Name

QName

Synopsis

A QName represents an XML “qualified name,” such as an XML element name that has both a local name and a namespace. getLocalPart( ) returns the unqualified local part of the name. getNamespaceURI( ) returns the canonical URI that formally identifies the namespace. getPrefix( ) returns the locally declared namespace prefix. Note that a QName does not always have a prefix and that the prefix, if it exists, is ignored for the purposes of the equals( ), hashCode( ), and toString( ) methods. The static valueOf( ) method parses a QName from a string in the format of toString( ):

{namespaceURI}localPart
