XML_BADEXCHAR

Unknown character &xxx;

Fanuc · R-30iA R-30iB Controller

What does XML_BADEXCHAR mean?

This fault arises when an unrecognized or invalid XML entity reference (e.g., &xxx;) is encountered in the XML file. Valid entity references are either predefined (e.g., <, &) or declared in a DTD/schema, and unknown ones stop parsing.

Common Causes

  • An XML entity reference (e.g., <) is malformed or uses an unrecognized name.
  • The XML file contains an unknown character encoding reference.
  • A typo in the entity name within the reference.
  • The parser does not recognize the specified character entity.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Replace the unknown entity reference with its corresponding character or a valid entity.

  2. 2

    Ensure all entity references in the XML file are properly defined and formatted (e.g., &name;).

  3. 3

    Verify that the entity names used are standard XML entities or custom entities defined elsewhere.

  4. 4

    Correct any typos in the entity names.

  5. 5

    If custom entities are used, ensure their definitions are accessible to the parser.
