Which of the following is an example of using the XmlWriter class correctly?

1. Creating an XML document without indentation

2. Writing an XML document with attributes

3. Reading XML documents from a file

4. Generating JSON from XML data

The correct answer is: Writing an XML document with attributes

Using the XmlWriter class correctly involves creating XML documents and specifically, writing XML elements, which can include attributes. The XmlWriter class is designed for writing XML data in a fast, forward-only manner. When utilizing this class, one of its primary features is the ability to add attributes to elements. For example, when creating an XML element, you can specify attributes to provide additional information about the element, such as properties or metadata. The ability to write XML documents with attributes aligns perfectly with how XmlWriter functions. When an XML element is created, attributes can be added by invoking methods specifically designed for this purpose. This makes it easy to construct well-formed XML documents that adhere to the XML standard. The other options do not align with the primary role of the XmlWriter class. While creating an XML document without indentation could be technically possible, it doesn’t demonstrate the functionality of the XmlWriter in presenting structured data. Reading XML documents from a file typically involves using classes like XmlReader rather than XmlWriter, which is primarily for writing. Generating JSON from XML data is an entirely different functionality and outside the scope of what XmlWriter is designed to accomplish. Thus, writing an XML document with attributes exemplifies the correct and intended use of the XmlWriter
