Converts a lexical dateTime, as defined by XML Schema 1.0, into milliseconds since the epoch.

Parameters:

dateTime - lexical date/time, may not be null

Returns:

the date/time expressed as milliseconds since the epoch

durationToLong

public static long durationToLong(java.lang.String duration)

Converts a lexical duration, as defined by XML Schema 1.0, into milliseconds.

Parameters:

duration - lexical duration representation

Returns:

duration in milliseconds

durationToLong

public static long durationToLong(javax.xml.datatype.Duration duration)

Converts a lexical duration, as defined by XML Schema 1.0, into milliseconds.

Parameters:

duration - JAXP duration representation

Returns:

duration in milliseconds

getDataTypeFactory

public static javax.xml.datatype.DatatypeFactory getDataTypeFactory()

Gets a static instance of a JAXP DatatypeFactory.

Returns:

the factory or null if the factory could not be created

getXSIType

@Nullable
public static javax.xml.namespace.QName getXSIType(@Nullable
                                                             org.w3c.dom.Element e)
