Question

I’m trying to append nodes to an xml file and close the stream at a certain event.
I’ve started with the xmlSettingsExample, but the example saves everything once on key press.

I would like to do something like:

• setup xml (add root note, push tag)
• open file to write xml to
• append xml ‘header’
• while updating append nodes send to a buffer and append to file
• on app exit pop tag, close file

I’ve started like so:

xmlFile.open(ofToDataPath("stream.xml"), ofFile::Append, false);

I imagine on update, after updating my xml I’d do:

xmlFile.writeFromBuffer(xmlBuffer);

and on app exit:

xmlFile.close();

My main question is how do plug my xml object into the xmlBuffer (which is an ofBuffer) ?
I imagine I use the set() method, but not sure how to convert the ofxXmlSettings object to the type accepted by ofBuffer’s set(). Also, is this approach correct or should I be handling this in a different way ?

Thanks!

For the moment I’ve opted for using ofFile to append contents to:

//set this up once
ofFile file;
file.open("file.xml", ofFile::Append);
//update contents multiple times
file << "<data>\n";
//close when done
file.close();
