Method Detail

initialise

public void initialise(int nameCode,
              AttributeCollection atts,
              NodeInfo parent,
              String baseURI,
              int lineNumber,
              int sequenceNumber)

Initialise a new ElementWithAttributes with an element name and attribute list

Overrides:

initialise in class ElementImpl

Parameters:

name - The element name, with namespaces resolved

atts - The attribute list, after namespace processing

parent - The parent node

setNamespaceDeclarations

public void setNamespaceDeclarations(int[] namespaces,
                            int namespacesUsed)

Set the namespace declarations for the element

getURICodeForPrefix

public short getURICodeForPrefix(String prefix)
                          throws NamespaceException

Search the NamespaceList for a given prefix, returning the corresponding URI.

Overrides:

getURICodeForPrefix in class ElementImpl

Parameters:

prefix - The prefix to be matched. To find the default namespace, supply ""

Returns:

The URI code corresponding to this namespace. If it is an unnamed default namespace, return Namespace.NULL_CODE.

Throws:

NamespaceException - if the prefix has not been declared on this NamespaceList.

getPrefixForURI

public String getPrefixForURI(String uri)

Search the NamespaceList for a given URI, returning the corresponding prefix.

Overrides:

getPrefixForURI in class ElementImpl

Parameters:

uri - The URI to be matched.

Returns:

The prefix corresponding to this URI. If not found, return null. If there is more than one prefix matching the URI, the first one found is returned. If the URI matches the default namespace, return an empty string.

addNamespaceNodes

public void addNamespaceNodes(ElementImpl owner,
                     Vector list,
                     boolean addXML)

Make the set of all namespace nodes associated with this element.

Overrides:

addNamespaceNodes in class ElementImpl

Parameters:

owner - The element owning these namespace nodes.

list - a Vector containing NamespaceImpl objects representing the namespaces in scope for this element; the method appends nodes to this Vector, which should initially be empty. Note that the returned list will never contain the XML namespace (to get this, the NamespaceEnumeration class adds it itself). The list WILL include an entry for the undeclaration xmlns=""; again it is the job of NamespaceEnumeration to ignore this, since it doesn't represent a true namespace node.

addXML - Add a namespace node for the XML namespace

outputNamespaceNodes

public void outputNamespaceNodes(Outputter out,
                        boolean includeAncestors)

Specified by:

outputNamespaceNodes in interface NodeInfo

Overrides:

outputNamespaceNodes in class ElementImpl

Parameters:

includeAncestors - True if namespaces declared on ancestor elements must be output; false if it is known that these are already on the result tree

Throws:

TransformerException

getNamespaceCodes

protected int[] getNamespaceCodes()

Get the list of in-scope namespaces for this element as an array of namespace codes. (Used by LiteralResultElement)

getAttributeList

public AttributeCollection getAttributeList()

Get the attribute list for this element.

getAttributeList in class ElementImpl

Returns:

The attribute list. This will not include any namespace attributes. The attribute names will be in expanded form, with prefixes replaced by URIs

hasAttributes

public boolean hasAttributes()

Returns whether this node (if it is an element) has any attributes.

Specified by:

hasAttributes in interface Node

Overrides:

getAttributeValue

public String getAttributeValue(String uri,
                       String localName)

Find the value of a given attribute of this node.
This method is defined on all nodes to meet XSL requirements, but for nodes other than elements it will always return null.

Specified by:

getAttributeValue in interface NodeInfo

Overrides:

getAttributeValue in class NodeImpl

Parameters:

uri - the namespace uri of an attribute

localName - the local name of an attribute

Returns:

the value of the attribute, if it exists, otherwise null

getAttributeValue

public String getAttributeValue(String name)

Find the value of a given attribute of this element.
This is a short-cut method; the full capability to examine attributes is offered via the getAttributeList() method.
The attribute may either be one that was present in the original XML document, or one that has been set by the application using setAttribute().

Overrides:

getAttributeValue in class ElementImpl

Parameters:

name - the name of an attribute. There must be no prefix in the name.

Returns:

the value of the attribute, if it exists, otherwise null

getAttributeValue

public String getAttributeValue(int fingerprint)

Get the value of a given attribute of this node

Specified by:

getAttributeValue in interface NodeInfo

Overrides:

getAttributeValue in class NodeImpl

Parameters:

fingerprint - The fingerprint of the attribute name

Set the value of an attribute on the current element. This affects subsequent calls of getAttribute() for that element.

Specified by:

setAttribute in interface Element

Overrides:

setAttribute in class ElementImpl

Parameters:

name - The name of the attribute to be set. Any prefix is interpreted relative to the namespaces defined for this element.

value - The new value of the attribute. Set this to null to remove the attribute.

Throws:

DOMException - (always): Saxon trees are immutable.

public void copy(Outputter out,
        boolean allNamespaces)
          throws TransformerException

Copy this node to a given outputter (supporting xsl:copy-of)
