5.5 Processing Instruction Nodes

There is a processing instruction node for every processing instruction, except for any processing instruction that occurs within the document type declaration.

A processing instruction has an [expanded-name] : the local part is the processing instruction's target; the namespace URI is null. The [string-value] of a processing instruction node is the part of the processing instruction following the target and any whitespace. It does not include the terminating ?>.

NOTE: 

The XML declaration is not a processing instruction. Therefore, there is no processing instruction node corresponding to the XML declaration.
