Problems using XMLSchema & XSI with Xerces-C
Hi all,
I've already posted questions here but they've never been answered...I
hope this one will be !
My problem is that I don't manage to write a DOMDocument in a XML file
like I want to : I use a XMLSchema grammar and I can't find out how to
specify it !
Here is the header I want to write :
---
<?xml version="1.0" encoding="utf-8" ?>
<dataset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="XMLSchema.xsd">
---
And here is the only thing I'm able to write with Xerces :
---
<?xml version="1.0" encoding="utf-8" standalone="no" ?><dataset
xmlns="http://www.w3.org/2001/XMLSchema-instance">
---
This is the code I'm using to do this :
---
LocalFileFormatTarget* sortie = new LocalFileFormatTarget(fichier.c_str());
DOMImplementation* impl =
DOMImplementationRegistry::getDOMImplementation(XMLString::transcode("LS"));
DOMWriter* writer = ((DOMImplementationLS*)impl)->createDOMWriter();
DOMDocument* doc = impl->createDocument(
XMLString::transcode("http://www.w3.org/2001/XMLSchema-instance"),
XMLString::transcode("dataset"),
NULL);
doc->setStandalone(false);
doc->setVersion(XMLString::transcode("1.0"));
doc->setEncoding(XMLString::transcode("utf-8"));
// I'll fill in the document here, but later
writer->writeNode(sortie, *doc);
---
What should I do ? Should I use XMLSchemaDescription[Impl] ? If yes, how ??
Thanks for any help.

Thanks a lot !!! This was exactly what I was looking for.
About calling XMLString::release : the "auto"-allocated string/XMLCh
variables aren't freed when their owning function exits ? If not, you
mean I should name every string/XMLCh and release them after ?
Now I have little questions :
- how to make a new line between the <? ... ?> and <root element ...> tags ?
- how to avoid printing the "standalone" attribute ?

DOMDocument* doc = impl->createDocument(
NULL,
XMLString::transcode("dataset"),
NULL);
doc->getDocumentElement()->setAttributeNS(
XMLString::transcode("http://www.w3.org/2001/XMLSchema-instance"),
XMLString::transcode("xsi:noNamespaceSchemaLocation"),
XMLString::transcode("XMLSchema.xsd"));
Also, keep in mind that the memory returned by XMLString::transcode
should be released by calling XMLString::release, or you will have a
memory leak.
