XML Comment Literal

A literal representing an XComment object.

<!-- content -->

<!--

Required. Denotes the start of the XML comment.

content

Required. Text to appear in the XML comment. Cannot contain a series of two hyphens (--) or end with a hyphen adjacent to the closing tag.

-->

Required. Denotes the end of the XML comment.

XML comment literals do not contain document content; they contain information about the document. The XML comment section ends with the sequence "-->". This implies the following points:

  • You cannot use an embedded expression in an XML comment literal because the embedded expression delimiters are valid XML comment content.

  • XML comment sections cannot be nested, because content cannot contain the value "-->".

You can assign an XML comment literal to a variable, or you can include it in an XML element literal.

NoteNote:

An XML literal can span multiple lines without using line continuation characters. This feature enables you to copy content from an XML document and paste it directly into a Visual Basic program.

The Visual Basic compiler converts the XML comment literal to a call to the XComment constructor.

The following example creates an XML comment that contains the text "This is a comment".

Dim com As XComment = <!-- This is a comment -->
