public class XMLFragmentReader
extends DOMReader

Internal:

Purpose: An implementation of XMLReader for parsing XMLFragment Nodes into SAX events.

Responsibilities:

• Walk the XMLFragment node's DOM tree and report sax events to the provided content handler
• Report lexical events to the lexical handler if it's provided

                  java.lang.String uri,
                  java.lang.String name)
           throws org.xml.sax.SAXException

Overrides:

parse in class DOMReader

Throws:

org.xml.sax.SAXException

reportElementEvents

protected void reportElementEvents(org.w3c.dom.Element elem)
                            throws org.xml.sax.SAXException

Overrides:

reportElementEvents in class DOMReader

Throws:

org.xml.sax.SAXException

endDocument

protected void endDocument()
                    throws org.xml.sax.SAXException

Trigger an endDocument event on the contenthandler.

Overrides:

endDocument in class DOMReader

Throws:

org.xml.sax.SAXException

startDocument

protected void startDocument()
                      throws org.xml.sax.SAXException

Trigger a startDocument event on the contenthandler.

Overrides:

startDocument in class DOMReader

Throws:

org.xml.sax.SAXException

handleNewNamespaceDeclaration

protected void handleNewNamespaceDeclaration(org.w3c.dom.Element elem,
                                             java.lang.String prefix,
                                             java.lang.String namespaceURI)

Overrides:

handleNewNamespaceDeclaration in class DOMReader

handlePrefixedAttribute

protected void handlePrefixedAttribute(org.w3c.dom.Element elem)
                                throws org.xml.sax.SAXException

Handle prefixed attribute - may need to declare the namespace URI locally.

Overrides:

handlePrefixedAttribute in class DOMReader

Throws:

org.xml.sax.SAXException

endPrefixMappings

protected void endPrefixMappings(org.w3c.dom.Element elem)
                          throws org.xml.sax.SAXException

If there is a temporary namespace resolver for a given element, each entry contains a prefix that requires an endPrefixMapping event to be triggered

Overrides:

endPrefixMappings in class DOMReader

Throws:

org.xml.sax.SAXException

getTempResolver

protected NamespaceResolver getTempResolver(org.w3c.dom.Element elem)

Returns the namespace resolver in the map of temporary namespace resolvers for a given element

Parameters:

elem -

Returns:

the namespace resolver in the map for elem, or a new resolver if none exists

cleanupNamespaceResolvers

protected void cleanupNamespaceResolvers(org.w3c.dom.Element elem)

Remove any temporary namespace resolvers created while processing a given element.

Parameters:

elem -

resolveNamespacePrefix

protected java.lang.String resolveNamespacePrefix(java.lang.String prefix)

Convenience method that iterates over each namespace resolver in the resolver list until it locates a uri for 'prefix' or the final resolver is reached w/o success.

Parameters:

prefix -

Returns:

true if a URI exists in one of the resolvers in the list, false otherwise

processParentNamespaces

protected void processParentNamespaces(org.w3c.dom.Element element)
                                throws org.xml.sax.SAXException

Process namespace declarations on parent elements if not the root. For each parent node from current to root place puch each onto a stack, then pop each off, calling startPrefixMapping for each XMLNS attribute. Using a stack ensures that the parent nodes are processed top down.

Overrides:

processParentNamespaces in class DOMReader

Parameters:

element -

Throws:

org.xml.sax.SAXException

handleXsiTypeAttribute

protected void handleXsiTypeAttribute(org.w3c.dom.Attr attr)

Overrides:

handleXsiTypeAttribute in class DOMReader

Throws:

org.xml.sax.SAXException
