Class XML11DTDScannerImpl

java.lang.Object
org.apache.xerces.impl.XMLScanner
org.apache.xerces.impl.XMLDTDScannerImpl
org.apache.xerces.impl.XML11DTDScannerImpl
All Implemented Interfaces:
XMLEntityHandler, org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLDTDContentModelSource, org.apache.xerces.xni.parser.XMLDTDScanner, org.apache.xerces.xni.parser.XMLDTDSource
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:

  • http://xml.org/sax/features/validation
  • http://apache.org/xml/features/scanner/notify-char-refs
  • http://apache.org/xml/properties/internal/symbol-table
  • http://apache.org/xml/properties/internal/error-reporter
  • http://apache.org/xml/properties/internal/entity-manager

  • Method Details

    • scanPubidLiteral

      protected boolean scanPubidLiteral(org.apache.xerces.xni.XMLString literal) throws IOException, org.apache.xerces.xni.XNIException
      Scans public ID literal. [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 class 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.
      Throws:
      IOException
      org.apache.xerces.xni.XNIException

    • normalizeWhitespace
