Constructor Detail

DOMParserImpl

public DOMParserImpl(java.lang.String configuration,
             java.lang.String schemaType)

Constructs a DOM Builder using the standard parser configuration.

DOMParserImpl

public DOMParserImpl(org.apache.xerces.xni.parser.XMLParserConfiguration config)

Constructs a DOM Builder using the specified parser configuration.

DOMParserImpl

public DOMParserImpl(SymbolTable symbolTable)

Constructs a DOM Builder using the specified symbol table.

DOMParserImpl

public DOMParserImpl(SymbolTable symbolTable,
             org.apache.xerces.xni.grammars.XMLGrammarPool grammarPool)

Method Detail

reset

public void reset()

Resets the parser state.

Overrides:

reset in class AbstractDOMParser

Throws:

org.xml.sax.SAXException - Thrown on initialization error.

getDomConfig

public org.w3c.dom.DOMConfiguration getDomConfig()

Specified by:

getDomConfig in interface org.w3c.dom.ls.LSParser

getFilter

public org.w3c.dom.ls.LSParserFilter getFilter()

When the application provides a filter, the parser will call out to the filter at the completion of the construction of each Element node. The filter implementation can choose to remove the element from the document being constructed (unless the element is the document element) or to terminate the parse early. If the document is being validated when it's loaded the validation happens before the filter is called.

Specified by:

getFilter in interface org.w3c.dom.ls.LSParser

setFilter

public void setFilter(org.w3c.dom.ls.LSParserFilter filter)

When the application provides a filter, the parser will call out to the filter at the completion of the construction of each Element node. The filter implementation can choose to remove the element from the document being constructed (unless the element is the document element) or to terminate the parse early. If the document is being validated when it's loaded the validation happens before the filter is called.

Specified by:

setFilter in interface org.w3c.dom.ls.LSParser

setParameter

public void setParameter(java.lang.String name,
                java.lang.Object value)

Set parameters and properties

Specified by:

setParameter in interface org.w3c.dom.DOMConfiguration

Throws:

org.w3c.dom.DOMException

getParameter

public java.lang.Object getParameter(java.lang.String name)
                              throws org.w3c.dom.DOMException

Look up the value of a feature or a property.

Specified by:

getParameter in interface org.w3c.dom.DOMConfiguration

Throws:

org.w3c.dom.DOMException

canSetParameter

public boolean canSetParameter(java.lang.String name,
                      java.lang.Object value)

Specified by:

canSetParameter in interface org.w3c.dom.DOMConfiguration

getParameterNames

public org.w3c.dom.DOMStringList getParameterNames()

DOM Level 3 CR - Experimental. The list of the parameters supported by this DOMConfiguration object and for which at least one value can be set by the application. Note that this list can also contain parameter names defined outside this specification.

Specified by:

getParameterNames in interface org.w3c.dom.DOMConfiguration

parseURI

public org.w3c.dom.Document parseURI(java.lang.String uri)
                              throws org.w3c.dom.ls.LSException

Parse an XML document from a location identified by an URI reference. If the URI contains a fragment identifier (see section 4.1 in ), the behavior is not defined by this specification.

Specified by:

parseURI in interface org.w3c.dom.ls.LSParser

Specified by:

parse in interface org.w3c.dom.ls.LSParser

Throws:

org.w3c.dom.ls.LSException

parseWithContext

public org.w3c.dom.Node parseWithContext(org.w3c.dom.ls.LSInput is,
                                org.w3c.dom.Node cnode,
                                short action)
                                  throws org.w3c.dom.DOMException,
                                         org.w3c.dom.ls.LSException

Parse an XML document or fragment from a resource identified by an LSInput and insert the content into an existing document at the position epcified with the contextNode and action arguments. When parsing the input stream the context node is used for resolving unbound namespace prefixes.

Specified by:

parseWithContext in interface org.w3c.dom.ls.LSParser

Parameters:

is - The LSInput from which the source document is to be read.

cnode - The Node that is used as the context for the data that is being parsed.
