|
| public void | cdata(char[] ch, int start, int length)Receive notification of cdata.
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).
if(isOutsideDocElem()
&& com.sun.org.apache.xml.internal.utils.XMLCharacterRecognizer.isWhiteSpace(ch, start, length))
return; // avoid DOM006 Hierarchy request error
String s = new String(ch, start, length);
CDATASection section =(CDATASection) m_currentNode.getLastChild();
section.appendData(s);
|
| public void | characters(char[] ch, int start, int length)Receive notification of character data.

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.

if(isOutsideDocElem()
&& com.sun.org.apache.xml.internal.utils.XMLCharacterRecognizer.isWhiteSpace(ch, start, length))
return; // avoid DOM006 Hierarchy request error
if (m_inCData)
{
cdata(ch, start, length);
return;
}
String s = new String(ch, start, length);
Node childNode;
childNode = m_currentNode != null ? m_currentNode.getLastChild(): null;
if( childNode != null && childNode.getNodeType() == Node.TEXT_NODE ){
((Text)childNode).appendData(s);
}
else{
Text text = m_doc.createTextNode(s);
append(text);
}
|
| public void | charactersRaw(char[] ch, int start, int length)If available, when the disable-output-escaping attribute is used,
output raw text without escaping. A PI will be inserted in front
of the node with the name "lotusxsl-next-is-raw" and a value of
"formatter-to-dom".
if(isOutsideDocElem()
&& com.sun.org.apache.xml.internal.utils.XMLCharacterRecognizer.isWhiteSpace(ch, start, length))
return; // avoid DOM006 Hierarchy request error
String s = new String(ch, start, length);
append(m_doc.createProcessingInstruction("xslt-next-is-raw",
"formatter-to-dom"));
append(m_doc.createTextNode(s));
|
| public void | comment(char[] ch, int start, int length)Report an XML comment anywhere in the document.
This callback will be used for comments inside or outside the
document element, including comments in the external DTD
subset (if read).
append(m_doc.createComment(new String(ch, start, length)));
|
| public void | endCDATA()Report the end of a CDATA section.
m_inCData = false;
|
| public void | endDTD()Report the end of DTD declarations.
// Do nothing for now.
|
| public void | endDocument()Receive notification of the end of a document.
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.
// No action for the moment.
|
| public void | endElement(java.lang.String ns, java.lang.String localName, java.lang.String name)Receive notification of the end of an element.
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.
m_elemStack.pop();
m_currentNode = m_elemStack.isEmpty() ? null : (Node)m_elemStack.peek();
|
| public void | endEntity(java.lang.String name)Report the end of an entity.
|
| public void | endPrefixMapping(java.lang.String prefix)End the scope of a prefix-URI mapping.
See startPrefixMapping for details. This event will
always occur after the corresponding endElement event,
but the order of endPrefixMapping events is not otherwise
guaranteed.
|
| public void | entityReference(java.lang.String name)Receive notivication of a entityReference.
append(m_doc.createEntityReference(name));
|
| public org.w3c.dom.Node | getCurrentNode()Get the node currently being processed.
return m_currentNode;
|
| public org.w3c.dom.Node | getNextSibling()Return the next sibling node.
return m_nextSibling;
|
| public org.w3c.dom.Node | getRootDocument()Get the root document or DocumentFragment of the DOM being created.
return (null != m_docFrag) ? (Node) m_docFrag : (Node) m_doc;
|
| public org.w3c.dom.Node | getRootNode()Get the root node of the DOM tree.
return m_root;
|
| public java.io.Writer | getWriter()Return null since there is no Writer for this class.
return null;
|
| public void | ignorableWhitespace(char[] ch, int start, int length)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.
if(isOutsideDocElem())
return; // avoid DOM006 Hierarchy request error
String s = new String(ch, start, length);
append(m_doc.createTextNode(s));
|
| private boolean | isOutsideDocElem()Tell if the current node is outside the document element.
return (null == m_docFrag) && m_elemStack.size() == 0 && (null == m_currentNode || m_currentNode.getNodeType() == Node.DOCUMENT_NODE);
|
| public void | processingInstruction(java.lang.String target, java.lang.String data)Receive notification of a processing instruction.
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.
append(m_doc.createProcessingInstruction(target, data));
|
| public void | setDocumentLocator(org.xml.sax.Locator locator)Receive an object for locating the origin of SAX document events.
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 ContentHandler
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.
// No action for the moment.
|
| public void | setIDAttribute(java.lang.String id, org.w3c.dom.Element elem)Set an ID string to node association in the ID table.
