Re: Reading XML with an RPG program

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

Paul,

There are at least a dozen ways to read XML from RPG.  Different methods 
require different releases and LPPs.

a) Expat is free (open source) and should work on V5R2 with no problems. 
 It requires a little more knowledge/programming.

b) the XML-INTO/XML-SAX RPG opcodes were released in V5R4.  XML-INTO is 
especially easy to use -- but does have limitations, it won't work with 
all docs, and of course it requires V5R4.

c) The IBM XML Toolkit has been around for quite a long time.. I don't 
remember which release it started in.  Frankly, it's really cumberssome 
to use, and all of the examples were written by C programmers (they 
translated their C to RPG -- but it's not the way an RPG programmer 
would write code.  Lots of pointer logic, etc...)  IMHO, it's not a good 
way to get started with XML, it's too complicated.  The XML Toolkit is 
an LPP.

d) There are many, many 3rd party options out there.
