Re: how to handle option tag when using CGIDEV2 to create xml data

["Joe Lee" <LeeJD@xxxxxx>]

I mostly just lurk on the list, but...

This type of problem is one of the reasons I created a modified version of CGIDEV2 years ago. I added the ability to have "conditional" sections, basically you have something like this.

/$PaymentInfo
<PaymentInformation>
/?SELECT /%paymentType%/ = "Prepaid"
 <Prepaid>
   <BillShipper>
     <AccountNumber>/%shipperAct#%/</AccountNumber>
    </BillShipper>
  </Prepaid> 
/?WHEN /%paymentType%/ = "BillThirdParty"
 <BillThirdParty>
// blah blah blah   
 </BillThirdParty>
/?WHEN /%paymentType%/ = "FreightCollect"
//etc.....
/?WHEN /%paymentType%/ = "ConsigneeBilled"
//etc....
/?OTHER
?/
</PaymentInformation>


In the wrtSection procedure the conditions are checked and only the valid conditional sections are output. This addition allows a lot more flexibility without having to rewrite/compile/distribute CGI programs. It wasn't too hard to implement. The way I built it the conditional sections are part of a regular sections, and they can be nested. The "/?" "?/" were used to tag the begining and end of the section, and I allowed a condition on the "SELECT" statement as well as on the "WHEN" statements.

Just to clarify my question a bit.

Here is the portion of xsd that I'm dealing:
	<xsd:complexType name="PaymentInformationType">
		<xsd:choice>
			<xsd:element name="Prepaid" type="PrepaidType"
minOccurs="0"/>
			<xsd:element name="BillThirdParty"
type="BillThirdPartyType" minOccurs="0"/>
			<xsd:element name="FreightCollect"
type="FreightCollectType" minOccurs="0"/>
			<xsd:element name="ConsigneeBilled"
type="xsd:string" minOccurs="0"/>
		</xsd:choice>
	</xsd:complexType>

In my RPG program, depending on the shipment method selected on the
order, it will determine which child element to used when creating the
PaymentInformation tag.  My question is how should I create the template
to handle creating above xml using tools in CGIDEV2?

If I create the template as below:
<PaymentInformation>
  /%paymentType%/  ==>  
</PaymentInformation>


I would have to code it like below in RPG (Not pretty):
If order.paymentType = 'PRP';
  updHtmlVar('paymentType' 
            :'<Prepaid>'
                '<BillShipper>' +
                   '<AccountNumber>' + 
                     %trim(shipperAct#) +
                   '</AccountNumber>' + 
                '</BillShipper>' +
            :'</Prepaid>'
. . . 
. . .


wrtSection('myXMLSec');




Note: here is the prepaidType definition:

	<xsd:complexType name="PrepaidType">
		<xsd:sequence>
			<xsd:element name="BillShipper"
type="BillShipperType"/>
		</xsd:sequence>
	</xsd:complexType>
	<xsd:complexType name="BillShipperType">
		<xsd:choice>
			<xsd:element name="AccountNumber"
type="xsd:string" minOccurs="0"/>
			<xsd:element name="CreditCard"
type="CreditCardType" minOccurs="0"/>
		</xsd:choice>
	</xsd:complexType>

How does one normally handle optional xml tag when using CGIDEV2 to
create the xml data?
 
should I do something like below?
 
Template:
/$myXMLSec
  <Order> 
   /%myOptTag%/
  </Order> 



RPG code:
updHtmlVar('myOptTag' :'<MyOptTag>blah blah blah</MyOptTag>'); 
wrtSection('myXMLSec');




Or is there a better way of handling this?

thanks