// Do nothing. This method is meant to be overiden.
|
| public void | setNextSibling(org.w3c.dom.Node nextSibling)Set the next sibling node, which is where the result nodes
should be inserted before.
m_nextSibling = nextSibling;
|
| public void | skippedEntity(java.lang.String name)Receive notification of a skipped entity.
The Parser will invoke this method once for each entity
skipped. Non-validating processors may skip entities if they
have not seen the declarations (because, for example, the
entity was declared in an external DTD subset). All processors
may skip external entities, depending on the values of the
http://xml.org/sax/features/external-general-entities and the
http://xml.org/sax/features/external-parameter-entities
properties.
|
| public void | startCDATA()Report the start of a CDATA section.
m_inCData = true;
append(m_doc.createCDATASection(""));
|
| public void | startDTD(java.lang.String name, java.lang.String publicId, java.lang.String systemId)Report the start of DTD declarations, if any.
Any declarations are assumed to be in the internal subset
unless otherwise indicated.
// Do nothing for now.
|
| public void | startDocument()Receive notification of the beginning of a document.
The SAX parser will invoke this method only once, before any
other methods in this interface or in DTDHandler (except for
setDocumentLocator).
// No action for the moment.
|
| public void | startElement(java.lang.String ns, java.lang.String localName, java.lang.String name, org.xml.sax.Attributes atts)Receive notification of the beginning of an element.
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.
Element elem;
// Note that the namespace-aware call must be used to correctly
// construct a Level 2 DOM, even for non-namespaced nodes.
if ((null == ns) || (ns.length() == 0))
elem = m_doc.createElementNS(null,name);
else
elem = m_doc.createElementNS(ns, name);
append(elem);
try
{
int nAtts = atts.getLength();
if (0 != nAtts)
{
for (int i = 0; i < nAtts; i++)
{
//System.out.println("type " + atts.getType(i) + " name " + atts.getLocalName(i) );
// First handle a possible ID attribute
if (atts.getType(i).equalsIgnoreCase("ID"))
setIDAttribute(atts.getValue(i), elem);
String attrNS = atts.getURI(i);
if("".equals(attrNS))
attrNS = null; // DOM represents no-namespace as null
// System.out.println("attrNS: "+attrNS+", localName: "+atts.getQName(i)
// +", qname: "+atts.getQName(i)+", value: "+atts.getValue(i));
// Crimson won't let us set an xmlns: attribute on the DOM.
String attrQName = atts.getQName(i);
// In SAX, xmlns[:] attributes have an empty namespace, while in DOM they
// should have the xmlns namespace
if (attrQName.startsWith("xmlns:") || attrQName.equals("xmlns")) {
attrNS = "http://www.w3.org/2000/xmlns/";
}
// ALWAYS use the DOM Level 2 call!
elem.setAttributeNS(attrNS,attrQName, atts.getValue(i));
}
}
// append(elem);
m_elemStack.push(elem);
m_currentNode = elem;
// append(elem);
}
catch(java.lang.Exception de)
{
// de.printStackTrace();
throw new org.xml.sax.SAXException(de);
}
|
| public void | startEntity(java.lang.String name)Report the beginning of an entity.
The start and end of the document entity are not reported.
The start and end of the external DTD subset are reported
using the pseudo-name "[dtd]". All other events must be
properly nested within start/end entity events.
// Almost certainly the wrong behavior...
// entityReference(name);
|
| public void | startPrefixMapping(java.lang.String prefix, java.lang.String uri)Begin the scope of a prefix-URI Namespace mapping.
The information from this event is not necessary for
normal Namespace processing: the SAX XML reader will
automatically replace prefixes for element and attribute
names when the http://xml.org/sax/features/namespaces
feature is true (the default).
There are cases, however, when applications need to
use prefixes in character data or in attribute values,
where they cannot safely be expanded automatically; the
start/endPrefixMapping event supplies the information
to the application to expand prefixes in those contexts
itself, if necessary.
Note that start/endPrefixMapping events are not
guaranteed to be properly nested relative to each-other:
all startPrefixMapping events will occur before the
corresponding startElement event, and all endPrefixMapping
events will occur after the corresponding endElement event,
but their order is not guaranteed.
/*
// Not sure if this is needed or wanted
// Also, it fails in the stree.
if((null != m_currentNode)
&& (m_currentNode.getNodeType() == Node.ELEMENT_NODE))
{
String qname;
if(((null != prefix) && (prefix.length() == 0))
|| (null == prefix))
qname = "xmlns";
else
qname = "xmlns:"+prefix;
Element elem = (Element)m_currentNode;
String val = elem.getAttribute(qname); // Obsolete, should be DOM2...?
if(val == null)
{
elem.setAttributeNS("http://www.w3.org/XML/1998/namespace",
qname, uri);
}
}
