Importing XML data with null element

I have an XML file from Jira. I am using KV_MODE = xml and it is importing fine, except for the customfields that Jira supports. Below is a snippet of the custom field codes. KV_MODE = xml will return Approvals Epic Link Rank Testing-Status and NA-1 0|i00fwj: in two separate fields. However, I am interested in searching where Epic Link = NA-1, and they are offset due to the list format Splunk is using. This is being caused by the null elements in the xml. If there was a way to include the null elements, then I can use mvexpand to get the necessary information. Any ideas? ApprovalsEpic LinkNA-1Rank0|i00fwj:Testing Status
