Json transformation fails due to default xsl files

Hello,
I am trying to publish the topics in my ditamap to a single xml or json file to be used by a help gadget that is embedded in the product. The file will contain topics that each have unique reference IDs which are used to created context-sensitive tool tips.
Anyway, I have created a new transformation DITA-OT json transformation scenario using the stock settings, but keep getting the following fatal errors:
Code: Select all
System ID: C:\Program Files\Oxygen XML Editor 20\frameworks\dita\DITA-OT2.x\plugins\org.dita-community.common.xslt\xsl\dita-support-lib.xsl

I haven't modified any of these .xsl files.
Also, my expectation is that this would generate a single json file with all the topics. My team could just as easily use an .xml file with all the resolved topics in raw XML. Is there a better way to do this?
Thanks in advance!

Hi,
I'm not sure what the problem is, can you maybe send us (
support@oxygenxml.com) a link to download the DITA OT plugin and test it on our side? Does your plugin come with Java libraries or is it pure XSLT?
About this remark:

One option would be to set on the main DITA Map <map> root element the "chunk='to-content'" attribute.
Another option would be to use the "DITA-OT2.x/plugins/com.oxygenxml.merged" plugin which comes pre-installed and which outputs a single merged XML document. Maybe you can modify the plugin to also apply an XSLT stylesheet over the merged XML and produce the JSON.

Radu

Hi Radu,
I'm using what I think is just a default transformation scenario in the toolkit. I went to Transformation Scenarios > New > DITA OT transformation > json. The thing is - I don't think I need a stylesheet because I just want the raw xml from the topics to be compiled in a single file.

I'd love to learn more about this. I actually already have the chunk='to-content" attribute set on the map tag. How do I find the xml.merged transform? I don't see the option.
Thanks!

Radu,
I'm thinking I might need to install this plug-in (in 20.1):
https://github.com/oxygenxml/dita-merged
I'm not sure how to do that though.
Thanks,
Jesse

Radu,
As followup, I was able to use the Merge DITA content to single file transform to make the xml and then the convert it to json in Oxygen (downloaded the plug-in for that). Very slick!
Thanks again for your help.

Hi Jesse,
Great, I should have given you more details about how to create a new merge transformation by using in the Transformation Scenario dialog "New->DITA-OT" and choosing Merge DITA content to single file so sorry about that.
Out of curiosity what are your plans with the JSON file afterwards? Do you need to obtain a very specific JSON structure and thus need to process the XML further before the conversion to JSON?

Radu

Radu,
No worries. I might suggest, however, changing "Merge DITA content to single file" in the UI to something like, "Merge DITA content to single
XML file" so that it's more clear that that's what you are doing.
The json file is going to be sitting in our company's main software build, and its contents will be called to populate little pop-up help snippets (basically tool tips), and those snippets may link out to our greater, Drupal-based (but DITA-sourced) help center. Each topic has a unique reference ID that is used to link the topic to its appropriate location in the UI.
I have passed the json file off to the development team for testing. It remains to be seen if they will need further formatting, but I will keep you posted.
Thanks again for your help!

Hi Jesse,
Thanks for the feedback, I'll add an internal issue to rename the DITA to merged XML transformation type description so that it more accurately states that an XML file is obtained.

Hi,
As an update, in the Oxygen 23.1 version we just released the transformation type is named "Merge DITA content to single XML file".
