How to validate the incoming field value and raise an alert message

Question

Dear all,
I have the following structure
If incoming value for the field externalid is empty then i have to raise a alert message to end user "externalid field is empty for the id : id number" and for all incoming values it should work. I used the following udf on field externalid with two arguments
if(externalid.equals(""))
throw new RuntimeException("externalid field empty for the following id : " +id);
else
return externalid;
This is working fine for single record. But for many records(multiple occurences), this logic is not working as if records 2 and 3 fails it is showing exception externalid field is empty for the id : record 2.
how to achieve the tranformation logic ?

Hi Amit,
I have tried the above udf, but still stuck-up.
For the above structure shown in image, i have tested giving the following payload
<?xml version="1.0" encoding="UTF-8"?>
<ns0:upsertRequest xmlns:ns0="http://sap.com/xi/SFIHCM01">
   <sessionId/>
   <upsert>
      <type/>
      <sfobject>
         <id>1</id>
         <businessKeys>1</businessKeys>
         <type>1</type>
         <status>1</status>
         <externalId>1</externalId>
         <username>1</username>
         <firstName>1</firstName>
         <lastName>1</lastName>

         <lastReviewDate/>
         <matrixManagerExternalIds/>
         <defaultLocale/>
         <customManagerExternalIds/>
         <secondManagerExternalId/>
         <loginMethod/>
         <proxy/>
      </sfobject>
      <processingParam>
         <name/>
         <value/>
      </processingParam>
   </upsert>
</ns0:upsertRequest>
No node is creating for success records, instead it throws exception that "externalid field is missing for the id": id     for empty externalid field value in second record.
But my requirement is..... when i process 50 records, records with missing value for field externalid should raise an alert message to end user intimating him to check the externalid field for particular id. If the value for externalid field is present in incoming record/payload, then it should be passed to target system.
How can i implement this logic ?
