Software ID Tags (SWIDTags) are XML files that contain metadata about software that is installed on the machine. The FlexNet Inventory Agent scans Inventory Devices for both the presence of a SWIDTag and the data within the SWIDTag. This information is stored in the Inventory file (NDI file) that the agent generates. The data from the SWIDTag is encoded within the NDI file generated by the agent using Base64 encoding. 

SWIDTag data in the NDI file appears in the following format:

The MD5 is a unique hash value used to ensure that Swidatags found on different machines are identical. 
The Path value is the location on the machine where the SWIDTag file was found.

The data within the <Value> Tags are the contents of the SWIDTag encoded in Base64. Several web-based tools are available to decode Base64 encoding. One option is: https://www.base64decode.org/

Using this web-based tool, the <Value> tag above decodes to the following: 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
