for-each select="@*">
        <!-- remove attribute prefix -->
        <xsl:attribute name="{local-name()}">
          <xsl:value-of select="."/>
        </xsl:attribute>
      </xsl:for-each>
      <xsl:apply-templates/>
    </xsl:element>
  </xsl:template>
</xsl:stylesheet>

    Thank you @Joseph Morgan for the suggestion. 
    How can I intercept request body with in the url-open? In my original message does not contains namespaces.

    Sorry, I should have been more clear.   You'd have to stop using the dp:url-open.

    Build the message without the explicit name-spacing in some kind of transform (I suspect that's what you're doing).   Then send that to the back end.   With that, I don't think DataPower would modify it further.   If it does, you may have to use something like my little trick above.  But, I think if you just build the message with a transform as the last thing on the processing rule, you should be OK.

    Client to Server rule:    INPUT -> other actions -> transform to build message (nothing else)
