      • scanPubidLiteral

        protected boolean scanPubidLiteral​(org.apache.xerces.xni.XMLString literal)
                            throws java.io.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:
        java.io.IOException
        org.apache.xerces.xni.XNIException
