ProcessingInstruction Interface

Table 4-11 summarizes the methods of available through the ProcessingInstruction interface.

XmlDomGetPIData

Returns the content (data) of a processing instruction (in the data encoding). If the node is not a ProcessingInstruction, returns NULL. The content is the part from the first non-whitespace character after the target until the ending "?>".

oratext* XmlDomGetPIData(
   xmlctx *xctx, 
   xmlpinode *pi)

xctx

IN

pi

IN

(oratext *) processing instruction's data [data encoding]

XmlDomGetPITarget

Returns a processing instruction's target string. If the node is not a ProcessingInstruction, returns NULL. The target is the first token following the markup that begins the ProcessingInstruction. All ProcessingInstructions must have a target, though the data part is optional.

oratext* XmlDomGetPITarget(
   xmlctx *xctx,
   xmlpinode *pi)

xctx

IN

pi

IN

(oratext *) processing instruction's target [data encoding]

XmlDomSetPIData

Sets a ProcessingInstruction's content, which must be in the data encoding. It is not permitted to set the data to NULL. If the node is not a ProcessingInstruction, does nothing. The new data is not verified, converted, or checked.

   xmlctx *xctx, 
   xmlpinode *pi, 
   oratext *data)
