Oxygen XML Forum

Historically (sorry, I can't cite a specific Oxygen XML Author version), when I duplicated a DITA topic and saved the duplicate with a new file name, such as prodx-intro.dita (note the hyphen in the file name), Author automatically set the root element id attribute value to the file name without the file extension. For example: id="prodx-intro". I liked that.

However, when generating the id attribute, Author 26.1 replaces hyphens in the file name with underscores. For example: id="prodx_intro". I don't like that.

I know how to "revert" this unwanted behavior:

1. Select Options > Preferences > DITA > Topics
2. Under New Topics: "Use the title to generate the file name", which is selected by default, change the value of "Replace non-alphanumeric characters" from an underscore (_) to a hyphen (-).

Note: "Use the file name as the value of the root ID attribute" is selected by default.

I'm bothering writing about this for a few reasons, including:

• I don't like this fix. It feels like a hack. It doesn't feel right to me to change a suboption of "Use the title to generate the file name" to change the generated id attribute value when, in my case, I'm manually specifying the file name.
• I'm wondering if this change in behavior is due to a change in the "proprietary" DITA framework I'm using rather than a change in Author itself. I'm using Author to edit DITA topics that use organization-specific DITA DTDs. That organization used to supply an installation of Author precustomized for those DTDs. However, recently, that organization changed to supplying a separate, cut-down version of those customizations that now have to be applied post-install. Possibly related: when I select Refactoring > XML Refactoring, I now no longer see "Change topic ID to file name" as a refactoring operation for DITA topics with these organization-specific DTDs.

Is there a different, "cleaner" (non-hack-y) customization that I can make to revert this unwanted "new" behavior?

Hello Graham,
Indeed in Oxygen 26.1 we had a change in behavior in this regard as before Oxygen 26.1 the generated IDs would always contain "_" inside them and we had users who wanted to be able to control them to be "-" hyphen instead. Maybe we should have added a separate setting, I added an internal issue based on your report, pasting the issue ID below for future reference:
EXM-55055 Duplicate DITA topic - default ID generation settings changed
If we fix the issue in a future version we will update this forum thread.
In the meantime you can use the setting you discovered.

The lack of this specific XML refactoring is probably related to the fact you have a custom DITA framework which no longer ships it, this being a separate problem than the generation of the ID value you mentioned above.

Thanks for the confirmation/clarification and for creating that internal issue. Just my opinion: yes, I think a separate setting would be "cleaner".

Yes, I wasn't sure about that, thanks for the advice.

Very helpful, detailed response as always, Radu. Thank you!
