What is this?
XML output uses tagged trees — useful when legacy systems, SOAP integrations, or strict hierarchical docs expect angle-bracket structure.
Why should you care?
PromptVerse export to some ERP connectors still expects XML fragments for line items.
See it live — copy this example
Copy the prompt into ChatGPT, Claude, or your LLM API playground and compare outputs.
Return XML only, root <ticket_analysis>:
<ticket_analysis>
<intent>billing</intent>
<priority>3</priority>
<summary>One sentence.</summary>
</ticket_analysis>
No text outside root tag.What happened?
- Root tag and child elements match ERP parser.
- "No text outside" prevents markdown pollution.
Practice next
- Define root and 3 child tags.
- Parse with DOMParser or fast-xml-parser.
- Reject if extra text outside root.
- Add attribute version="1" on root.
- Namespace prefix for enterprise bus.
Remember
XML suits legacy integrations. Declare root element. Validate parse before downstream.
ERP handoff
Finance system ingests ticket analysis.
Outcome: XML fragment drops into existing XSLT pipeline.
