Well formed XML document means
-
It contains a root element
-
It contain an element
-
It contains one or more elements
-
Must contain one or more elements and root element must contain all other elements
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) It contains a root element - This option is incorrect because an XML document must have a root element, but it can also have additional elements.
Option B) It contains an element - This option is correct because an XML document must contain at least one element. The element serves as the building block for the XML structure.
Option C) It contains one or more elements - This option is partially correct. An XML document can contain one or more elements, so this statement is true. However, it is not the only requirement for a well-formed XML document.
Option D) Must contain one or more elements and the root element must contain all other elements - This option is incorrect. While an XML document must contain one or more elements, the root element does not necessarily have to contain all other elements. Elements can be nested within other elements to create a hierarchical structure.
The correct answer is B) It contains an element. This option is correct because an XML document must contain at least one element to be considered well-formed.
