      public XML11DocumentScannerImpl()
      Default constructor.

  • Method Details

    • scanContent

      protected int scanContent() throws IOException, org.apache.xerces.xni.XNIException
      Scans element content.
      Overrides:
      scanContent in class XMLDocumentFragmentScannerImpl
      Returns:
      Returns the next character on the stream.
      Throws:
      IOException
      org.apache.xerces.xni.XNIException

    • scanAttributeValue

      protected boolean scanAttributeValue(org.apache.xerces.xni.XMLString value, org.apache.xerces.xni.XMLString nonNormalizedValue, String atName, boolean checkEntities, String eleName) throws IOException, org.apache.xerces.xni.XNIException
      Scans an attribute value and normalizes whitespace converting all whitespace characters to space characters. [10] AttValue ::= '"' ([^invalid input: '<'invalid input: '&'"] | Reference)* '"' | "'" ([^invalid input: '<'invalid input: '&''] | Reference)* "'"
      Overrides:
      scanAttributeValue in class XMLScanner
      Parameters:
      value - The XMLString to fill in with the value.
      nonNormalizedValue - The XMLString to fill in with the non-normalized value.
      atName - The name of the attribute being parsed (for error msgs).
      checkEntities - true if undeclared entities should be reported as VC violation, false if undeclared entities should be reported as WFC violation.
      eleName - The name of element to which this attribute belongs.
      Returns:
      true if the non-normalized and normalized value are the same Note: This method uses fStringBuffer2, anything in it at the time of calling is lost.
      Throws:
      IOException
      org.apache.xerces.xni.XNIException

    • 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
