      • channelSynonymes

        private java.lang.String[][] channelSynonymes
        The channelSynonymes consists of an array of identifiers. The first element of the array is the name that you want filled. The others names are synonymes that might be filled. These are all synonymes for channel attributes, for instance, you need the title attribute. If this isnt found initially, this class will look for an rss:title attribute. If found, it will copy the value of rss:title to title. These values could be moved out into a properties kind of file, e.g. url=link,dc:indentifier,rss:link
