Re: XML-INTO and self-closing tags

I ran a version of your code and the job log shows that the error was RPG status 105 - which means
Invalid characters in character to numeric conversion functions.

So the parser is returning a value that cannot be converted to a number. In this case the parser is retuning a space and %Dec (which is effectively being used under the covers) cannot convert blanks to zero. IBM have been asked to change this but for now we are stuck with it.

Had you looked at %Status - which you should always do when you code the (E) extender - you would have seen the error.

Hello,
I am successfully using xml-into in many applications, but sometimes the
XML answer of a web service is like this:

<?xml version="1.0" encoding="utf-8"?>
<InfoLabel>
<Parcel>
<SiglaMittente>E3</SiglaMittente>
<NumeroSpedizione>800000009</NumeroSpedizione>
<TotaleColli>11</TotaleColli>
<TipoCollo />
<SiglaSedeDestino />
<DenominazioneMittente>GLS BOLOGNA</DenominazioneMittente>
<DenominazioneDestinatario>PROVA ETICHETTE</DenominazioneDestinatario>
<IndirizzoDestinatario>VIA DEL FONDITORE 2/7</IndirizzoDestinatario>
<CittaDestinatario>MILANO</CittaDestinatario>
<ProvinciaDestinatario>MI</ProvinciaDestinatario>
<DataSpedizione>03/03/20</DataSpedizione>
<DescrizioneSedeDestino>GLS Check</DescrizioneSedeDestino>
...other xml data..
</Parcel>
<Parcel>
...other xml data..
</Parcel>
</InfoLabel>

where the difference is the presence of self-closing tags (likeTipoCollo in
the example). Other web services usually return both opening and closing
tags with a blank inside.

When xml-into is executed it breaks with this error:
RNX0353 - The XML document does not match the RPG variable; reason code 8.
where
8. The XML document contains data that cannot be successfully assigned to
the RPG variable. The RPG status code associated with the failure is 105. The
exact subfield for which the error was detected is
"infolabel.parcel(1).tipocollo"

The data structure is defined like this:
dcl-ds DsInfoLabel qualified inz;
SiglaMittente char(2) inz;
NumeroSpedizione zoned(9: 0) inz;
TotaleColli zoned(2: 0) inz;
TipoCollo zoned(1: 0) inz;
SiglaSedeDestino char(4) inz;
... other fields...
end-ds;
dcl-ds InfoLabel qualified inz;
NumParcel int(10) inz;
Parcel likeds(DsInfoLabel) dim(99);
end-ds;

This is the operation code:
xml-into(e) InfoLabel %xml(resmsg_DATA: xmlopts);
where
xmlopts='doc=string trim=all case=any allowmissing=yes allowextra=yes
path=InfoLabel countprefix=Num'

As far as I know, there isn't any other option that can be set to avoid
this situation.
Also, this web service must be used as-is.
Is there something else I can do??

Thank you
