Hi all
WMB 7.0.0.6
I have following xml

Code:

<additionalService>
<typeName>PRC</typeName>
            <actionCode>RNCRD</actionCode>
         </additionalService>
         <additionalService>
            <typeName>NFC</typeName>
            <code>AUTHORIZATION</code>
            <params>
               <key>AddressType</key>
               <value>SMS_AUTH</value>
            </params>
            <params>
               <key>Language</key>
               <value>BLG</value>
            </params>
            <params>
               <key>Email</key>
               <value>example@example.com</value>
            </params>
            <params>
               <key>Phone</key>
               <value>+00000000000</value>
            </params>

            <params>
               <key>ActionCode_SMS</key>
               <value>DIF_ACCHOLDER_SMS_ON</value>
            </params>
            <params>
               <key>ActionCode_EMAIL</key>
               <value>DIF_ACCHOLDER_EMAIL_ON</value>
            </params>
         </additionalService>

         <additionalService>
            <typeName>NFC</typeName>
            <code>PAYMENT</code>
            <params>
               <key>AddressType</key>
               <value>SMS_PAYMENT</value>
            </params>
            <params>
               <key>Language</key>
               <value>BLG</value>
            </params>
            <params>
               <key>Email</key>
               <value>example@example.com</value>
            </params>
            <params>
               <key>Phone</key>
               <value>+00000000000</value>
            </params>
         </additionalService>

in mapping node FOR node I want to make XPath meaning of
$source/additionalService/params[../typeName='NFC']

Those give expression error.

Can somebody help?

Your XPath predicate is invalid, predicates filter a set of repeating elements by applying an expression on it's children

Code:

parent[child expression]

As "typeName" is a child of the repeating element "additionalService" a valid predicate would be

Code:

$source/additionalService[typeName='NFC']/params

This would provide a node set containing all "params" elements that are a child of an "additionalService" element that has typeName='NFC'

I believe what is really needed is more complex:
What I would want here are all the children of $source/additionalService, where typeName='NFC'. This would also give me the "code" that qualifies the list of parameters...

All complex stuff is comming from Mapping Node not from XPATH syntax. As soon as I know
from

https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014484872

XPath syntax in the Mapping node does not support predicates

Please confirm?!
