Re: XML-INTO - new to this... -- RPG400-L

To Chris - I don't think you have the issue Peter cites. The use of datasubf is for elements with this form -

<tagname attr="value">text data</tagname>

Note that 'text data' has no name.

You LoginResponse element has another element within it - SessionHandle - this has to be part of your LocalResponse DS. Or you can try the 'allowextra=yes' option.

Here is something from the docs on XML-INTO options -

"If unexpected XML data is found, and 'allowextra=yes' is not specified, the operation will fail with status 00353 (XML does not match RPG variable)."

Hi Chris,

I ran into this problem myself - at the time I was on a v5r4 machine.
Are you on v6r1 yet? See this article:

https://www.ibm.com/developerworks/community/wikis/home?lang=en#/wiki/We13116a562db_467e_bcd4_882013aec57a/page/Two%20new%20options%20for%20XML-INTO%20with%20a%20V6R1%20PTF

(or http://preview.tinyurl.com/xml-into-datasubf-countprefix) which says:

V6R1 PTF SI34938 adds two new %XML options for the XML-INTO operation,
available for programs compiled with TGTRLS(V6R1M0) or greater. To take
advantage of this enhancement, RPG programs will have to be recompiled
with PTF SI34941.

The new options are

* datasubf
* countprefix

The/datasubf/option enables the XML-INTO operation to handle XML
elements in the following form:

<tagname attr="value">text data</tagname>

The/countprefix/option provides a way to detect the number of subfields
and subfield array elements which were set by the XML-INTO operation. It
reduces the need to specify the allowmissing=yes option.

Hello all,

This has me tearing my hair out on a weekend... Boo.

I'm attempting to parse some XML. I'm trying to use the new(er) opcodes as opposed to the old string methods. I thought it was/is the most straightforward you can imagine...

I'm trying to pull the 'true' value out of the LoginResponse attribute.

Here's the XML... (Yes, it's MAPICS)

<?xml version='1.0' encoding='UTF-8'?>
<System-Link version='1.0' hostVersion='1.0'>
<LoginResponse actionSucceeded='true'>
<SessionHandle value='-3369e2f8:1445eea302e:-799f'/>
</LoginResponse>
<Response sessionHandle='-3369e2f8:1445eea302e:-799f' workHandle='-3369e2f8:1445eea302e:-799e' systemTimestamp='2014-02-28 20:54:41.668' systemTimeZoneOffset='-6:00'>
<UpdateResponse name='updateObject_ItemRevision' actionSucceeded='true'/>
</Response>
</System-Link>

Here's my code... (variable "rpns" is my xml)

D* Local fields
D retField S N inz(*off)
D LoginResponse DS qualified
D action...
D Succeeded 10

/FREE

// was the login request successful?
xml-into LoginResponse
%xml(rpns:'path=System-Link/LoginResponse +
case=any doc=string');
if LoginResponse.actionSucceeded='true';
retField = *on;
ENDIF;
I'm getting this error...

The XML document does not match the RPG variable; reason code 1.

Cause . . . . . : While parsing an XML document, the parser found that the
XML document does not correspond to RPG variable loginresponse and the
options do not allow for this. The reason code is 1. The exact subfield for
which the error was detected is loginresponse. The options are
"path=System-Link/LoginResponse case=any doc=string". The XML document name
is *N; *N indicates that the XML document was not an external file.

In the process of trial and error, I've also received reason code 4 and 5.

What am I doing wrong?!? I've messed with the path, the options, the DS. It's making me crazy.

Thank you for your help.
