Better prompts through XML prompting

If you regularly work with AI-supported systems - whether for text generation, customer communication or data processing - you know: The quality of the output depends largely on how you formulate the input. In previous articles, we have already looked at some prompting methods. These each had their own use cases, advantages and disadvantages. Today we'll look at a method that is a little more general but no less useful. This method brings clarity and structure to your prompts: XML-Prompting.

What is XML-Prompting?

Instead of writing your instructions in free text form, you structure them with XML tags. This then looks something like this:

<prompt>
  <instruction>Write a newsletter about sustainable nutrition</instruction>
  <audience>Young adults</audience>
  <language>German</language>
  <tone>Inspiring, motivating</tone>
</prompt>

The goal? Tell the AI clearly what you want, for whom and how. With this semantic clarity, you make it easier for the model to understand your intent precisely - and get much more relevant results.

When is XML prompting worthwhile for you?

If you have recurring tasks - for example when generating product descriptions, FAQs or blog articles - you can work with XML prompts in the same way as with templates. You simply change individual pieces of content without having to rewrite the entire structure.

XML is also a real benefit when working with teams or in automated systems . You can standardize prompts, transfer them to APIs or integrate them into no-code platforms. This reduces misunderstandings - for both humans and machines.

But: Not always the best choice

If you simply need a quick answer or want the AI to think creatively - for example when brainstorming campaign ideas or stories - then XML is often too cumbersome. In such cases, a well-formulated free-text prompt is more flexible.

Clarity creates quality

XML prompting is not a technical end in itself, but a means of making your AI queries clear, comprehensible and repeatable . Especially in professional environments where consistency counts, this method gives you a real advantage.

The next time you use an AI, think: could a structured prompt simplify the task? Perhaps XML prompting is exactly the lever you need to take your results to the next level.
