Re: XML Toolkit concatenating strings on multiple calls

Neill,

I think you are on to something. I was thinking the outXMLDocument procedure was part of the parser and kept skipping over it. Anyway, the code is here http://code.midrange.com/f355dd75e7.html. The return value of myString is defined globally and I'm not seeing it get cleared in this procedure.

Hi Rick

It is frustrating, I had to use the c++ documentation that ships with the
product to figure out how things work.

The membuffformattarget among other targets are used by the
Qxml_XmlFormatter object. The xmlformatter object takes care of writing to
the target in an xml safe manner. I.e converts < to &lt; etc. The new part
means it's the procedural wrapper over the c++ constructor.

Anyway I think the answer lies in the OutXmlDocument procedure can we
see the source for that?

Thanks

Neill

Neill,

No, I am not using qxml_membufformatTarget_new. Part of my

frustration with using the toolkit is lack of informative documentation. The
only documentation we have lists the procedure calls and parameters but I
haven't been able to find descriptions or examples. I've tried searching
InfoCenter and Google too without success but it's always possible I didn't
search for the right phrase.

What is qxml_membufformatTarget_new?

The XML calls can be found here

http://code.midrange.com/3f349cf405.html.

Hi Rick

I have done a lot of work with this framework so i might be able to help

you.

But I'd need to see some code, are you using
qxml_membufformatTarget_new?

More specifically are you creating a new one for each render?

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);
