Class Axis

      +--org.apache.xml.dtm.Axis

public final class Axis
extends java.lang.Object

Specifies values related to XPath Axes.

The ancestor, descendant, following, preceding and self axes partition a document (ignoring attribute and namespace nodes): they do not overlap and together they contain all the nodes in the document.

Field Summary
`static int` | `ALL` A non-xpath axis, returns all nodes in the tree from and including the root.
`static int` | `ALLFROMNODE` A non-xpath axis, traversing the subtree including the subtree root, descendants, attributes, and namespace node decls.
`static int` | `ANCESTOR` The ancestor axis contains the ancestors of the context node; the ancestors of the context node consist of the parent of context node and the parent's parent and so on; thus, the ancestor axis will always include the root node, unless the context node is the root node.
`static int` | `ANCESTORORSELF` the ancestor-or-self axis contains the context node and the ancestors of the context node; thus, the ancestor axis will always include the root node.
`static int` | `ATTRIBUTE` the attribute axis contains the attributes of the context node; the axis will be empty unless the context node is an element.
`static int` | `CHILD` The child axis contains the children of the context node.
`static int` | `DESCENDANT` The descendant axis contains the descendants of the context node; a descendant is a child or a child of a child and so on; thus the descendant axis never contains attribute or namespace nodes.
`static int` | `DESCENDANTORSELF` The descendant-or-self axis contains the context node and the descendants of the context node.
`static int` | `DESCENDANTSFROMROOT` A non-xpath axis, returns all nodes that aren't namespaces or attributes, from and including the root.
`static int` | `DESCENDANTSORSELFFROMROOT` A non-xpath axis, returns all nodes that aren't namespaces or attributes, from and including the root.
`static int` | `FILTEREDLIST` A non-xpath axis, for functions.
`static int` | `FOLLOWING` the following axis contains all nodes in the same document as the context node that are after the context node in document order, excluding any descendants and excluding attribute nodes and namespace nodes.
`static int` | `FOLLOWINGSIBLING` The following-sibling axis contains all the following siblings of the context node; if the context node is an attribute node or namespace node, the following-sibling axis is empty.
`static int` | `NAMESPACE` The namespace axis contains the namespace nodes of the context node; the axis will be empty unless the context node is an element.
`static int` | `NAMESPACEDECLS` The namespace axis contains the namespace nodes of the context node; the axis will be empty unless the context node is an element.
`static int` | `PARENT` The parent axis contains the parent of the context node, if there is one.
`static int` | `PRECEDING` The preceding axis contains all nodes in the same document as the context node that are before the context node in document order, excluding any ancestors and excluding attribute nodes and namespace nodes
`static int` | `PRECEDINGANDANCESTOR` A non-xpath axis, traversing the the preceding and the ancestor nodes, needed for inverseing select patterns to match patterns.
`static int` | `PRECEDINGSIBLING` The preceding-sibling axis contains all the preceding siblings of the context node; if the context node is an attribute node or namespace node, the preceding-sibling axis is empty.
`static int` | `ROOT` A non-xpath axis, returns root only.
`static int` | `SELF` The self axis contains just the context node itself.

Field Detail

### ANCESTOR

    public static final int ANCESTOR

  The ancestor axis contains the ancestors of the context node; the ancestors of the context node consist of the parent of context node and the parent's parent and so on; thus, the ancestor axis will always include the root node, unless the context node is the root node.

### ANCESTORORSELF

    public static final int ANCESTORORSELF

  the ancestor-or-self axis contains the context node and the ancestors of the context node; thus, the ancestor axis will always include the root node.

### ATTRIBUTE

    public static final int ATTRIBUTE

  the attribute axis contains the attributes of the context node; the axis will be empty unless the context node is an element.

### CHILD

    public static final int CHILD

  The child axis contains the children of the context node.

### DESCENDANT

    public static final int DESCENDANT

  The descendant axis contains the descendants of the context node; a descendant is a child or a child of a child and so on; thus the descendant axis never contains attribute or namespace nodes.

### DESCENDANTORSELF

    public static final int DESCENDANTORSELF

  The descendant-or-self axis contains the context node and the descendants of the context node.

### FOLLOWING

    public static final int FOLLOWING

  the following axis contains all nodes in the same document as the context node that are after the context node in document order, excluding any descendants and excluding attribute nodes and namespace nodes.

### FOLLOWINGSIBLING

    public static final int FOLLOWINGSIBLING

  The following-sibling axis contains all the following siblings of the context node; if the context node is an attribute node or namespace node, the following-sibling axis is empty.

### NAMESPACEDECLS

    public static final int NAMESPACEDECLS

  The namespace axis contains the namespace nodes of the context node; the axis will be empty unless the context node is an element.

### NAMESPACE

    public static final int NAMESPACE

  The namespace axis contains the namespace nodes of the context node; the axis will be empty unless the context node is an element.

### PARENT

    public static final int PARENT

  The parent axis contains the parent of the context node, if there is one.

### PRECEDING

    public static final int PRECEDING

  The preceding axis contains all nodes in the same document as the context node that are before the context node in document order, excluding any ancestors and excluding attribute nodes and namespace nodes

### PRECEDINGSIBLING

    public static final int PRECEDINGSIBLING

  The preceding-sibling axis contains all the preceding siblings of the context node; if the context node is an attribute node or namespace node, the preceding-sibling axis is empty.

### SELF

    public static final int SELF

  The self axis contains just the context node itself.

### ALLFROMNODE

    public static final int ALLFROMNODE

  A non-xpath axis, traversing the subtree including the subtree root, descendants, attributes, and namespace node decls.

### PRECEDINGANDANCESTOR

    public static final int PRECEDINGANDANCESTOR

  A non-xpath axis, traversing the the preceding and the ancestor nodes, needed for inverseing select patterns to match patterns.

### ALL

    public static final int ALL

  A non-xpath axis, returns all nodes in the tree from and including the root.

### DESCENDANTSFROMROOT

    public static final int DESCENDANTSFROMROOT

  A non-xpath axis, returns all nodes that aren't namespaces or attributes, from and including the root.

### DESCENDANTSORSELFFROMROOT

    public static final int DESCENDANTSORSELFFROMROOT

  A non-xpath axis, returns all nodes that aren't namespaces or attributes, from and including the root.

### ROOT

    public static final int ROOT

  A non-xpath axis, returns root only.

### FILTEREDLIST

    public static final int FILTEREDLIST

  A non-xpath axis, for functions.
