Introduction

DPML is a programming language used to define a sequence of logical NetKernel requests. DPML provides simple sequencing, looping, conditional processing and exception handling and translates each instruction into a single active: request.

Syntax

DPML uses a syntax based on XML. The root element of a DPML program is the XML element idoc and each instruction is identified by the XML element instr. The following skeletal DPML program executes three unspecified instructions in top-to-bottom sequential order:

An optional namespace designation xmlns:dpm="http://1060.org/dpm" may be used. An explicit namespace (dpm: in this example) must be used as the default namespace will interfere with literal parameters.

Executing a DPML Program

DPML programs are executed by the DPML runtime engine accessed with the URI active:dpml. The DPML runtime accepts a single parameter "operand" that refers to the DPML program to be run. For example the DPML program in the resource ffcpl:/src/myprog.idoc is executed with the following request URI:

active:dpml+operand@ffcpl:/myprog.idoc

Passing Paramaters to a DPML Program

Parameters may be passed to a DPML program.
