javalangIllegalArgumentException The char 0xb after is not a valid XML character

This exception is thrown when trying to parse or create an XML document, and it encounters an invalid character. In this case, the character '0xb' is not a valid XML character.

In XML, only a certain range of characters are allowed, and any character outside this range is considered invalid. The valid character range in XML is defined by the Unicode specification.

To fix this issue, you need to ensure that all characters in your XML document are within the valid range. You can use a character encoding library to convert any invalid characters to their valid counterparts or remove them altogether.

Here's an example of how you can handle this exception:

try {
    // Your XML parsing or creation code here
} catch (IllegalArgumentException e) {
    System.out.println("Invalid character in XML: " + e.getMessage());
    // Handle the exception, such as replacing or removing the invalid character
}

Remember to always handle exceptions appropriately in your code to prevent unexpected crashes or errors
