Using DITA OT 1.8.5 base EPUB plugin named "org.dita4publishers.epub".
Out put i am getting all the the topics which are in dita map file but i want to omit the topic_2 in the epub output generated using epub plugin in oxygen.
In the DITA Map on the topicref to "topics/topic_2.dita" you can add a profiling attribute like 'product="X"' and then create a Ditaval filter file (which you can name for example "filter.xml") having the content like:
<val>
<prop action="exclude" att="product" val="X"/>
</val>
Then edit (or duplicate and edit) the Oxygen transformation scenario and it has a "Filters" tab where you can add a reference to the Ditaval filter file. As an alternative in the same "Filters" tab you have a table where you can add exclude conditions.
