This is something you will have to take up with Support.

You're security tool is missinterpreting this. This is not PHP. These are standard XML processing instructions.
RoboHelp output is not using any PHP.
Since we used the Responsive HTML5 output format, we expected the results to be only as HTML files.
Why are the XML instructions part of the HTML files?
Do you have an example where PIs appear in the Responsive HTM5 output?
I just tested it with a couple of sample projects I have and could not find any PIs in the published output except for the XML declaration itself in line 1.
That said: RoboHelp does not only produce simple HTML5, but HTML5 in an XML notation. That is, the output is not only HTML5 compliant, but also 100% XML compliant.
Thank you for the information @Stefan-Gentz . I'll make use of this info for our test report.
To answer your question, those PIs were displayed in the index.html file generated via Responsive HTML option.
Please refer below image for more information.
Hm. This is in the output? I have never seen this in the HTML5 output. I cannot even find any of this in any file in my project nor anywhre in the output.
That said, the best might be to contact the RoboHelp Support team: firstname.lastname@example.org
I have never seen it in the output.
I would try generating with the sample project supplied with RH to see if the output created by that has the same lines you note. If it doesn't, then that means that there's something else going on in your project that's creating those lines.
Also make sure you are all patched up - you didn't mention what exact version of RH2019 you're running.
