This subprocedure is used to clean up after utilizing the DOM parsing API RXS_OpenDom(). It only needs to be called on the primary DOM data structure. You should not attempt to close a DOM data structure created as a result of calling RXS_ParseDomToDom().

This subprocedure must be called at the end of all DOM parsing to properly free up memory and avoid performance impacts.

The RXS_ParseDomDS_t data structure previously initialized and used as part of RXS_OpenDom()

Example Code

**FREE // This example demonstrates completing a DOM parsing session by using // RXS_CloseDom on the RXS_ParseDomDS_t datastructure originally returned // by RXS_OpenDom. It's important to call RXS_CloseDom once DOM parsing has // been completed to free memory used by the DOM parser.
