Common XML Syntax Errors & Well-Formed Solutions
Understand how our DOMParser engine inspects well-formed XML tag structures and attribute rules.
| Error Category | Broken XML Code | Valid Repaired Code | Syntax Cause |
|---|---|---|---|
| Unclosed Element Tag | <user><name>Alex</user> | <user><name>Alex</name></user> | Opening tag '<name>' is missing matching closing tag '</name>'. |
| Unquoted Attribute | <item id=101 status=active> | <item id="101" status="active"> | XML attributes must always be enclosed in quotes. |
| Case Sensitivity Error | <Data><Value>42</value></Data> | <Data><Value>42</Value></Data> | XML tags are strictly case-sensitive ('<Value>' vs '</value>'). |
| Unescaped Special Chars | <note>A & B < C</note> | <note>A & B < C</note> | Special characters ('&', '<') must be escaped as entities or in CDATA. |
| Multiple Root Elements | <first/><second/> | <root><first/><second/></root> | A well-formed XML document must have exactly one root element. |

Frequently Asked Questions
About XML Formatter
Everything you need to know about XML formatting, DOM validation, SOAP payload minification, and privacy.
100% Confidentiality
All XML code is parsed and validated locally on your computer. Zero code bytes touch any external server.
Paste your raw XML code or upload an .xml file into the input editor, select your preferred indentation spacing (2 spaces, 4 spaces, or tabs), and click 'Format XML'. Your indented, syntax-highlighted XML will render instantly.
Our validation engine uses the browser's native DOMParser to inspect XML elements, attributes, closing tags, and CDATA blocks. If an unclosed tag or syntax error is found, an alert highlights the exact line and column number.
Yes, 100% private and secure! All XML parsing, DOM validation, indentation, and minification execute entirely inside your browser's local JavaScript memory. Zero code bytes leave your device.
Formatting (beautifying) adds line breaks and indentation spaces (2 or 4 spaces) to make XML human-readable. Minifying removes all unnecessary whitespace between tags to shrink payload file size for production API calls.
Yes! Our parser accurately formats and validates self-closing tags (e.g. <img />), CDATA blocks (<![CDATA[...]]>), comments (<!-- -->), and XML processing declarations.
No! Meema Tools XML Formatter & Validator is 100% free with unlimited document processing, zero file caps, and no user registration required.
