Fix XML invalid syntax

XML must be well-formed: every opening tag must have a closing tag, attributes must be quoted, and special characters escaped.

Common causes

  • Unclosed or mismatched tags.
  • Unquoted attribute values.
  • Invalid characters (<, >, &) in text.

How to fix

  • Match every opening tag with a closing tag.
  • Quote all attribute values.
  • Use &lt;, &gt;, &amp; for special chars. Validate with XML Validator.
