Constructor Detail

SpaceStrippedDocument

public SpaceStrippedDocument(TreeInfo doc,
                     SpaceStrippingRule strippingRule)

Create a space-stripped view of a document

Parameters:

doc - the underlying document

strippingRule - an object that contains the rules defining which whitespace text nodes are to be absent from the view

Method Detail

wrap

public SpaceStrippedNode wrap(NodeInfo node)

Create a wrapped node within this document

isTyped

public boolean isTyped()

Ask whether the document contains any nodes whose type annotation is anything other than UNTYPED

Specified by:

isTyped in interface TreeInfo

Overrides:

isTyped in class GenericTreeInfo

Returns:

true if the document contains elements whose type is other than UNTYPED

getStrippingRule

public SpaceStrippingRule getStrippingRule()

Get the document's strippingRule

selectID

public NodeInfo selectID(String id,
                boolean getParent)

Get the element with a given ID, if any

Specified by:

selectID in interface TreeInfo

Overrides:

selectID in class GenericTreeInfo

Parameters:

id - the required ID value

getParent - true if we want the parent of an element with the ID value

Returns:

the element with the given ID value, or null if there is none.

getUnparsedEntityNames

public Iterator<String> getUnparsedEntityNames()

Get the list of unparsed entities defined in this document

Specified by:

getUnparsedEntityNames in interface TreeInfo

Overrides:

getUnparsedEntityNames in class GenericTreeInfo

Returns:

an Iterator, whose items are of type String, containing the names of all unparsed entities defined in this document. If there are no unparsed entities or if the information is not available then an empty iterator is returned

getUnparsedEntity

public String[] getUnparsedEntity(String name)

Get the unparsed entity with a given name

Specified by:

getUnparsedEntity in interface TreeInfo

Overrides:

getUnparsedEntity in class GenericTreeInfo

Parameters:

name - the name of the entity

Returns:

if the entity exists, return an array of two Strings, the first holding the system ID of the entity (as an absolute URI if possible), the second holding the public ID if there is one, or null if not. If the entity does not exist, the method returns null. Applications should be written on the assumption that this array may be extended in the future to provide additional information.

containsPreserveSpace

public boolean containsPreserveSpace()

Ask whether the stripped document contains any xml:space="preserve" attributes.

Returns:

true if any element in the document has an xml:space attribute with the value "preserve"

containsAssertions

public boolean containsAssertions()

Ask whether the stripped document contain any nodes annotated with types that carry assertions

Returns:

true if any element in the document has a type that has an assertion
