How to extract unique values from XML data?

Engager

I have a splunk log entry that contains XML. I need to extract all the unique values for Customer City, and show them, such as what I would do in Unix with sort|uniq.

Is this possible in splunk?

<request>
  <CustomerName>Smith</CustomerName>
  <CustomerAddress>111 Elm Street</CustomerAddress>
  <CustomerCity>Allentown</CustomerCity>
</request>

Try this:

| stats count | eval xml = "<request><CustomerName>Smith</CustomerName><CustomerAddress>111 Elm Street</CustomerAddress><CustomerCity>Allentown</CustomerCity></request>,<request><CustomerName>Smith</CustomerName><CustomerAddress>111 Elm Street</CustomerAddress><CustomerCity>Allentown</CustomerCity></request>,<request><CustomerName>Smith</CustomerName><CustomerAddress>111 Elm Street</CustomerAddress><CustomerCity>Not Allentown</CustomerCity></request>" | makemv xml delim="," | mvexpand xml | rename xml as _raw
| spath | dedup request.CustomerCity | table request.CustomerCity

The first block just sets up dummy data, the meat is the last three commands. spath grabs the fields from your XML, dedup does the sort|uniq part, table picks out just that column to show.
