XML Generator
Generate random XML documents with custom structure
Input Information
Result
XML Generator creates well-formed random XML documents based on your specified element names and structure. Useful for testing XML parsers, SOAP services, and configuration file generation.
The generator produces valid XML with proper indentation, escaping special characters as needed, and supporting both element and attribute configurations.
Term Glossary
- XML
- Short for eXtensible Markup Language, a markup language that structures and transmits data using tags. Unlike HTML, users can define their own tags.
- Escaping
- In markup languages like XML, the process of converting special characters such as <, >, & into <, >, & so they are not confused with tags.
- 1
Choose a structure
Choose the root element and the repeated item structure for the XML you want to generate.
- 2
Enter values
Enter the element names and values for each field, optionally specifying attributes as well.

Generate XML
Click the button to generate a valid XML document with proper indentation and escaping.

Copy
Copy the generated XML to your clipboard for testing, saving, or use in API requests.
Example 1 — Simple element
<user> <name>Alice</name> <email>alice@example.com</email> </user>
Two field elements, <name> and <email>, are nested under the root element <user>. A single, non-repeated record is expressed with simple elements like this.
Example 2 — Nested list
<users>
<user>
<name>Alice</name>
<role>admin</role>
</user>
<user>
<name>Bob</name>
<role>editor</role>
</user>
</users>Repeated records are expressed as a list by repeating the <user> element under the <users> root. Keeping each item in the same structure lets XML parsers read the data consistently.
XML Structure:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item>
<fieldName>value</fieldName>
</item>
</root>- Root element: The outermost container element.
- Item elements: Each repeated record in the collection.
- Field elements: Individual data values within each record.
Tips:
- Use meaningful element names that describe your data structure.
- XML element names cannot contain spaces or start with numbers.
- The generator automatically escapes special XML characters (<, >, &, etc.).
- Useful for testing XML-based APIs and configuration files.
QWhat is the difference between XML and JSON?
XML is a tag-based markup language that is human-readable and supports complex structures like attributes, namespaces, and schemas (XSD). JSON is lightweight, machine-friendly, and fits naturally with JavaScript. XML suits document-centric, standards-driven scenarios (SOAP, XHTML), while JSON dominates web API data exchange.
QWhat are self-closing tags?
Self-closing tags express empty elements that have no children, written like <empty /> with a slash at the end of the start tag. In XML every element must be closed, so elements with no content must be written this way to produce well-formed XML.
QShould I use attributes or elements?
Attributes suit concise metadata or single values for an element, while elements suit repeated or hierarchical data. As a convention, store the data itself in elements and auxiliary descriptive information in attributes. This tool supports both, so choose according to your structure.
QHow are namespaces handled?
Namespaces prevent name collisions between elements from different sources. Declared with the xmlns attribute referencing a URI, elements sharing a name can coexist when they belong to different namespaces. The generator helps you produce documents with xmlns declarations as needed.
QWhen should I use XML instead of JSON?
XML remains widely used where complex document structure, comments, schema validation, and namespaces matter, and where interoperability with existing enterprise systems (SOAP services, XHTML, RSS/Atom feeds, regulated industries like finance and insurance) is critical. In those contexts XML is often the standard.
