Pre-processing extension points

You can use these extension points to run an Ant target before or after the pre-processing stage. If necessary, you can also run an Ant target before a specific pre-processing step — but this approach is not recommended.

Tip: For maximum compatibility with future versions of DITA-OT, most plug-ins should use the extension points that run before or after pre-processing.

depend.preprocess.pre
Runs an Ant target before the pre-processing stage.
depend.preprocess.post
Runs an Ant target after the pre-processing stage.

Legacy pre-processing extensions

The following extension points are available in the original preprocess pipeline that was used by default for all transformations prior to DITA-OT 3.0. These extensions are not available in the newer map-first preprocessing pipeline (preprocess2), which is used in the PDF and HTML Help transformations as of DITA-OT 3.0.

CAUTION:

The internal order of preprocessing steps is subject to change between versions of DITA-OT. New versions may remove, reorder, combine, or add steps to the process, so the extension points within the preprocessing stage should only be used if absolutely necessary.
