Handling Unbalanced Element Tag Errors in XML

The "Unbalanced Element Tag" error occurs when XML input is not properly formed, meaning an opening tag does not have a matching closing tag. XML requires strict structure; every opening tag must have a corresponding closing tag.

The error originates from the XML class, but it can also appear in higher-level components such as SOAP and REST, which internally rely on XML parsing. To resolve this, ensure that:

• Any XML data you provide is well-formed and properly closed
• Any response received from a service is valid XML before processing it

In most cases, inspecting the input or response payload will reveal the missing or malformed tag causing the issue.
