RE: Parsing an XML-XLSX file using XML-INTO

Hi Jon,

I've tried various things without completing success here. I think I'm going to take the simpler route and parse the text, since there are enough consistent markers to do this in the XML. I'll wait for something simpler and smaller to intro the parser.

It's just a huge file, this one, one file went to nearly 112 megabytes, and Notepad++ counted almost 50,000 rows in one file. Many of the Cells have no "<Data>" content, so I presume allowmissing=yes would be required to be able to get past them without the error.

I even decided to go simple and just port your code straight in as is, and parse straight to the Row(..) data structure array instead of using the handler procedure.

But then I got the same error as I started this with, that is, a full count of returned Rows() but all blank data.

The code is at http://code.midrange.com/51fe4e4ae9.html.

Below the signature line are the two messages I got.

Alan



First message I got said it countpfx was not valid for XML-INTO (hunh???)

RNX0352: Option 'countpfx=Count' is not valid for XML-INTO; reason code 2;
Cause . . . . . : An RPG procedure attempted to use an option string
containing option 'countpfx=Count' which is not valid in the context of the
XML-INTO operation. The reason code is 2. The full option string is
"countpfx=Count path=Workbook/Worksheet/Table/Row doc=file datasubf=Data
ns=remove case=any trim=all allowextra=yes".
2. The option is not valid in the context of XML-INTO.

So I took out the countpfx= option and the count fields (except for rowcount in the PSDS).
Next was that there were missing elements in the XML.

RNX0353: The XML document does not match the RPG variable; reason
code 4.
Cause . . . . . : While parsing an XML document, the parser found that the
XML document does not correspond to RPG variable "row" and the options do
not allow for this. The reason code is 4. The exact subfield for which the
error was detected is "row(1).cell(2).data". The options are
"path=Workbook/Worksheet/Table/Row doc=file datasubf=Data ns=remove
case=any trim=all allowextra=yes". The XML document name is
/TESTRDP/DAILY/Daily Deposits-April 2014.xml; *N indicates that the XML
document was not an external file.
4. The XML document is missing XML attributes or elements to match
subfields.

If you have a problem with the path just send me details of the file format you are trying to process - or even better post an example of the XML to the midrange code area.

Thanks millions, Jon!

Thing is, we're on v7r1 but without the TR's that allow for complete free-form (sigh) (for "political" reasons) which I'll be trying to take care of (after this month end the "politics" will change, but we'll see). I "studied" the RPG reference and guide both on XML-INTO to get as far as I did but I'll apply your points.

As to the Excel, I'm not at work yet till later this morning, I'll check the Excel version...

You say the path= is "way too deep". I first tried just doing it from "row" but I'll do that again.

Thanks again,
Alan

Turns out the Excel 2004 XML matched what you had better than I thought. This program works and processes all of the XML document I gave it.

A few points:

1) No allowmissing or allowextra.

allowextra is probably needed - particularly if you don't care about the Type fields. allowmissing was not needed because I supplied a count variable (countprefix) wherever it was needed (rows and cells) which as you will see also simplifies the processing.

By using both you basically guaranteed that any valid XML document would process without error no matter what it contained.

2) ns=remove option needed as namespaces are present and need to be stripped out.

3) datasubf was needed because data and attributes occur together in the <Data> element.

4) your path= went way too deep. You needed to target the first of the repeating elements - which (at least in 2004 Excel XML) appears to me to be row - which is what I would have expected. Because your path was wrong no data was found.

Think that's about it. Except to say that if you are on V5R4 you have a bit of a problem as you are missing a number of needed features. You could live without but it won't work as well. If you need V5R4 let me know.

Here's the code (Free-form 'cos fixed feels like hard work now):

dcl-ds *n PSDS;
RowCount int(20) pos(372);
End-Ds;

dcl-s r int(3);
dcl-s c int(3);

dcl-ds Row Dim(100) Qualified Inz;
Cell LikeDs(Cell_T) Dim(10);
CountCell int(5);
End-Ds;

dcl-ds Cell_T Template Qualified;
Data LikeDs(Data_T);
End-Ds;

dcl-ds Data_T Template;
Type char(20);
CountType int(3);
Data char(40);
End-Ds;

// Much as I hate CtData I couldn't be bothered to copy the XML to the IFS
// so the spreadsheet XML was all dumped at the end of the source
dcl-ds xmlData;
xml Char(80) Dim(200) CTData;
end-ds;

xml-into Row %XML( xmlData: 'countPrefix=Count datasubf=Data +
ns=remove case=any
path=Workbook/Worksheet/Table/Row' );

dsply ( 'Processed ' + %Char(RowCount) + ' Rows' );

For r = 1 to RowCount;
For c = 1 to Row(r).CountCell;
dsply ( 'Row ' + %Char(r) + ' Cell ' + %Char(c) + ' Data =' );
dsply ( Row(r).Cell(c).Data.Data );
EndFor;
EndFor;

Ladies and Gentlemen,



Thanks to all of you that provided suggestions for using the POI classes.



Finally I went the route of asking the users to do the "Save As" XML from an .xlsx file.

Now I'm working on parsing out the data. I could do a search on what I know will be there but decided to try the XML-INTO.



Got it to compile successfully, got it to run as if it was all peachy, but I'm getting solid blank spaces. I mean for example, ROW(1).CELL(1).DATA(1) = *ALL' '. All blanks. And I checked others too, just blanks.

Found a couple of things by trial and error as I expected. One is that the parser wants the whole path, everything, not just the atomic elements. I can't figure out why.



Here's the relevant code for the XML-INTO operation:

Here's the relevant code for the XML-INTO operation:

options = 'path=Workbook/Worksheet/Table/Row/Cell/Data +

doc=file +

case=any +

trim=all +

allowmissing=yes +

allowextra=yes ' ;

//

xml-into %handler( handler : shared )

%XML( %str(pfpath) : options );

(Where pfpath is the pointer to the null-terminated (trimmed) path
of the XML document in the IFS.)



And the handler procedure:

*
--------------------------------------------------------------------

P Handler B export

D Handler pi 10i 0

D share 1024a

D row likeds( rowdata ) dim( 25 )

D const

D rowcount 10u 0 value

*
--------------------------------------------------------------------

* Data structures for Handler parameters and processing

D RowData ds dim( 25 ) based(p_rowdata)

D qualified

D Cell likeds( CellDS ) dim( 30 )

* ------------------

D CellDS ds based(p_CellDS)

D data 100a dim( 5 )

*
--------------------------------------------------------------------



I'm first testing to make sure I'm getting what I should.

So in the code I'm using a short field to use with DSPLY for the first 25 bytes of a couple of elements in the code.



Like this:

msg = %subst( row(xa).cell(xb).data(xc): 1: 20 ) ;

dsply 'data_is' ' ' msg ;



Using xa=1 then 2 etc.

Blanks. Every time blanks.

What did I miss, guys?



I'll look at the responses over the weekend.
