Re: In-Fo about Larry Ducie XMLi PowerEXT for XML creation -- RPG400-L

Both powerExt and XMLi allow for an API approach to building the XML strings. You basically call the API for each entry you want to output.

In Chapter 5 of the RPG Modernization Redbook (http://www.redbooks.ibm.com/abstracts/sg248185.html <http://www.redbooks.ibm.com/abstracts/sg248185.html>) I wrote an example of using each of these options - including CGIDEV2. So if you look at that you'll get a very direct comparison between the CGIDEV2 approach you are familiar with and the other two options you are considering.

powerext and XMLi are very similar in approach - it is mostly just a question of personal preference. Personally (sorry Henrik) I have a slight preference for XMLi mostly because I find its approach to specifying attributes to be more obvious than the way it is done in powerExt.

Hi all

In this years, i have used CGIDEV2 (as descripted at
www.mcpressonline.com/programming-other/general/play-time-productive-time
<http://www.mcpressonline.com/programming-other/general/play-time-productive
-time> ) for generating Xml with RPG; as i would need to generate XML on
V5R4 or al least at V6R1, i would like to know if with XMLi or PowerEXT i
can solve the problem not to pass/write the empty tags;

Example (using CGIDEV2)

In my template i have:

/$SedeCES

<Sede>

<Indirizzo>/%Indirizzo%/</Indirizzo>

<NumeroCivico>/%NumeroCivico%/</NumeroCivico>

<CAP>/%CAP%/</CAP>

<Comune>/%Comune%/</Comune>

<Provincia>/%Provincia%/</Provincia>

<Nazione>/%Naz%/</Nazione>

</Sede>

When my variable “NumeroCivico” č blank in my Xml i will find:

<Sede>

<Indirizzo>Via del Corso</Indirizzo>

<NumeroCivico></NumeroCivico>

<CAP>00100</CAP>

<Comune>ROMA</Comune>

<Provincia>RM</Provincia>

<Nazione>IT</Nazione>

</Sede>

And clearly this is not good ….as in the <NumeroCivico> there is no value

The simplest way to solve the problem with CGIDEV2 is to change Xml template
like this:

/$SedeCES

<Sede>

<Indirizzo>/%Indirizzo%/</Indirizzo>

/$NumeroCivicoCES

<NumeroCivico>/%NumeroCivico%/</NumeroCivico>

/$SedeCESContinua

<CAP>/%CAP%/</CAP>

<Comune>/%Comune%/</Comune>

<Provincia>/%Provincia%/</Provincia>

<Nazione>/%Naz%/</Nazione>

</Sede>

And add in my RPG :

If NumeroCivico <> *Blank;

WrtSection('NumeroCivicoCES');

Endif

The same thing could be for CAP or Comune and in this way , it would be a
proliferate of IF cond and "WrtSection". It would be nice and helpful to say
not write empty tags in Xml ..

My questione now is:

with XMLi or PowerEXT , can i solve/avoid this problem with more ease ?

Any suggestions will appreciated

Thanks in advance
