验证DataPower中的一部分请求

Question

I have WSDL which can be used to validate complete XML and part of XMLs

MY XML :

<Request>
     <Part> .. </part>
     <Part> .. </part>
     <Part> .. </part>
     <Part> .. </part>
     <Part> .. </part>
     <Part> .. </part>
     <Part> .. </part>
</Request>

I have configured validation action which is validating complete and throwing as one or more part is having invalid data.

Requirement is : I have to validate only the part in the above request and remove invalid part before sending to backend.

Any help??

This can be done by using extension element / function in the XSLT.

Skeleton:

<xsl:template match=Request>
<xsl:copy>
<xsl:for-each select="Part">
 <xsl:if test="dp:schema-validate($schema,.) !=''">
   <xsl:copy-of select="."/> 
 </xsl:if>
</xsl:for-each>

schema-validate() : Performs a schema validation.
Namespace declaration : xmlns:dp="http://www.datapower.com/extensions"

Syntax :dp:schema-validate(schema, nodeset)

Parameters : schema : (xs:string) Identifies the XSD schema to perform the validation. nodeset:(xs:node-set) Identifies the node set that contains the XML content to validate. All arguments are passed as XPath expressions.

Results :the validated node set.
