What is XML XSL Transformation?

XSLT (Extensible Stylesheet Language Transformations) is a language for transforming XML documents into other formats. This tool uses the browser's built-in XSLTProcessor to apply your XSLT 1.0 stylesheet to an XML input and display the result. Common uses include transforming XML data feeds into HTML tables, converting XML schemas, or restructuring XML for different consumers.

How to Use XML XSL Transformation

1

Paste your XML document into the XML input panel.

2

Paste your XSLT stylesheet into the XSL input panel.

3

Click Transform (or it transforms automatically).

4

View the result — HTML output shows a live preview.

5

Copy or download the transformed output.

Common Use Cases

  • Transforming an XML data feed into an HTML table for display.
  • Converting XML from one schema to another using XSLT templates.
  • Extracting specific data from XML using XPath expressions in XSLT.
  • Testing XSLT stylesheets before deploying to a server-side pipeline.

Example Input and Output

An XSLT stylesheet transforms a book catalog XML into an HTML table.

XML + XSLT
<catalog><book><title>Clean Code</title></book></catalog>
Transformed HTML
<html><body><table>...</table></body></html>

Note

For XSLT 2.0/3.0 features (such as grouping, sequences, or regular expressions), you need a server-side processor like Saxon or Xalan.

Frequently Asked Questions

What XSLT version is supported?
The browser XSLTProcessor supports XSLT 1.0. XSLT 2.0 and 3.0 features are not available in the browser engine.
Why does my HTML output have xmlns attributes?
The XML serializer sometimes adds namespace declarations. The tool strips common xmlns artifacts for cleaner HTML output.
Is my XML sent to a server?
No. The transformation runs entirely in your browser using the native XSLTProcessor API.
