Description

Interface Summary
AxisEnumeration: A NodeEnumeration is used to iterate over a list of nodes.
DocumentInfo: The root node of an XPath tree.
NodeEnumeration: A NodeEnumeration is used to iterate over a list of nodes.
NodeInfo: A node in the XML parse tree representing an XML element, character content, or attribute.

Class Summary
AbstractNode: This class is an abstract implementation of the Saxon NodeInfo interface; it also contains concrete implementations of most of the DOM methods in terms of the NodeInfo methods.
Axis: An axis, that is a direction of navigation in the document structure.
Builder: The abstract Builder class is responsible for taking a stream of SAX events and constructing a Document tree.
DocumentBuilderFactoryImpl: Implementation of JAXP 1.3 DocumentBuilderFactory.
DocumentBuilderImpl
DocumentPool: An object representing the collection of documents handled during a single transformation
EmptyEnumeration: EmptyEnumeration: an enumeration of an empty node-set
Name: This class, a remnant of its former self, exists to contain some static methods for validating the syntax of names.
NamePool: An object representing a collection of XML names, each containing a Namespace URI, a Namespace prefix, and a local name; plus a collection of namespaces, each consisting of a prefix/URI pair.
Namespace: An object representing a Namespace
Navigator: Navigator provides helper classes for navigating a tree, irrespective of its implementation
PrependIterator: An iterator over nodes, that prepends a given node to the nodes returned by another iterator.
ProcInstParser: ProcInstParser is used to parse pseudo-attributes within Processing Instructions
SingletonEnumeration: SingletonEnumeration: an enumeration of zero or one nodes
Stripper: The Stripper class maintains details of which elements need to be stripped.
XMLChar: This class defines the basic XML character properties.

Exception Summary
NamespaceException: A NamespaceException represents an error condition whereby a QName (e.g.

## Package com.icl.saxon.om Description

This package defines the interface to the Saxon tree structure. This structure is used to represent both the source document and the stylesheet.

The classes represent the various kinds of node on the tree. They implement the relevant DOM interfaces, but they are intended primarily to be used to reflect the XPath tree model rather than the DOM model.

The package also contains, for convenience, the Name class, which represents a namespace-qualified name.
