Re: XML Toolkit concatenating strings on multiple calls -- RPG400-L

Rick,

to me you are creating very hard to read code that actual dosn't simplify or
cut
down errors.

The basics that I made an example of, requires more XML skills and isn't
stable
because it dosn't encode strings with special characters.

However there are other alternatives, my own open source project has a
"simple"
XML node support with a subprocedure generating the node:

xmlNode(id:attributes:data);

or if you prefer the syntax of XML Toolkit I could build:

xmlNodeInz('id');
xmlNodeAddAttr('attribute':value);
xmlNodeAddAttr('attribute':value)
xmlNodeAddData(data)
xmlNodeAddToBuffer(); // adds to a internal XML buffer
or
xmlData = xmlNodeGet(); // returns the result

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);
