`D RXS_ParseDomToXml... D PR Extproc('RXS_ParseDomToXml') Opdesc D Like(RXS_Var16Mv_t) D Rtnparm`	Returns the XML subsection retrieved by the specified XPath.
`D XPath Like(RXS_Var8Kv_t) Const D Options(*Varsize)`	XPath used to determine which nodes are retrieved into the RXS_ParseDomDS_t return data structure.
`D DS Like(RXS_ParseDomDS_t) D Options(*Varsize)`	RXS_ParseDomDS_t data structure, e.g. the “parent” structure.

Example 1

*--------------------------------------------------------------
* This example demonstrates retrieving the raw XML data from a specified  
*  XPath and storing it in a character field.
* This example uses IBM i 7.1+ prototypes for most calls; refer to
*  the individual documentation for these subprocedures for the 
*  6.1 prototypes.
