*Requires JavaScript 1.6 or higher*

Syntax: `mutilineString(_ processing instruction_)`

**Note**: The string processing instruction cannot include ?> in the string and does not support escaped characters (ie. \u0000)

Example:

var string =
LEFT-ANGLE-BRACKET?string foo
bar
baz?RIGHT-ANGLE-BRACKET;
mutilineString(string) == "foo\nbar\nbaz"

Due to a problem with Snipplr, I can't put processing instructions in the comments. Replace LEFT-ANGLE-BRACKET with < and replace RIGHT-ANGLE-BRACKET with >

if (this.XML && XML.ignoreProcessingInstructions == true)
    XML.ignoreProcessingInstructions = false;
 
function multilineString(spi) { // spi === <?string ...?>
    if (typeof spi != "xml")
        throw new TypeError(arguments.callee.name);
    return spi.toXMLString()
      .replace(/^<\?string ([\s\S]*)\?>$/i, "$1")
}
