Interface XMLDTDScanner
- All Superinterfaces:
XMLDTDContentModelSource
,XMLDTDSource
This interface defines a generic DTD scanner. This interface
allows a scanner to be used interchangably in existing parser
configurations.
If the parser configuration uses a DTD scanner that implements this interface, components should be able to query the scanner instance from the component manager using the following property identifier:
"http://apache.org/xml/properties/internal/dtd-scanner"

scanDTDInternalSubset
boolean scanDTDInternalSubset(boolean complete, boolean standalone, boolean hasExternalSubset) throws IOException, XNIException Scans the internal subset of the document.- Parameters:
complete
- True if the scanner should scan the document completely, pushing all events to the registered document handler. A value of false indicates that that the scanner should only scan the next portion of the document and return. A scanner instance is permitted to completely scan a document if it does not support this "pull" scanning model.standalone
- True if the document was specified as standalone. This value is important for verifying certain well-formedness constraints.hasExternalSubset
- True if the document has an external DTD. This allows the scanner to properly notify the handler of the end of the DTD in the absence of an external subset.- Returns:
- True if there is more to scan, false otherwise.
- Throws:
IOException
XNIException
