D                                     Options(*Varsize)

XPath used to determine which nodes are retrieved into the RXS_ParseDomDS_t return data structure.

D  pDS                                LikeDS(RXS_ParseDomDS_t)
D                                     Options(*Varsize)

RXS_ParseDomDS_t data structure, e.g. the “parent” structure.

Example Code

* This example demonstrates retrieving a text value 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.
