XML Minifier

Remove formatting whitespace from parsed XML locally without changing element or attribute values.

ReadyRemoves formatting whitespace from parsed XML. It is not compression such as gzip.

XML structure & handoff review

Parse the document you will actually use

Check structure, namespaces, repeated records, mixed content and remote-looking references. Converter pages review generated XML output when that is the handoff artifact.

Reviewing current XML…

Browser DOM parsing checks well-formedness and structure. It is not an XSD/DTD/business-rule validator, sanitizer or permission to trust remote resources; this review does not fetch external schemas or entities.

XML minification byte budget & whitespace policy

Use the XML already entered above and make payload-size policy explicit. Validate before minifying, choose whether comments are removed, preserve mixed-content text and xml:space="preserve" subtrees, and report exact UTF-8 bytes saved rather than treating minification as generic formatting.

Check	Value	Policy	Evidence

A minifier should reduce transport size without changing mixed-content text. This tool validates first and makes comment/declaration/whitespace policy visible.

What this XML step proves

Minification should remove formatting whitespace without changing meaningful XML text.

What to review before handoff

Mixed content, text-only whitespace, comments, CDATA and processing instructions are preserved while inter-element formatting whitespace is compacted.
