java.lang.Object | +--weblogic.apache.xalan.xslt.StylesheetHandler
Initializes and processes a stylesheet via SAX events. If you need to alter the code in here, it is not for the faint-of-heart, due to the state tracking that has to be done due to the SAX event model.
This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

public void setDocumentLocator(org.xml.sax.Locator locator)
SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the DocumentHandler interface.
The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application's business rules). The information returned by the locator is probably not sufficient for use with a search engine.
Note that the locator will return correct information only during the invocation of the events in this interface. The application should not attempt to use it at any other time.
locator - An object that can return the location of
any SAX document event.Locator
public void startDocument()
throws org.xml.sax.SAXException
The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).
public void endDocument()
throws org.xml.sax.SAXException
The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.
public void startElement(java.lang.String name,
org.xml.sax.AttributeList atts)
throws org.xml.sax.SAXException
The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding endElement() event for every startElement() event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement() event.
If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted.
name - The element type name.atts - The attributes attached to the element, if any.endElement(java.lang.String),
AttributeList
public org.xml.sax.InputSource resolveEntity(java.lang.String publicId,
java.lang.String systemId)
throws org.xml.sax.SAXException,
java.io.IOException
public void endElement(java.lang.String name)
throws org.xml.sax.SAXException
The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement() event for every endElement() event (even when the element is empty).
If the element name has a namespace prefix, the prefix will still be attached to the name.
name - The element type namepublic static boolean isSpace(char ch)
S for details.
ch - Character to check as XML whitespace.
public boolean isWhiteSpace(char[] ch,
int start,
int length)
string - String to be trimmed.
public void characters(char[] ch,
int start,
int length)
throws org.xml.sax.SAXException
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).
ch - The characters from the XML document.start - The start position in the array.length - The number of characters to read from the array.ignorableWhitespace(char[], int, int),
Locator
public void cdata(char[] ch,

throws org.xml.sax.SAXException
The Parser will call this method to report each chunk of character data.

Locator
public void ignorableWhitespace(char[] ch,
int start,
int length)
throws org.xml.sax.SAXException
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.
ch - The characters from the XML document.start - The start position in the array.length - The number of characters to read from the array.characters(char[], int, int)
public void processingInstruction(java.lang.String target,
java.lang.String data)
throws org.xml.sax.SAXException
The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.
A SAX parser should never report an XML declaration (XML 1.0, section 2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.
target - The processing instruction target.data - The processing instruction data, or null if
none was supplied.
public void comment(java.lang.String data)
throws org.xml.sax.SAXException
data - The comment data.
public void entityReference(java.lang.String name)
throws org.xml.sax.SAXException
