Brief expert note.

Browsers collapse plain whitespace and ignore raw newline characters when rendering HTML, so emitting newlines from XSLT won’t produce visible indentation unless the output is placed into a whitespace‑preserving context. ' suggestion to render the tree inside a preformatted container is the simplest fix; alternatively, a CSS rule that preserves line breaks can be used when wrapping in <pre> is not desirable.

A few practical points not shown in the original thread:

xsl:output indent="yes" affects how the XSLT serializer formats the XML source it writes — it helps when inspecting the generated source but does not force visible indentation in a browser.
If the stylesheet declares the XHTML namespace (default xmlns="http://www.w3.org/1999/xhtml") while using method="xml", the result is namespaced XHTML; how the browser parses that result depends on the MIME type it is served with (application/xhtml+xml vs text/html), which can affect rendering.
Emitting real line breaks from XSLT is most portable using an explicit newline character inside xsl:text, rather than relying on external DTD entities or disable-output-escaping.

Example CSS option (preserves newlines and wraps long lines):

.tree { white-space: pre-wrap; font-family: monospace; }

Quick debugging checklist: inspect the transformed output with View Source to confirm whether <br/> elements or newline characters are actually present; if present but not visible, check CSS rules and container elements; if absent, adjust the XSLT to emit element breaks or newline characters. ’ approach (preformatted output) was confirmed to resolve the original poster’s issue by .

You output html, so using spaces won't have the desired effect, unless you use the <pre> tag. For newlines, you need to add <br/> tags.

What happens if you try another tag, like <hr/> ? Do you see that one in the output ? Perhaps the problem lies elsewhere.

It has to change, perhaps the file is cached ?
