- Returns:
- The URI of the namespace of this node. For an unnamed node, or for a node with an empty prefix, return an empty string.

getSiblingPosition
in interfaceSiblingCountingNode
- Returns:
- 0 for the first child, 1 for the second child, etc.
-
iterateAttributes

iterateAttributes
in classAbstractNodeWrapper
- Parameters:
nodeTest

- an iterator over the attribute nodes. The order of the result, although arbitrary, must be consistent with document order.
-
iterateChildren

Return an iterator over the children of this node. This method is only called after checking that the node is an element or document.- Specified by:
iterateChildren

- the attribute value if it exists, or null if it does not exist. Always returns null if this node is not an element.
- Since:
- 8.4
-
getRoot
Get the root node - always a document node with this tree implementation- Specified by:
getRoot
in interfaceNodeInfo
- Overrides:
getRoot
in classAbstractNodeWrapper
- Returns:
- the NodeInfo representing the containing document
-
hasChildNodes
public boolean hasChildNodes()Determine whether the node has any children.Note: the result is equivalent to
getEnumeration(AxisInfo.CHILD, AnyNodeTest.getInstance()).hasNext()
- Specified by:
hasChildNodes
in interfaceNodeInfo
- Overrides:
hasChildNodes
in classAbstractNodeWrapper
- Returns:
- True if the node has one or more children

generateId
Get a character string that uniquely identifies this node. Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)- Specified by:
generateId
in interfaceNodeInfo
- Parameters:
buffer
- a Buffer to contain a string that uniquely identifies this node, across all documents
-
getDeclaredNamespaces
Get all namespace undeclarations and undeclarations defined on this element.- Specified by:
getDeclaredNamespaces
in interfaceNodeInfo
- Overrides:
getDeclaredNamespaces
in classAbstractNodeWrapper
- Parameters:
buffer
- If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.- Returns:
- An array of namespace binding objects representing the namespace declarations and undeclarations present on
this element. For a node other than an element, return null.
If the uri part is "", then this is a namespace undeclaration rather than a declaration.
The XML namespace is never included in the list. If the supplied array is larger than required,
then the first unused entry will be set to null.
For a node other than an element, the method returns null.
-
getAllNamespaces
Get all the namespace bindings that are in-scope for this element.For an element return all the prefix-to-uri bindings that are in scope. This may include a binding to the default namespace (represented by a prefix of ""). It will never include "undeclarations" - that is, the namespace URI will never be empty; the effect of an undeclaration is to remove a binding from the in-scope namespaces, not to add anything.
For a node other than an element, returns null.
- Specified by:
getAllNamespaces
in interfaceNodeInfo
- Overrides:
getAllNamespaces
in classAbstractNodeWrapper
- Returns:
- the in-scope namespaces for an element, or null for any other kind of node.

isId
public boolean isId()Determine whether this node has the is-id property -
isIdref
public boolean isIdref()Determine whether this node has the is-idref property
