Simple XML source code defines dashboard and form structure, elements, and behavior.
Use the Dashboard Editor to build or edit dashboards in Simple XML.
You can also export Simple XML dashboards to HTML if you are building apps with the Splunk Web Framework.
Note: As of software version 6.3, advanced XML and the Module System are deprecated. Use Simple XML to create new dashboards or forms. Migration of existing Advanced XML dashboards or forms to Simple XML is encouraged.
