CciElement* cpiParent( int* returnCode, const CciElement* targetElement);
If successful, the address of the requested syntax element is returned. If there is no parent element, zero is returned. If an error occurs, zero (CCI_NULL_ADDR) is returned and the returnCode parameter indicates the reason for the error.
This example is taken from the sample parser file BipSampPluginParser.c (lines 116 to 173):
void* parseNextItem( CciParser* parser, CciContext* context, CciElement* element ){ void* endMarker; void* startMarker; PARSER_CONTEXT_ST* pc = (PARSER_CONTEXT_ST *)context; CciElement* returnElement = element; CciElement* newElement; size_t markedSize; const CciChar* data; int rc; if (pc->trace) /* Skip any white space */ skipWhiteSpace( (PARSER_CONTEXT_ST *)context ); /* Are we at the end of the buffer? */ if (pc->iIndex == pc->iSize) return(0); } /* Are we within a tag? */ if (pc->iInTag) { if (pc->iCurrentCharacter == chCloseAngle) { /* We have reached the end of a tag */ pc->iInTag = 0; advance( (PARSER_CONTEXT_ST *)context, parser ); } else if (pc->iCurrentCharacter == chForwardSlash) { /* We may have reached the end of an empty tag */ advance( (PARSER_CONTEXT_ST *)context, parser ); if (pc->iCurrentCharacter == chCloseAngle) { pc->iInTag = 0; advance( (PARSER_CONTEXT_ST *)context, parser ); cpiSetElementCompleteNext(&rc, element, 1); returnElement = cpiParent(&rc, element); }
