Filtering data

Use native filters, which are preferred, or IBM® Rational® Publishing Engine filters to limit the amount of processed data. Not all data sources support native filters.

There are two ways to filter data:

Note: The native filter must to be a valid filter as defined by the data source. No validation is performed. An invalid filter might produce results ranging from incorrect data in the output to the tool crashing.

Not all data sources support native filtering. You cannot define a native filter for data sources accessed through the Generic XML input driver of Rational Publishing Engine. The only exception is for the data sources where the filtering can be specified in the URL.

Tip: Use native filters whenever possible. Native filters are usually more effective and generate document faster than Rational Publishing Engine filters.
