I'm not sure why, but I seem to be having a lot of difficulty getting this to work.

Will someone please post some code I can use to write to an XML file.

I get nothing but errors when I try to copy and paste things from http://irrlicht.sourceforge.net/docu/cl ... riter.html

The code for parsing this file would look like this:

io::IXMLReader* xml = device->getFileSystem()->createXMLReader("config.xml");

Device should be capitalized otherwise it causes an error.

Getting the reader to work isn't a problem, since there is an example in the Meshviewer code, as well as on the API list. I'm still having trouble with the writer though.

I just got this error:

h:\irrlicht-0.6\include\IXMLWriter.h(19) : see declaration of 'irr::io::IXMLWriter'

I put in include IXMLWriter.h in the meshviewer code, thinking perhaps that was the problem. Nope. It doesn't like that either.

h:\irrlicht-0.6\examples\9.Meshviewer\main.cpp(344) : error C2761: 'void irr::io::IXMLWriter::writeXMLHeader(void)' : member function redeclaration not allowed

Someone please tell me what I'm doing wrong. I got everything else working fine I think. No matter what I put in the () it doesn't work.

Eagerly awaiting a reply. I'm sure someone has got the XML writer to work by now... hopefully.

Hi,
the xml-reader is used in the Mesh-viewer example. And in the documentation is the same example.
Be sure you save your xml-file as unicode otherwise he can't read the EOF and repeats infinit the last code (thats the mistake i did

)
And if your problems still exist youre welcome to post a bit more of your code

greetings
Maxi

I have no problems with the READER. I just need to know how to use the WRITER.

I just posted the spelling error for the reader in my post asking about the writer.

Anyway, can you get it to write to a new XML file? If so, please post some code.

Here's some code:

Code: Select all

io::IXMLWriter* xml = Device->getFileSystem()->createXMLWriter("file.xml");
	
xml->writeXMLHeader();
xml->writeLineBreak();

xml->writeComment(L"This is a Comment");
xml->writeLineBreak();

xml->writeElement(L"Element1", false);
xml->writeText(L"Text");
xml->writeClosingTag(L"Element1");
xml->writeLineBreak();

xml->writeElement(L"Element2", true, L"Attr1", L"Val1");

It creates a (unicode) file with the following content:

Code: Select all

<?xml version="1.0"?>

<!--This is a Comment-->
<Element1>Text</Element1>
<Element2 Attr1="Val1" />

Easy?

regards,
jox

And it isn't a spelling mistake for device to be spelt without a capitol, it's a pointer. The pointer could be myGameDevice and it would do the same thing.

exactly!

One little addition to my code example.

Don't forget to add the following at the end. (Because you're using a 'create' function (see docs for grab()/drop())).:

Code: Select all

xml->drop();

13 minutes after my last post someone actually replied. Ack! Why didn't I notice that before?

Anyway, thanks. That works.

Anxiety willing, one of these days I'll actually get something finished.
