Method Detail

getName

QName getName()

Get the name of this event

Returns:: the qualified name of this event

getAttributes

Iterator getAttributes()

Returns an Iterator of non-namespace declared attributes declared on this START_ELEMENT, returns an empty iterator if there are no attributes. The iterator must contain only implementations of the javax.xml.stream.Attribute interface. Attributes are fundamentally unordered and may not be reported in any order.

Returns:: a readonly Iterator over Attribute interfaces, or an empty iterator

getNamespaces

Iterator getNamespaces()

Returns an Iterator of namespaces declared on this element. This Iterator does not contain previously declared namespaces unless they appear on the current START_ELEMENT. Therefore this list may contain redeclared namespaces and duplicate namespace declarations. Use the getNamespaceContext() method to get the current context of namespace declarations.

The iterator must contain only implementations of the javax.xml.stream.Namespace interface.

A Namespace isA Attribute. One can iterate over a list of namespaces as a list of attributes. However this method returns only the list of namespaces declared on this START_ELEMENT and does not include the attributes declared on this START_ELEMENT. Returns an empty iterator if there are no namespaces.

Returns:: a readonly Iterator over Namespace interfaces, or an empty iterator

getAttributeByName

Attribute getAttributeByName(QName name)

Returns the attribute referred to by this name

Parameters:: name - the qname of the desired name
Returns:: the attribute corresponding to the name value or null

getNamespaceContext

NamespaceContext getNamespaceContext()

Gets a read-only namespace context. If no context is available this method will return an empty namespace context. The NamespaceContext contains information about all namespaces in scope for this StartElement.

Returns:: the current namespace context

getNamespaceURI

String getNamespaceURI(String prefix)

Gets the value that the prefix is bound to in the context of this element. Returns null if the prefix is not bound in this context

Parameters:: prefix - the prefix to lookup
Returns:: the uri bound to the prefix or null
