Class 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

      Fields 
      Modifier and Type Field Description
      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.
