DateSelector in Cocoon

The DateSelector tests the current date, and time against the test attribute of the selectors when clause.

The DateSelector allows to define date, and time specific sitemap processing. This way Cocoon can do date, and time specific sitemap processing.

Sitemap pipeline examples

<map:select type="daytime">
  <map:when test="night">
    <!-- do something for night publishing -->
    <map:read src="resources/{2}-night.css" mime-type="text/css>
  </map:when>
  <map:when test="morning">
    <!-- do something for morning publishing -->
    <map:read src="resources/{2}-morning.css" mime-type="text/css>
  </map:when>
  ...
  <map:otherwise>
    <!-- define for completness, and if selecting fails due to errors -->
  </map:otherwise>
</map:select>

Sitemap component configuration example

The following snippet defines a DateSelector named daytime. A day is partioned into four daytime areas: night, morning, afternoon, and evening. These daytime names are used to define daytime specific pipeline processing for each daytime area.

<map:selectors default="browser">
  ...
  <map:selector type="daytime" src="org.apache.cocoon.selection.DateSelector">
    <before name="night" date="06:00:00" dateformat="HH:mm:ss"/>
    <before name="morning" date="12:00:00" dateformat="HH:mm:ss"/>
    <before name="afternoon" date="18:00:00" dateformat="HH:mm:ss"/>
    <before name="evening" date="23:59:59" dateformat="HH:mm:ss"/>
  </map:selector>
...
</map:selectors>
