: "standalone " in the XML declaration, <?xml ... ? > 2003-05-11 - By Michael Rafael Glavassevich
It looks like a bug in the parser.
Changing lines 859 & 865 in Revision 1.86 of
org.apache.xerces.parsers.AbstractDOMParser as shown below should fix the
problem.
public void xmlDecl(String version, String encoding, String standalone,
Augmentations augs)
throws XNIException {
if (!fDeferNodeExpansion) {
// REVISIT: when DOM Level 3 is REC rely on Document.support
// instead of specific class
if (fDocumentImpl != null) {
fDocumentImpl.setVersion(version);
fDocumentImpl.setEncoding(encoding);
- fDocumentImpl.setStandalone("true".equals(standalone));
+ fDocumentImpl.setStandalone("yes".equals(standalone));
}
}
else {
fDeferredDocumentImpl.setVersion(version);
fDeferredDocumentImpl.setEncoding(encoding);
- fDeferredDocumentImpl.setStandalone("true".equals(standalone));
+ fDeferredDocumentImpl.setStandalone("yes".equals(standalone));
}
} // xmlDecl(String,String,String)
