It can also be ** used as clean up function to delete left over data from previous parse. ** This clean up function is typically used when application runs out of ** resource and decides to discard extra xml data received. ** ** Parameters p_xml_state: pointer to a xml parser initialized by XML_EvtRptInit(). ** xml_data: valid pointer to OBEX list data in xml format. ** xml_len: length of the package, must be non-zero value. ** dst_data: valid pointer to the buffer for holding converted folder entry name. When dst_data is NULL, clean up all remaining data in the parser. ** dst_len: pointer to the length of dst_data buffer, its carry out value ** is the number of bytes remaining buffer.When dst_len is NULL, ** it will cause to flush the internal data in the parser. ** num_entries: current number of entries, in the end it is the total number of entries ** ** Returns tXML_EVT_RPT_RES (see xml_erp.h) ** XML_PENDING: parsing not completed ** XML_END_LIST: found /folder-listing but no final flag detected ** XML_EVT_RPT_OUT_FULL: reached max_entry -> do not call parser anymore!!! dump data ** XML_EVT_RPT_DST_NO_RES : run out of dst buffer resource while ** some xml data still remains. **************************************************************************************/ tXML_EVT_RPT_RES XML_EvtRptParse( tXML_EVT_RPT_PARSER *p_xml_state, UINT8 *xml_data, UINT16 xml_len, UINT8 *dst_data, UINT16 *dst_len, UINT16 *num_entries ) { tXML_OS xos; BOOLEAN is_remain = TRUE; tXML_MUL_STATE *p_xml = &p_xml_state->xml; tXML_EVT_RPT_STATE *p_st = &p_xml_state->xml_user_data; tXML_EVT_RPT_RES x_res = XML_EVT_RPT_OK; tXML_RESULT res = XML_NO_PROP; UINT16 max_num_prop = GKI_BUF3_SIZE/sizeof(tXML_PROP); /* i hope this is sufficient for 1 */ #if (defined(EVT_RPT_DEBUG_XML) && EVT_RPT_DEBUG_XML == TRUE) int xx; UINT8 dbg_buf[EVT_RPT_DEBUG_LEN]; tXML_STR str; #endif XML_TRACE_DEBUG0("[xml evt_rpt] XML_EvtRptParse"); /* if dst_data is NULL, clean up remaining data */ if (!dst_data || !dst_len) { /* clean out remained xml data left over from last parse */ if (p_xml_state->xml_user_data.p_prop ) { GKI_freebuf( p_st->p_prop ); p_st->p_prop = p_st->offset_prop = NULL; p_st->prop_num = 0; } #if (EVT_RPT_DEBUG_XML == TRUE) XML_TRACE_DEBUG0( "[xml evt_rpt] XML_EvtRptParse() Clean up left over!"); #endif return x_res; } /* if illegal OBEX data or dst buffer pointer received, return ERROR */ if (xml_len == 0 || !xml_data) { return XML_EVT_RPT_ERROR; } /* XML_EvtRptParse receive new xml data, allocate buffer to hold parsed prop */ if (p_st->offset_prop == NULL) { #if (EVT_RPT_DEBUG_XML == TRUE) XML_TRACE_DEBUG0( "[xml evt_rpt] XML_EvtRptParse() Receive New Data!"); XML_TRACE_DEBUG2( "[xml evt_rpt] XML_data start[%x] end [%x]",xml_data, xml_data+xml_len); #endif is_remain = FALSE; if ( NULL!= (p_st->p_prop = (tXML_PROP *)GKI_getbuf( GKI_BUF3_SIZE ) ) ) { /* pointing next prop to be converted into file entry */ p_st->prop_num = 0; } else { GKI_freebuf( p_xml_state ); x_res = XML_EVT_RPT_NO_RES; return x_res; } } #if (EVT_RPT_DEBUG_XML == TRUE) else { XML_TRACE_DEBUG0( "[xml evt_rpt] XML_EvtRptParse(): Keep cleaning up old xml data !"); } #endif /* update the data address */ xos.p_begin = xml_data; xos.p_end = xml_data + xml_len; while ( res == XML_NO_PROP ) { /* if no remaining data in p_st->p_prop, parse new xml data */ if (!is_remain) { p_st->max_num_prop = max_num_prop; p_st->prop_index = 0; res = XML_MulParse( p_xml, &xos ); #if (EVT_RPT_DEBUG_XML == TRUE) XML_TRACE_DEBUG4( "xml_evt_rpt_parse obj: %x, max: %d, num: %d, res: %d", p_st->obj, max_num_prop, p_st->prop_index, res); if (res != 0) { XML_TRACE_DEBUG1( "XML_MulParse Parsing: %d !!!", res); } for (xx=0; xxprop_index; xx++) { if ( p_st->p_prop[xx].name < XML_EVT_RPT_MAX_ID ) { str.p = p_st->p_prop[xx].p_data; str.len = p_st->p_prop[xx].len; xml_erp_debug_str(&str, dbg_buf); XML_TRACE_DEBUG5( "[xml evt_rpt] parsed: index[%d]:%d:%s: %s(%d)", p_st->prop_index-xx, p_st->p_prop[xx].level, xml_erp_ttbl[p_st->p_prop[xx].name].p_name, dbg_buf, p_st->p_prop[xx].len); } else { XML_TRACE_DEBUG3( "[xml evt_rpt] internal prop: %d:%d:%d", xx, p_st->p_prop[xx].level, p_st->p_prop[xx].name ); } } #endif p_st->prop_num = p_st->prop_index ; p_st->offset_prop = p_st->p_prop; } else { /* This is left over data, pick up the result from the previous parse */ res = p_xml->pars_res; } if ( res != XML_OBJ_ST_EMPTY ) { x_res = xml_erp_int_fill_evt_data( p_st->obj, p_st, &p_st->offset_prop, &p_st->prop_num, &dst_data, dst_len ); if ( (XML_EVT_RPT_OK == x_res) && (XML_NO_END == res) ) { /* XML_NO_END means that the xml is not completly finished and fill returns ok when when partial filling has been ok */ x_res = XML_EVT_RPT_PENDING; } /* all parsed xml data has been converted into file entry */ /* or exceed max entry number , break the parsing loop */ if (XML_EVT_RPT_OUT_FULL != x_res && XML_EVT_RPT_DST_NO_RES != x_res) { is_remain = FALSE; } else break; } } /* while */ /* free property table. at next call a new one is allocated */ if ((x_res != XML_EVT_RPT_DST_NO_RES && p_st->p_prop) || XML_EVT_RPT_OUT_FULL == x_res) { GKI_freebuf( p_st->p_prop ); p_st->p_prop = NULL; p_st->offset_prop = NULL; } if ( x_res != XML_EVT_RPT_DST_NO_RES && p_st->ended) { /* this should happen on the same time as final flag in fact */ x_res = XML_EVT_RPT_END_LIST; /* found closing /evt_rpt-listing */ } *num_entries = p_st->current_entry; /* report number of entries found. only when ended is true application really should be interested!
