Interface LSParser

public static final short ACTION_APPEND_AS_CHILDREN

Append the result of the parse operation as children of the context node. For this action to work, the context node must be an Element or a DocumentFragment.

Field Value:

1

public static final short ACTION_INSERT_AFTER

Insert the result of the parse operation as the immediately following sibling of the context node. For this action to work the context node's parent must be an Element or a DocumentFragment.

Field Value:

4

public static final short ACTION_INSERT_BEFORE

Insert the result of the parse operation as the immediately preceding sibling of the context node. For this action to work the context node's parent must be an Element or a DocumentFragment.

Field Value:

3

public static final short ACTION_REPLACE

Replace the context node with the result of the parse operation. For this action to work, the context node must have a parent, and the parent must be an Element or a DocumentFragment.

Field Value:

5

public static final short ACTION_REPLACE_CHILDREN

Replace all the children of the context node with the result of the parse operation. For this action to work, the context node must be an Element, a Document, or a DocumentFragment.

Field Value:

2

public void abort()

Abort the loading of the document that is currently being loaded by the LSParser. If the LSParser is currently not busy, a call to this method does nothing.

public boolean getAsync()

true if the LSParser is asynchronous, false if it is synchronous.

public boolean getBusy()

true if the LSParser is currently busy loading a document, otherwise false.

public DOMConfiguration getDomConfig()

The 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.
In addition to the parameters recognized in on the DOMConfiguration interface defined in [DOM Level 3 Core] , the DOMConfiguration objects for LSParser add or modify the following parameters:

public LSParserFilter getFilter()

When a filter is provided, the implementation will call out to the filter as it is constructing the DOM tree structure. The filter can choose to remove elements from the document being constructed, or to terminate the parsing early.
The filter is invoked after the operations requested by the DOMConfiguration parameters have been applied. For example, if " validate" is set to true, the validation is done before invoking the filter.

public Document parse(LSInput input)
            throws DOMException,
                   LSException

Parse an XML document from a resource identified by a LSInput.

Parameters:

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

Returns:

If the 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.

Throws:

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.

public Document parseURI(String uri)
            throws DOMException,
                   LSException

Parse an XML document from a location identified by a URI reference [IETF RFC 2396]. If the URI contains a fragment identifier (see section 4.1 in [IETF RFC 2396]), the behavior is not defined by this specification, future versions of this specification may define the behavior.

Parameters:

uri - The location of the XML document to be read.

Returns:

If the 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.

Throws:

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.

public Node parseWithContext(LSInput input,
                             Node contextArg,
                             short action)
            throws DOMException,
                   LSException

Parse an XML fragment from a resource identified by a 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.
As the new data is inserted into the document, at least one mutation event is fired per new immediate child or sibling of the context node.
If the context node is a 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().
This method is always synchronous, even if the LSParser is asynchronous (LSParser.async is true).
If an error occurs while parsing, the caller is notified through the ErrorHandler instance associated with the " error-handler" parameter of the DOMConfiguration.
When calling 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.

Parameters:

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.

Returns:

Return the node that is the result of the parse operation. If the result is more than one top-level node, the first one is returned.

Throws:

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] ).
NOT_SUPPORTED_ERR: Raised if the 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.
NO_MODIFICATION_ALLOWED_ERR: Raised if the context node is a read only node and the content is being appended to its child list, or if the parent node of the context node is read only node and the content is being inserted in its child list.
INVALID_STATE_ERR: Raised if the 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.

public void setFilter(LSParserFilter filter)

When a filter is provided, the implementation will call out to the filter as it is constructing the DOM tree structure. The filter can choose to remove elements from the document being constructed, or to terminate the parsing early.
The filter is invoked after the operations requested by the DOMConfiguration parameters have been applied. For example, if " validate" is set to true, the validation is done before invoking the filter.
