Interface StartElement

All Superinterfaces:

XMLEvent, XMLStreamConstants

public interface StartElement
extends XMLEvent

The StartElement interface provides access to information about start elements. A StartElement is reported for each Start Tag in the document.

Since:

1.6

void	writeAsEncodedUnicode(Writer writer)	This method will write the XMLEvent as per the XML 1.0 specification as Unicode characters.

Method Details

getName

QName getName()

Get the name of this event

Returns:

the qualified name of this event

getAttributes

Iterator<Attribute> getAttributes()

Returns an Iterator of non-namespace attributes declared on this START_ELEMENT. Returns an empty iterator if there are no attributes. The iterator must contain only implementations of the Attribute interface. Attributes are fundamentally unordered and may be reported in any order.

Returns:

a readonly Iterator over Attribute interfaces, or an empty iterator

getNamespaces

Iterator<Namespace> 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 Namespace interface.

A Namespace is an 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 the qname.

Parameters:

name - the qname of the desired attribute

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
