Fix steps

  1. 1 Pair each opening tag with the same closing tag.
  2. 2 Close inner elements before parent elements.
  3. 3 Format XML to reveal nesting.

Invalid XML

The name element closes after its parent.

<user><name>Ada</user></name>

Output

Mismatched closing tag

Fixed XML

Close nested elements before closing their parent.

<user><name>Ada</name></user>

Output

Valid XML
