Class XML11DTDScannerImpl

Implemented Interfaces:
org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLDTDScanner, XMLEntityHandler

public class XML11DTDScannerImpl
extends XMLDTDScannerImpl

This class is responsible for scanning the declarations found in the internal and external subsets of a DTD in an XML document. The scanner acts as the sources for the DTD information which is communicated to the DTD handlers.

This component requires the following features and properties from the component manager that uses it:

Checks whether this string would be unchanged by normalization.
Overrides:
isUnchangedByNormalization in interface XMLScanner
Returns:
-1 if the value would be unchanged by normalization, otherwise the index of the first whitespace character which would be transformed.

[12] PubidLiteral ::= '"' PubidChar* '"' | "'" (PubidChar - "'")* "'" [13] PubidChar::= #x20 | #xD | #xA | [a-zA-Z0-9] | [-'()+,./:=?;!*#@$_%] The returned string is normalized according to the following rule, from http://www.w3.org/TR/REC-xml#dt-pubid: Before a match is attempted, all strings of white space in the public identifier must be normalized to single space characters (#x20), and leading and trailing white space must be removed.
Overrides:
scanPubidLiteral in interface XMLScanner
Parameters:
literal - The string to fill in with the public ID literal.
Returns:
True on success. Note: This method uses fStringBuffer, anything in it at the time of calling is lost.
