SEO: target striking-distance keywords + strengthen landing pages and blog
Phase 1 (home): add explicit "viewer", "validate xslt online" and "xslt transformation online" coverage in copy, meta keywords, a new section and a FAQ entry (+ JSON-LD) to lift queries stuck at position 8-10. Phase 2 (landing pages): add unique runnable examples with input/output (for-each-group on /xslt-2-0/, maps + fold-left on /xslt-3-0/) plus internal links to related blog posts and pre/code styling. Phase 3 (blog): xsl-online-tester gets links to both version landing pages, a FAQ block and related guides; xslt-string-functions gets a snippet-bait summary table and related links. Adds scripts/seo_report.py to pull GSC + GA4 metrics for tracking progress. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

<h2>XSLT Viewer, Validator and Transformation Tool</h2>
|
||||
<p>
|
||||
XSLT Playground works as an <strong>online XSLT viewer</strong>: paste a stylesheet and an XML
|
||||
document to view the formatted transformation output, with syntax highlighting and a live HTML
|
||||
preview when your stylesheet uses <code>method="html"</code>. It is also a full
|
||||
<strong>XSLT validator</strong> — invalid stylesheets are flagged with the exact line number and
|
||||
the original Saxon error message, so you can validate XSLT online before deploying it to production.
|
||||
</p>
|
||||
<p>
|
||||
Every <strong>XSLT transformation online</strong> runs against a real Saxon backend in
|
||||
milliseconds. There is nothing to install and nothing to configure: open the editor, paste your
|
||||
code, and the result appears automatically as you type.

If you already know which version you need, there are dedicated testers: the [XSLT 2.0 online tester](https://xsltplayground.com/xslt-2-0/) for grouping and regular expressions, and the [XSLT 3.0 online tester](https://xsltplayground.com/xslt-3-0/) for maps, arrays and streaming. Both run the same Saxon HE backend.

|

|

## Frequently asked questions
|
||||
|
||||
**Is there a free XSL online tester?**
|
||||
Yes. [XSLT Playground](https://xsltplayground.com) is a completely free online XSL tester. It runs XSLT 1.0, 2.0 and 3.0 on a real Saxon HE backend, with no account, signup or installation required.
|
||||
|
||||
**Can I run XSL transformations in the browser?**
|
||||
The editor runs in your browser, but the transformation itself executes on a Saxon server so the results match production exactly — unlike the browser's built-in XSLT 1.0 engine, which is limited and inconsistent across browsers.
|
||||
|
||||
**What is the difference between .xsl and .xslt files?**
|
||||
Both extensions are valid and interchangeable. `.xsl` is older and common in enterprise systems; `.xslt` is more explicit. Saxon and XSLT Playground accept either.
|
||||
|
||||
**Can I validate an XSL stylesheet online?**
|
||||
Yes. If your stylesheet is malformed or has a runtime error, the [XSLT validator](https://blog.xsltplayground.com/posts/xslt-validator-online/) reports the exact line number and the original Saxon error message so you can fix it before deploying.

String manipulation is one of the most common tasks in XSLT. Whether you are formatting output, parsing codes, or normalising values from external systems, XPath provides a rich set of string functions. This reference covers the most useful ones with examples you can run in [XSLT Playground](https://xsltplayground.com).
