RE: XML Toolkit concatenating strings on multiple calls

Henrik,

You are correct. If I can't get an answer to what's going wrong in the parser that's what I'm going to do.

We are trying to move away from hard coding XML creation and using a parser to try and cut down on errors.

Hi Rick,

I don't know anything about XML toolkit, but I'm curious to know what all this
code does and what the result in XMLOut are, as I read it, it is a single XML
node with attributes that then are added to a dataqueue.

If so, you could easily just build the node in one single RPGLE statement like

xmlOut = '<Audit'
+ ' letterID="' + %trimR(letterId) + '"'
+ ' sourceSystem="' + SourceSystem + '"'
+ ' targetSystem="' + TargetSystem + '"'
+ ' auditDate="' + OracleTmsp + '"'
+ ' />');

Maybe I didn't make this as clear as I should have.

The read from the data queue is not causing concatenation that is
fine. It is the creation of the XML string using the toolkit that
results in concatenation. The result of building the XML string for
each iteration returns a string containing every XML string created up to

that point.

I am using the XML Toolkit 5.6(?) to create an XML string. The
program is processing entries from a data queue until the queue is
empty. The XML is being formed properly but the resulting string
is being concatenated to the previous result. For example, if
there are three entries on the queue I will get the correct XML
string on the first call, the correct XML for the second entry
appended to the first XML string on the second call, and the
correct XML for the third entry appended to the XML string
containing the first two entries on the third call.

I've not had that problem. I'm using a construct like this:
xmlData = "";
KeyedDataQueue dq = new KeyedDataQueue(iHost, pathToQueue);
DataQueueEntry dqe = null; do {
dqe = dq.read(dataQueueKey, 1, "EQ");
if (dqe != null) xmlData += dqe.getString(); } while(dqe !=
null); dataExists = (xmlData.length() > 0);
