Method Detail

attribute

public Attribute attribute(java.lang.String name)

Description copied from interface: Element

Returns the attribute with the given name

Specified by:

attribute in interface Element

Overrides:

attribute in class DefaultElement

Parameters:

name - DOCUMENT ME!

Returns:

the attribute for the given local name in any namespace. If there are more than one attributes with the given local name in different namespaces then the first one is returned.

attribute

public Attribute attribute(QName qName)

Description copied from interface: Element

DOCUMENT ME!

Specified by:

attribute in interface Element

Overrides:

attribute in class DefaultElement

Parameters:

qName - is the fully qualified name

Returns:

the attribute for the given fully qualified name or null if it could not be found.

element

public Element element(java.lang.String name)

Description copied from interface: Element

Returns the first element for the given local name and any namespace.

Specified by:

element in interface Element

Overrides:

element in class DefaultElement

Parameters:

name - DOCUMENT ME!

Returns:

the first element with the given local name

element

public Element element(QName qName)

Description copied from interface: Element

Returns the first element for the given fully qualified name.

Specified by:

element in interface Element

Overrides:

element in class DefaultElement

Parameters:

qName - is the fully qualified name to search for

Returns:

the first element with the given fully qualified name

elements

public java.util.List<Element> elements(java.lang.String name)

Description copied from interface: Element

Returns the elements contained in this element with the given local name and any namespace. If no elements are found then this method returns an empty list. The list is backed by the element such that changes to the list will be reflected in the element though the reverse is not the case.

Specified by:

elements in interface Element

Overrides:

elements in class AbstractElement

Parameters:

name - DOCUMENT ME!

Returns:

a list of all the elements in this element for the given local name

elements

public java.util.List<Element> elements(QName qName)

Description copied from interface: Element

Returns the elements contained in this element with the given fully qualified name. If no elements are found then this method returns an empty list. The list is backed by the element such that changes to the list will be reflected in the element though the reverse is not the case.

Specified by:

elements in interface Element

Overrides:

elements in class AbstractElement

Parameters:

qName - is the fully qualified name to search for

Returns:

a list of all the elements in this element for the given fully qualified name.

asElement
