Currently we succesfully parse MQ messages with IBM XMLPR500 in this way.
first we get the lengh of the message:
MQGMO.GMOPT = GMWT; // MQGMO_WAIT
MQGMO.GMOPT += GMLK; // MQGMO_LOCK
MQGMO.GMOPT += GMATM; // MQGMO_ACCEPT_TRUNCATED_MSG
MQGMO.GMOPT += GMCONV; // MQGMO_CONVERT
MQGMO.GMOPT += GMBRWF; // MQGMO_BROWSE_FIRST
MQMD.MDMID = MINONE; // MQMI_NONE
MQMD.MDCID = CINONE; // MQCI_NONE
BUFLEN = 0;
BUFPTR = %alloc(1);
MQGET(HCONN: HQGET: MQMD: MQGMO: BUFLEN: BUFPTR:
MSGLEN: CMPCOD: REASON);
then we get the message
BUFLEN = MSGLEN;
BUFPTR = %realloc(BUFPTR:BUFLEN);
MQGMO.GMOPT = GMNWT; // MQGMO_NO_WAIT
MQGMO.GMOPT += GMMUC; // MQGMO_MSG_UNDER_CURSOR
MQGMO.GMOPT += GMCONV; // MQGMO_CONVERT
MQMD.MDMID = MINONE; // MsgId selector
MQMD.MDCID = CINONE; // CorrelId selector
MQMD.MDCSI = 280; // CCSID locale
MQGET(HCONN: HQGET: MQMD: MQGMO: BUFLEN: BUFPTR:
MSGLEN: CMPCOD: REASON);
then we call a program that parses the message only to get the method
MQ_PARSE (BUFPTR:MSGLEN);
This program parses the document and finds the method to call (here we have
something like
<Process>XYZ</Process> where XYZ is the program that actually parses the
specific message:
QxmlInit(envData);
DomParse =QxmlXercesDOMParser_new(PenvData);
MemBufInputSource = QxmlMemBufInputSource_new(
MSGPTR:MSGLEN:buf:280:0:0);
QxmlXercesDOMParser_parse_InputSource(DomParse:MemBufInputSource);
DomDoc = QxmlXercesDOMParser_getDocument(DomParse);
GetTagOpt = %alloc(256);
%str(GetTagOpt:256) = 'Process';
NodeList = QxmlDOMDocument_getElementsByTagName
(DomDoc:GetTagOpt:Qxml_CHARSTR:0);
Node = QxmlDOMNodeList_item(NodeList:0);
if QxmlDOMNode_isNull(Node) = Qxml_NODNOTNUL;
if QxmlDOMNode_getNodeType(Node) = Qxml_ELMNT_NOD;
Child = QxmlDOMNode_getFirstChild(Node);
if QxmlDOMNode_getNodeType(Child) = Qxml_TEXT_NOD;
NodeValue =QxmlDOMNODE_getNodeValue(Child);
QxmlTranscode(NodeValue:Qxml_UNICODE:oStgP:BpP:Bap:280);
Method = %str(oStgP);
endif;
endif;
endif;
and then call a program (in this example XYZ) that actually retrieves the
elements from the parsed document:
call(e) Method
parm DomDoc
parm MSGPTR
parm MSGLEN
