XML Formatter

XML (Extensible Markup Language, a W3C standard) nests elements between matching opening and closing tags, but a minified or single-line document hides that structure. This tool makes the nesting visible by inserting a line break between every adjacent pair of tags (it splits wherever a '>' is immediately followed by a '<') and then indenting each line by two spaces per level of depth. It is a lightweight regex-based reindenter, not a real XML parser: it does not check that your document is well-formed, does not validate against a DTD or XSD, and never reports errors. Depth is tracked by counting opening versus closing tags, with self-closing tags like <br/>, processing instructions like <?xml?>, and comments correctly left at the same level. Inline content such as <name>John</name> stays on one line because the whole line is a single bare element. Because the split keys on the '>' character, a literal '>' inside an attribute value or a multi-line comment can be mis-split and throw off the indentation. For strict validation or schema checks, reach for xmllint or a dedicated XML validator.
