Class DocumentFactory

java.lang.Object

org.dom4j.DocumentFactory

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

BeanDocumentFactory, DatatypeDocumentFactory, DatatypeElementFactory, DOMDocumentFactory, IndexedDocumentFactory, NonLazyDocumentFactory, UserDataDocumentFactory

public class DocumentFactory
extends Object
implements Serializable

DocumentFactory is a collection of factory methods to allow easy custom building of DOM4J trees. The default tree that is built uses a doubly linked tree.

The tree built allows full XPath expressions from anywhere on the tree.

createXPath

public XPath createXPath(String xpathExpression)
                  throws InvalidXPathException

createXPath parses an XPath expression and creates a new XPath XPath instance.

Parameters:

xpathExpression - is the XPath expression to create

Returns:

a new XPath instance

Throws:

InvalidXPathException - if the XPath expression is invalid

createXPath

public XPath createXPath(String xpathExpression,
                org.jaxen.VariableContext variableContext)

createXPath parses an XPath expression and creates a new XPath XPath instance.

Parameters:

createXPathFilter

public NodeFilter createXPathFilter(String xpathFilterExpression,
                           org.jaxen.VariableContext variableContext)

variableContext - is the variable context to use when evaluating the XPath

Returns:

createXPathFilter

public NodeFilter createXPathFilter(String xpathFilterExpression)

createXPathFilter parses a NodeFilter from the given XPath filter expression. XPath filter expressions occur within XPath expressions such as self::node()[ filterExpression ]

getXPathNamespaceURIs

public Map getXPathNamespaceURIs()

DOCUMENT ME!

Returns:

the Map of namespace URIs that will be used by by XPath expressions to resolve namespace prefixes into namespace URIs. The map is keyed by namespace prefix and the value is the namespace URI. This value could well be null to indicate no namespace URIs are being mapped.

setXPathNamespaceURIs

public void setXPathNamespaceURIs(Map namespaceURIs)
