When I try to get the "standalone" attribute value from the DOM after loading
the XML document from a file it *always* returns "false."
I have a demo XML file containing two lines as:
// ################ XML File ##################
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
And the code snippet is as follows:
// ################ CODE SNIPPET ##################
private void checkXMLDecl() {
// Create a factory object for creating DOM parsers
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
Document xmlDOM = null;
try {
// Now use the factory to create a DOM parser
builder = factory.newDocumentBuilder();
xsDOM = builder.parse(xsdFile);
// Get the xml declaration
System.out.println("version = [" + ((CoreDocumentImpl)xsDOM)
.getVersion() + "]");
System.out.println("encoding = [" + ((CoreDocumentImpl)xsDOM)
.getEncoding() + "]");
// ########################################################
// The getStandalone() method does NOT work
if ( ((CoreDocumentImpl)xsDOM).getStandalone() )
System.out.println("standalone is true");
else
System.out.println("standalone is false");
}
catch (Exception ex) {
}
}
I have tested with Xerces v2.0.2, v2.2.1, and v2.4.0, but all three returns
the same result, "false."
Any comments?
