XML minification removes the whitespace between elements plus optional comments, leaving a valid document that any parser reads identically. Because XML is verbose by design — every element has a closing tag — indentation can account for a surprising share of file size, and sitemaps, RSS feeds and SOAP envelopes often shrink by a third. The one caution is mixed content: whitespace inside a text node can be meaningful, so this minifier collapses whitespace between tags but does not touch the inside of text nodes, which keeps titles and descriptions intact. Everything runs locally, so internal API envelopes stay private.
