If I have a document that looks like this...
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE DIALOG SYSTEM "VoxML.dtd" [
<!ENTITY ServletURL 'http://127.0.0.1:8080'>
]>
<DIALOG BARGEIN="N">
<STEP NAME="init" PARENT="init">
<PROMPT>Greeting for &ServletURL;</PROMPT>
<INPUT TYPE="HIDDEN" NAME="Action"
VALUE="launchEmailApplication"/>
<INPUT TYPE="NONE"
NEXT="&ServletURL;/servlet/VoxSurf.Architecture.VoxML.VxsVoxMLApplicationServlet"/>
</STEP>
</DIALOG>
How do I tell the internal subset apart from the external
subset? Normally I'd do...
public void doctypeDecl(String rootElement, String publicId, String
systemId, Augmentations augs) throws XNIException {
if (publicId == null && systemId == null) {
fProcessingState = PROCESSING_INTERNAL_SUBSET;
fInternalSubset = new StringBuffer();
} else {
fProcessingState = PROCESSING_EXTERNAL_SUBSET;
}
}
However, in this case, the System Id is not null, so I default to the
extenal subset processing state. In the other DTD event methods, I
check which state I'm in and only append to the internal subset
buffer when I'm in the internal subset processing state. If I build
a document from this, the output excludes the <!ENTITY> declaration
inside what is, really, the internal subset. Thus, parsing of the
resulting document fails because the document references
"&ServletURL;", but the <!ENTITY> declaration does not exist.
So, is there some unique condition I can look for while using the XNI
parser to determine if I am parsing the internal subset when the
external and internal subsets are combined?
