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

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
