Method Detail

getBaseUri

public static java.lang.String getBaseUri(ElementContext context)

Obtains a base URI from any xml:base value in scope, or from any available SAX Locator as a fallback. This relies upon an XMLContextAttributes object having been setup to filter context events.

Returns:

a base URI, or null if no xml:base is in scope and no system ID from a Locator is available.

getLocale

public static java.util.Locale getLocale(ElementContext context)

Creates a Java Locale object representing any xml:lang value in scope. This relies upon an XMLContextAttributes object having been setup to filter context events.

Returns:

a corresponding Locale object, or null if no xml:lang is in scope.

startElement

public void startElement(StartElementEvent event)
                  throws EventContextException

Overrides:

startElement in class ContextAdapter
