XML-INTO can extract the data you are looking for, but here is the
difference in building
DS that mimic the XML document with XML-INTO and the sequential processing
method
that doesn't require any DS in either XML-SAX and my xmlReader ...

xmlFromStmf('/xmltest2.xml');
xmlReaderInz(xmlAddr:xmlSize);
xmlReaderCase('M');

dow xmlReader = 0;

select;
when xmlGetNode = 'LoginResponse' and xmlGetAttr='actionSucceeded';
dsp = xmlGetData;
dsply dsp;
when xmlGetNode = 'SessionHandle' and xmlGetAttr='value';
dsp = xmlGetData;
dsply dsp;

endsl;

enddo;

The result is

DSPLY true
DSPLY -3369e2f8:1445eea302e:-799f

I have to say, the thing that was crazy-making about this... I really
thought I had tried allowextra and allowmissing.

That is, I thought I had exhausted all permutations of the path,
allowextra and allowmissing options along with the construction/naming of
the data structure. And I had looked all over Google for examples. Most
of the examples I found were using very straightforward XML and therefore,
not extremely helpful. Also, the DS situation becomes confusing in a hurry
to me.

Anyway, I was able to get my stuff working. :) I really appreciate
everyone taking the time to post some thoughts. It was really a life-saver.

Thank you!

AH - have to leave something as an exercise for the reader!

I actually think it was enough to mention the allowextra, as I did in my
first post - - that's all that was needed to make Chris' code work
correctly.

Sounds good, Chris.

As I read it, if you don't use the allowextra, you have to make your
DS account for every element or attribute from the nodes the path
defines and down. And if you have that "text-data" situation, you
need the 6.1 PTF - but not for your situation, fortunately.

Henrik sent some nice examples of what should work for you - seems
he already tried them out!! It must be a dull day in Denmark!

I think trying both approaches is a good learning experience, as you
say
- this thing has taken a bit of practice, even for the limited use
I've made of it and the simple XML I've had to work with.

Cheers
Vern

Thanks! I'm going to try this. I assumed that if it found the
data I
specified, it would just load the DS and finish without having to go
further into the nesting.
XML totally makes sense to me, but the surrounding jargon is
confusing
to an "only-occasionally" programmer like myself.
I'll try allowextra. ...or build more DS to get the sessionhandle
field. It'll be a learning experience.
To Peter...
Thank you!
We *are* at V6R1. Is that PTF more recent? I think we're up-to-date.

Thank you so much for taking the time to respond! I'm very grateful!

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#/w
iki/
We13116a562db_467e_bcd4_882013aec57a/page/Two%20new%20options%20fo
r%20
XML-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.

Christopher Wyatt
