- See Also:
endDTD()
-
endDTD
void endDTD() throws org.xml.sax.SAXException
Receive notification of the end of a DTD. The parser will invoke this method only once.- Throws:

- See Also:
startDTD(InputEntity)
-
comment
void comment(java.lang.String text) throws org.xml.sax.SAXException
Receive notification that a comment has been read.Note that processing instructions are the mechanism designed to hold information for consumption by applications, not comments. XML systems may rely on applications being able to access information found in processing instructions; this is not true of comments, which are typically discarded.
- Parameters:
text
- the text within the comment delimiters.- Throws:
org.xml.sax.SAXException
-
characters
void characters(char[] ch, int start, int length) throws org.xml.sax.SAXException
Receive notification of character data.The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.
The application must not attempt to read from the array outside of the specified range.
Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).
- Parameters:
ch
- The characters from the DTD.start
- The start position in the array.length
- The number of characters to read from the array.- Throws:
org.xml.sax.SAXException
- See Also:
ignorableWhitespace(char[], int, int)
-
ignorableWhitespace
void ignorableWhitespace(char[] ch, int start, int length) throws org.xml.sax.SAXException
Receive notification of ignorable whitespace in element content.Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.
SAX parsers may return all contiguous whitespace in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.
The application must not attempt to read from the array outside of the specified range.
- Parameters:
ch
- The characters from the DTD.start
- The start position in the array.length
- The number of characters to read from the array.- Throws:
org.xml.sax.SAXException
- See Also:
characters(char[], int, int)
-
startCDATA
void startCDATA() throws org.xml.sax.SAXException
Receive notification that a CDATA section is beginning. Data in a CDATA section is is reported through the appropriate event, either characters() or ignorableWhitespace.- Throws:

-
endCDATA
void endCDATA() throws org.xml.sax.SAXException
Receive notification that the CDATA section finished.- Throws:

void startContentModel(java.lang.String elementName, short contentModelType) throws org.xml.sax.SAXException
receives notification that parsing of content model is beginning.- Parameters:
elementName
- name of the element whose content model is going to be defined.contentModelType
-CONTENT_MODEL_EMPTY
this element has EMPTY content model. This notification will be immediately followed by the corresponding endContentModel.CONTENT_MODEL_ANY
this element has ANY content model. This notification will be immediately followed by the corresponding endContentModel.CONTENT_MODEL_MIXED
this element has mixed content model. #PCDATA will not be reported. each child element will be reported by mixedElement method.CONTENT_MODEL_CHILDREN
this elemen has child content model. The actual content model will be reported by childElement, startModelGroup, endModelGroup, and connector methods. Possible call sequences are: START := MODEL_GROUP MODEL_GROUP := startModelGroup TOKEN (connector TOKEN)* endModelGroup TOKEN := childElement | MODEL_GROUP- Throws:
org.xml.sax.SAXException
-
endContentModel
void endContentModel(java.lang.String elementName, short contentModelType) throws org.xml.sax.SAXException
receives notification that parsing of content model is finished.- Throws:

attributeDecl
void attributeDecl(java.lang.String elementName, java.lang.String attributeName, java.lang.String attributeType, java.lang.String[] enumeration, short attributeUse, java.lang.String defaultValue) throws org.xml.sax.SAXException
For each entry in an ATTLIST declaration, this event will be fired.DTD allows the same attributes to be declared more than once, and in that case the first one wins. I think this method will be only fired for the first one, but I need to check.
- Throws:
org.xml.sax.SAXException
-
childElement
void childElement(java.lang.String elementName, short occurence) throws org.xml.sax.SAXException
- Throws:
org.xml.sax.SAXException
-
mixedElement
void mixedElement(java.lang.String elementName) throws org.xml.sax.SAXException
receives notification of child element of mixed content model. this method is called for each child element.- Throws:
org.xml.sax.SAXException
- See Also:
startContentModel(String, short)
-

void startModelGroup() throws org.xml.sax.SAXException
- Throws:
org.xml.sax.SAXException
-
endModelGroup
void endModelGroup(short occurence) throws org.xml.sax.SAXException
- Throws:
org.xml.sax.SAXException
-
connector
void connector(short connectorType) throws org.xml.sax.SAXException
Connectors in one model group is guaranteed to be the same.IOW, you'll never see an event sequence like (a|b,c)
