Load multiple xml files into one sketch [proXML]

in Contributed Library Questions • 1 year ago

Hallo,

I'm just wondering if it is possible to load more than one xml file into a sketch.

I have several xml files of this structure.

<?xml version="1.0" encoding="ISO-8859-1"?>
<pulses>
<circle>
<data posX="230" posY="121" col="200" rad="20"/>
</circle>
<circle>
<data posX="139" posY="201" col="130" rad="23"/>
</circle>
<circle>
<data posX="230" posY="243" col="54" rad="17"/>
</circle>
</pulses>

When executing the script it only loads and prints out all attributes of the first xml file.

Is there a way how to load several xml files separately into one sketch? This would be great!!!!

Thanks in advance!!

XMLInOut xmlIO;
XMLInOut xmlIO1;

void setup() {
size(400, 400);

myList1 = element;
}
void draw() {
}
// ----------------------------------------------------------------------

void readData () {
xmlIO = new XMLInOut(this);
try {
xmlIO.loadElement("test.xml");
}
catch (Exception e) {
xmlEvent(new proxml.XMLElement("myList"));
}
while (myList == null) {
}
proxml.XMLElement[] allData = myList.getChildren();
for (int i = 0; i< allData.length; i++) {
proxml.XMLElement data = allData[i];
proxml.XMLElement param = data.getChild(0);
if (!param.getName().equals("data")) continue;
String posX, posY, col, rad;
posX = param.getAttribute ("posX");
posY = param.getAttribute("posY");
col = param.getAttribute("col");
rad = param.getAttribute("rad");
println("posX:" + posX + " " + "posY:" + posY + " " + "col:" + col + " " + "rad:" + rad);
}
}
void readData1() {
xmlIO1 = new XMLInOut(this);
try {
xmlIO1.loadElement("test1.xml");
}
catch (Exception e) {
xmlEvent(new proxml.XMLElement("myList1"));
}
while (myList1 == null) {
}
proxml.XMLElement[] allData = myList1.getChildren();
for (int i = 0; i< allData.length; i++) {
proxml.XMLElement data = allData[i];
proxml.XMLElement param = data.getChild(0);
if (!param.getName().equals("data")) continue;
String posX, posY, col, rad;
posX = param.getAttribute ("posX");
posY = param.getAttribute("posY");
col = param.getAttribute("col");
rad = param.getAttribute("rad");
println("posX:" + posX + " " + "posY:" + posY + " " + "col:" + col + " " + "rad:" + rad);
}
}

Why do you make twice the same function? Make one, with parameters allowing some elements (the file name, etc.) to change.
And you probably need some global variable indicating in which list the elements must go in the xmlEvent() function. Perhaps an index in an array.

Hey phi.lho,

thanks for your quick reply.

sorry, I don't get this to work. It's obvious to me that writing twice the same function isn't a clever way to do this.;-)

So I put the filenames into Strings.

String filename1 = "test.xml";
String filename2 = "test1.xml";
xmlIO = new XMLInOut(this);
try {
xmlIO.loadElement(filename1);
}
catch (Exception e) {
xmlEvent(new proxml.XMLElement("myList"));
}

Hm, what do you mean by putting a global variable to indicate in which list the elements must go?

I was more thinking about parameters to a function, not global variables, which doesn't change the problem...
And think in arrays, instead of n named variables, and n booleans, which complicate the issue instead of simplifying it.

Quick question here... wasn't proXML included in the Processing core a while back? Is there a difference between it and the Core XMLElement?

No, proXML is separate of Processing's XML, although for such usage, base XML from Processing should be enough.

Hey all,

I still don't know how to work this out in a really nice way. But the way I tried it above with two functions works perfectly fine when adding some boolean or so to the xmlEvent function.

void xmlEvent(proxml.XMLElement element) {
if (xml1 == true) {
myList = element;
}
if (xml2 == true){
myList1 = element;
}
}

The true and false setting of each boolean is placed at the end of each readData() function.

void readData () {
xmlIO = new XMLInOut(this);
try {
xmlIO.loadElement("test.xml");
}
catch (Exception e) {
xmlEvent(new proxml.XMLElement("myList"));
}
while (myList == null) {
}
proxml.XMLElement[] allData = myList.getChildren();
for (int i = 0; i< allData.length; i++) {
proxml.XMLElement data = allData[i];
proxml.XMLElement param = data.getChild(0);
if (!param.getName().equals("data")) continue;
String posX, posY, col, rad;
posX = param.getAttribute ("posX");
posY = param.getAttribute("posY");
col = param.getAttribute("col");
rad = param.getAttribute("rad");
println("posX:" + posX + " " + "posY:" + posY + " " + "col:" + col + " " + "rad:" + rad);
}
xml2 = true;
readData1();
}

I know this is a totally crappy solution, but it works...
