Part VIII Appendixes
mm-layout, mm:layout
Description
Used to specify which layout files should be applied to a request page. Layout files are essentially
XHTML or JSP files that contain a description of how output content is best arranged for a
specific device or for certain classes of devices. This tag is placed inside the <head> element. It
is an empty tag, so it requires a slash (/) before the final angle bracket (>).
Attributes
•
where="..."
The where attribute enables the author to specify content selection conditions for devices.
Notes
•
where="IsFullBrowser" is not allowed with this tag
•
The "where" clause quoted string must not contain line breaks
•
Conditions are constructed by specifying device attribute names and allowable values,
using comparison operators from the Python programming language. Multiple conditions can
be combined to make complex expressions by using the logical "and", "or" and "not"
operators from Python.
•
WebLogic Mobility Server also supports use of the Python .endswith( ), .startswith( )
and .find( ) methods for partial matching.
Restrictions
•
At least one condition must be specified
•
Attribute names must be valid as taken from the Device Repository
•
All String attribute values must be wrapped in single quotes
•
src="url"
A URL that points WebLogic Mobility Server to the layout file.
Example
<!-- The following example targets a distinct type of device with a specific
layout. -->
