Class: REXML::Instruction

Class | REXML::Instruction
In: | rexml/instruction.rb
Parent: | Child

Represents an XML Instruction; IE, <? … ?> TODO: Add parent arg (3rd arg) to constructor

### Methods

== clone inspect new node_type write

### Constants

START | = | '<\?'
STOP | = | '\?>'

### Attributes

content | [RW] | target is the "name" of the Instruction; IE, the "tag" in <?tag …?> content is everything else.
target | [RW] | target is the "name" of the Instruction; IE, the "tag" in <?tag …?> content is everything else.

### Public Class methods

new(target, content=nil)

Constructs a new Instruction @param target can be one of a number of things. If String, then the target of this instruction is set to this. If an Instruction, then the Instruction is shallowly cloned (target and content are copied). If a Source, then the source is scanned and parsed for an Instruction declaration. @param content Must be either a String, or a Parent. Can only be a Parent if the target argument is a Source. Otherwise, this String is set as the content of this instruction.
