Constructor Detail

DocumentWrapper

public DocumentWrapper(Node root, String baseURI, Configuration config)
Create a Saxon wrapper for a XOM root node

Parameters: root The XOM root node baseURI The base URI for all the nodes in the tree config The configuration which defines the name pool used for all names in this tree

Method Detail

getConfiguration

public Configuration getConfiguration()
Get the configuration previously set using setConfiguration

getDocumentNumber

public int getDocumentNumber()
Get the unique document number for this document (the number is unique for all documents within a NamePool)

Returns: the unique number identifying this document within the name pool

getNamePool

public NamePool getNamePool()
Get the name pool used for the names in this document

Returns: the name pool in which all the names used in this document are registered

getUnparsedEntity

public String[] getUnparsedEntity(String name)
Get the unparsed entity with a given name

Parameters: name the name of the entity

Returns: null: XOM does not provide access to unparsed entities if the entity exists, return an array of two Strings, the first holding the system ID of the entity, the second holding the public ID if there is one, or null if not. If the entity does not exist, return null.

selectID

public NodeInfo selectID(String id)
Get the element with a given ID, if any

Parameters: id the required ID value

Returns: the element with the given ID, or null if there is no such ID present (or if the parser has not notified attributes as being of type ID).

setConfiguration

public void setConfiguration(Configuration config)
Set the configuration, which defines the name pool used for all names in this document. This is always called after a new document has been created. The implementation must register the name pool with the document, so that it can be retrieved using getNamePool(). It must also call NamePool.allocateDocumentNumber(), and return the relevant document number when getDocumentNumber() is subsequently called.

Parameters: config The configuration to be used

wrap

public NodeInfo wrap(Node node)
Wrap a node in the XOM document.

Parameters: node The node to be wrapped. This must be a node in the same document (the system does not check for this).

Returns: the wrapping NodeInfo object
