No data displayed when extract fields from xml data in a log file using xpath

[3618475]

I am using Splunk to extract a number of fields from xml data this is contained in a log file.
The file is very large. This is part of it.

This query selects the xml part text in the logging file and some of the fields are extracted and I can add to a table. (not including the source and sourcetype..)

| xmlkv | table purchCostReference, eventType, carrier, billingMethod

But need more fields that are child elements within the xml data. One of them is the numberCode. I am trying to use xpath to extract these additional fields.

| xmlkv | xpath
"//tmsTrip/purchasedCost/purchasedCostTripSegment/origin/ns2:numberCode"

outfield=Origin | table
purchCostReference, eventType,
carrier, billingMethod, Origin

But no Origin data is returned when I add the field to the table. There is no error. The Origin column is empty.
What am I doing wrong with the xpath command that it is not showing any data?
