Class SimpleSlopParser

java.lang.Object
  org.apache.cocoon.slop.parsing.SimpleSlopParser

All Implemented Interfaces:

SlopConstants, SlopParser

public class SimpleSlopParser
extends Object
implements SlopParser, SlopConstants

Simplistic SLOP parser, recognizes the following constructs: Field: a line starting with letters and : is considered a field Empty lines are detected. Other lines are output as line elements This is sufficient for basic parsing of RFC 822 headers, but a configurable rfc822 mode would be good to differentiate between the header and body of the email message and parse them with different rules.
