2. In the XML parser processing model, the parser should not stop processing even if the data is not well- formed

A) True
B) False

Answer :- B) False

In the XML parsing processing model, if the data is not well-formed (i.e., it doesn't adhere to the syntax rules of XML), the parser will usually encounter an error and stop processing. Well-formedness is a fundamental requirement for XML documents, and parsers are designed to enforce this rule. If the data is not well-formed, the parser cannot continue processing because it cannot interpret the content correctly.

So, if the data is not well-formed, the XML parser will indeed stop processing and report an error.
