You can use different different map:pipeline sections to:
(1) Allow each map:pipeline to define its own error handling va
map:handle-errors. Example:
<map:pipeline>
<map:match pattern="foo">...</map:match>
<map:handle-errors>
<!-- use one transform/serializer -->
</map:handle-errors>
</map:pipeline>
<map:pipeline>
<map:match pattern="bar">...</map:match>
<map:handle-errors>
<!-- use another transform/serializer -->
</map:handle-errors>
</map:pipeline>
(2) Hide a map:pipeline from external target requests (e.g., web
browsers cannot request the "foo" target) by using the
internal-only="true" attribute/value. Example:
<map:pipeline internal-only="true">
<map:match pattern="foo">...</map:match>
</map:pipeline>
<map:pipeline>
<map:match pattern="bar">
<map:generate src="cocoon:/foo"/>
...
</map:match>
</map:pipeline>
(3) Use a different map:pipeline type for some targets such as
type="profile-caching" to use caching and profiling. Example:
<!-- profiled targets -->
<map:pipeline type="profile-caching">
<map:match pattern="foo">...</map:match>
<!-- more profiled targets -->
...
</map:pipeline>
<!-- non-profiled targets -->
<map:pipeline>
<map:match pattern="bar">...</map:match>
<!-- don't profile the profile -->
<map:match pattern="profile">
<map:generate type="profile"/>
<!-- we could use XSL to stylize here -->
<!-- but we will just show current raw profile results -->
<map:serialize type="xml"/>
</map:match>
</map:pipeline>
Requests for "foo" are shown in the profile. Use the <map:generate
type="profile"/> generator in a pipeline target to
(4) Any or all of the above in combination
An excellent discussion of pipelines can be found in Matthew and
Carsten's Coocon book by New Riders () on page 75.
Is this a good candidate for the Wiki?
