How to fetch placeholder text from a document-based authoring system (EDS) for use in a form field?

Hi,

I’m working in a document-based authoring environment where content is managed through structured documents (possibly XML or JSON via an Enterprise Data Store). I need to fetch the placeholder text for an email input field dynamically from the EDS document and display it in a web form (as shown in the attached screenshot).

Could someone help me understand:

1. How do I retrieve the placeholder text value from a structured document in the EDS?

   • What tags or keys should I look for (assuming XML/JSON)?

2. What is the recommended approach to bind this value to a frontend form field's placeholder attribute?

3. Are there specific APIs, query mechanisms, or CMS features used to extract such values in document-based systems?

4. How do I ensure this content remains manageable for authors/editors without needing code changes?

Any guidance, best practices, or example implementations would be really helpful.

Thanks!
