D RXS_OpenDom     PR                  Extproc('RXS_OpenDom') Opdesc
D                                     Like(RXS_ParseDOMDS_t)

Returns an RXS_ParseDOMDS_t which contains information and pointers used by subsequent DOM parsing APIs.

D  Xml                                Like(RXS_Var16Mv_t) Const
D                                     Options(*Omit:*Varsize)

Chunk of XML to be used for subsequent DOM operations.

D  DS                                 LikeDS(RXS_OpenDomDS_t)
D                                     Options(*Nopass:*Varsize)

Holds RXS_OpenDomDS_t used to set up initial DOM parsing options.

Example Code

* This example demonstrates configuring DOM parsing using a RXS_ParseDOMDS_t
*  datastructure.
