I'm using the Web Service Node in the PFI. My WS returns one or more records in the XML data stream. How do I detect the last record or EOF so I know when to stop processing. In PFI WS node, you can access each data element from WS using the array (0). Is there a max array counter that the PFI tool provides for us to use?

thanks,
Tom.

I found the answer I needed it. WS returns a XML Object with one or multiple elements. To find out how many elements in the returned xmlOject, you would need to use the length() function. for example: xmlOject.length()
This will return the max number of elements in your Oject. You would then create a JavaScript routine to loop through these elements to access your xml data fields returned from the WS. e.g. xmlOject::dataElement(x).
