I'm using the Views XML Backend to pull in data from a URL.
I'd like the user to be able to optionally be able to select a value for a single field and display the record for that selection. For example, if the XML had information for different offices, I'd like to show the user the records for all of the offices, but allow them to pick a specific office from the list to see only the record for that office. The URL can take a query string or POST parameter with the search terms, but I'm fine with letting the search be done by Drupal.
How do I achieve this in a way that leverages Drupal's capabilities, as opposed to doing the filtering in jQuery?
I already have the view created, but I only see exposed filter options I saw were XML: Numeric, XML: Text, and Global: Combine fields filter. What I'm looking for is something like XML: Pick a Value.
