What is XSLT Transformer?
An XSLT transformer applies an XSLT stylesheet to an XML document to produce a new output document, typically HTML for display, plain text, or restructured XML. It is the standard way to present and repurpose XML data.
Key Benefits
- Turn raw XML data into readable HTML pages without server processing
- Test and debug stylesheets locally before deploying them to production
- Convert between XML formats for system integrations and reports
- Learn XSLT and XPath interactively with instant feedback
Common Use Cases
- •Rendering RSS or sitemap XML into human-readable pages
- •Converting API XML responses into HTML reports
- •Reshaping configuration or data-export XML between schemas
- •Teaching and learning XSLT template matching and XPath expressions

Frequently Asked Questions
Which XSLT version does this tool support?
It uses the browser native XSLTProcessor, which implements XSLT 1.0 with XPath 1.0. XSLT 2.0 and 3.0 features such as xsl:function and grouping are not supported.
Is my XML data uploaded to a server?
No. The transformation runs entirely in your browser with JavaScript and the built-in XSLTProcessor. Nothing is sent anywhere.
Why is my transform result empty?
The most common cause is a template match expression that does not match the input structure. Check that your match pattern aligns with the root element of your XML document.
What output formats can XSLT produce?
Using the xsl:output method attribute, a stylesheet can produce HTML (method html), plain text (method text), or XML (method xml). This tool detects the method and labels the result.
