DOMConfiguration getDomConfig()
DOMConfiguration
object used when parsing an input
source. This DOMConfiguration
is specific to the parse
operation. No parameter values from this DOMConfiguration
object are passed automatically to the DOMConfiguration
object on the Document
that is created, or used, by the
parse operation. The DOM application is responsible for passing any
needed parameter values from this DOMConfiguration
object to the DOMConfiguration
object referenced by the
Document
object.
DOMConfiguration
objects for LSParser
add or modify the following parameters:
"charset-overrides-xml-encoding"
true
LSInput
overrides
any encoding from the protocol. false
"disallow-doctype"
true
false
"ignore-unknown-character-denormalizations"
true
false
"infoset"
DOMConfiguration
for a description of
this parameter. Unlike in [DOM Level 3 Core]
, this parameter will default to true
for
LSParser
. "namespaces"
true
false
"resource-resolver"
LSResourceResolver
object, or null. If
the value of this parameter is not null when an external resource
(such as an external XML entity or an XML schema location) is
encountered, the implementation will request that the
LSResourceResolver
referenced in this parameter resolves
the resource. "supported-media-types-only"
true
false
"validate"
DOMConfiguration
for a description of this parameter.
Unlike in [DOM Level 3 Core]
, the processing of the internal subset is always accomplished, even
if this parameter is set to false
. "validate-if-schema"
DOMConfiguration
for a description of this parameter.
Unlike in [DOM Level 3 Core]
, the processing of the internal subset is always accomplished, even
if this parameter is set to false
. "well-formed"
DOMConfiguration
for a description of this parameter.
Unlike in [DOM Level 3 Core]
, this parameter cannot be set to false
.
LSParserFilter getFilter()
DOMConfiguration
parameters have been applied. For
example, if "
validate" is set to true
, the validation is done before invoking the
filter.
void setFilter(LSParserFilter filter)
DOMConfiguration
parameters have been applied. For
example, if "
validate" is set to true
, the validation is done before invoking the
filter.
boolean getAsync()
true
if the LSParser
is asynchronous,
false
if it is synchronous.
boolean getBusy()
true
if the LSParser
is currently busy
loading a document, otherwise false
.
Document parse(LSInput input) throws DOMException, LSException
LSInput
.
input
- The LSInput
from which the source of the
document is to be read.
LSParser
is a synchronous
LSParser
, the newly created and populated
Document
is returned. If the LSParser
is
asynchronous, null
is returned since the document
object may not yet be constructed when this method returns.
DOMException
- INVALID_STATE_ERR: Raised if the LSParser
's
LSParser.busy
attribute is true
.
LSException
- PARSE_ERR: Raised if the LSParser
was unable to load
the XML document. DOM applications should attach a
DOMErrorHandler
using the parameter "
error-handler" if they wish to get details on the error.Document parseURI(String uri) throws DOMException, LSException
uri
- The location of the XML document to be read.
LSParser
is a synchronous
LSParser
, the newly created and populated
Document
is returned, or null
if an error
occured. If the LSParser
is asynchronous,
null
is returned since the document object may not yet
be constructed when this method returns.
DOMException
- INVALID_STATE_ERR: Raised if the LSParser.busy
attribute is true
.
LSException
- PARSE_ERR: Raised if the LSParser
was unable to load
the XML document. DOM applications should attach a
DOMErrorHandler
using the parameter "
error-handler" if they wish to get details on the error.Node parseWithContext(LSInput input, Node contextArg, short action) throws DOMException, LSException
LSInput
and insert the content into an existing document
at the position specified with the context
and
action
arguments. When parsing the input stream, the
context node (or its parent, depending on where the result will be
inserted) is used for resolving unbound namespace prefixes. The
context node's ownerDocument
node (or the node itself if
the node of type DOCUMENT_NODE
) is used to resolve
default attributes and entity references.
Document
node and the action
is ACTION_REPLACE_CHILDREN
, then the document that is
passed as the context node will be changed such that its
xmlEncoding
, documentURI
,
xmlVersion
, inputEncoding
,
xmlStandalone
, and all other such attributes are set to
what they would be set to if the input source was parsed using
LSParser.parse()
.
LSParser
is asynchronous (LSParser.async
is
true
).
ErrorHandler
instance associated with the "
error-handler" parameter of the DOMConfiguration
.
parseWithContext
, the values of the
following configuration parameters will be ignored and their default
values will always be used instead: "
validate", "
validate-if-schema", and "
element-content-whitespace". Other parameters will be treated normally, and the parser is expected
to call the LSParserFilter
just as if a whole document
was parsed.
input
- The LSInput
from which the source document
is to be read. The source document must be an XML fragment, i.e.
anything except a complete XML document (except in the case where
the context node of type DOCUMENT_NODE
, and the action
is ACTION_REPLACE_CHILDREN
), a DOCTYPE (internal
subset), entity declaration(s), notation declaration(s), or XML or
text declaration(s).contextArg
- The node that is used as the context for the data
that is being parsed. This node must be a Document
node, a DocumentFragment
node, or a node of a type
that is allowed as a child of an Element
node, e.g. it
cannot be an Attribute
node.action
- This parameter describes which action should be taken
between the new set of nodes being inserted and the existing
children of the context node. The set of possible actions is
defined in ACTION_TYPES
above.
DOMException
- HIERARCHY_REQUEST_ERR: Raised if the content cannot replace, be
inserted before, after, or as a child of the context node (see also
Node.insertBefore
or Node.replaceChild
in [DOM Level 3 Core]
).
LSParser
doesn't
support this method, or if the context node is of type
Document
and the DOM implementation doesn't support
the replacement of the DocumentType
child or
Element
child.
LSParser.busy
attribute is true
.
LSException
- PARSE_ERR: Raised if the LSParser
was unable to load
the XML fragment. DOM applications should attach a
DOMErrorHandler
using the parameter "
error-handler" if they wish to get details on the error.void abort()
LSParser
. If the LSParser
is currently
not busy, a call to this method does nothing.
