Find files with duplicate topic titles in a ditamap

[kj_rk]

Hi Oxygen team,
Is there a way to list all the files in a ditamap or bookmap that have the same topic title?
I tried looking for some custom actions, but found "find.similar.topics". But, I am looking for something to match the titles exactly.
If there is a way to do this using Schematron, would you kindly provide the check?

Thanks

Hi,
We do not have such a custom action. And Schematron does not help because it is applied on each individual topic.
For such an action to work you would need to collect all titles from all topics in the DITA Map. For each title you would also need to have a counter of how many times the title is repeated.
If I were to attempt to find out something like this, I would first open the DITA Map in the DITA Maps Manager view, then use the "Configure Transformation Scenarios" toolbar button and in the Configure Transformation Scenarios" dialog use "New->DITA OT transformation" and create a transformation scenario of type "Merge DITA content to single XML file". Then execute the transformation scenario and you will have one big XML file where all the topicrefs are expanded. Then I would create a custom XSLT stylesheet to count titles.

Radu
