Simple Transformation to deserialize an XML file into ABAP data structures?
I'm attempting to write my first simple transformation to deserialize
an XML file into ABAP data structures and I have a few questions.
My simple transformation contains code like the following
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates"
xmlns:pp="http://www.sap.com/abapxml/types/defined" >
<tt:type name="REPORT" line-type="?">
<tt:node name="COMPANY_ID" type="C" length="10" />
<tt:node name="JOB_ID" type="C" length="20" />
<tt:node name="TYPE_CSV" type="C" length="1" />
<tt:node name="TYPE_XLS" type="C" length="1" />
<tt:node name="TYPE_PDF" type="C" length="1" />
<tt:node name="IS_NEW" type="C" length="1" />
</tt:type>
<tt:root name="ROOT2" type="pp:REPORT" />
<QueryResponse>
<tt:loop ref="ROOT2" name="line">
<QueryResponseRow>
<CompanyID>
<tt:value ref="$line.COMPANY_ID" />
</CompanyID>
<JobID>
<tt:value ref="$line.JOB_ID" />
</JobID>
<ExportTypes>
<tt:loop>
<ExportType>
I don't know what to do here (see item 3, below)
</ExportType>
</tt:loop>
</ExportTypes>
<IsNew>
<tt:value ref="$line.IS_NEW"
map="val(' ') = xml('false'), val('X') = xml('true')" />
</IsNew>
</QueryResponseRow>
</tt:loop>
</QueryResponse>
</tt:loop>
1. In a DTD, an element can be designated as occurring zero or one
time, zero or more times, or one or more times. How do I write the
simple transformation to accommodate these possibilities?
2. In trying to accommodate the "zero or more times" case, I am trying
to use the <tt:loop> instruction. It occurs several layers deep in the
XML hierarchy, but at the top level of the ABAP table. The internal
table has a structure defined in the ABAP program, not in the data
dictionary. In the simple transformation, I used <tt:type> and
<tt:node> to define the structure of the internal table and then
tried to use <tt:loop ref="ROOT2" name="line"> around the subtree that
can occur zero or more times. But every variation I try seems to get
different errors. Can anyone supply a working example of this?
3. Among the fields in the internal table, I've defined three
one-character fields named TYPE_CSV, TYPE_XLS, and TYPE_PDF. In the
XML file, I expect zero to three elements of the form
<ExportType exporttype='csv' />
<ExportType exporttype='xls' />
<ExportType exporttype='pdf' />
I want to set field TYPE_CSV = 'X' if I find an ExportType element
with its exporttype attribute set to 'csv'. I want to set field
TYPE_XLS = 'X' if I find an ExportType element with its exporttype
attribute set to 'xls'. I want to set field TYPE_PDF = 'X' if I find
an ExportType element with its exporttype attribute set to 'pdf'. How
can I do that?
4. For an element that has a value like
<ErrorCode>123</ErrorCode>
in the simple transformation, the sequence
<ErrorCode> <tt:value ref="ROOT1.CODE" /> </ErrorCode>
seems to work just fine.
I have other situations where the XML reads
<IsNew value='true' />
I wanted to write
<IsNew>
<tt:value ref="$line.IS_NEW"
map="val(' ') = xml('false'), val('X') = xml('true')" />
</IsNew>
but I'm afraid that the <tt:value> fails to deal with the fact that in
the XML file the value is being passed as the value of an attribute
(named "value"), rather than the value of the element itself. How do
you handle this?
Try this code below:
data l_xml_table2 type table of xml_line with header line.
W_filename - This is a Path.
if w_filename(02) = '
open dataset w_filename for output in binary mode.
if sy-subrc = 0.
l_xml_table2[] = l_xml_table[].
loop at l_xml_table2.
transfer l_xml_table2 to w_filename.
endloop.
endif.
close dataset w_filename.
else.
call method cl_gui_frontend_services=>gui_download
exporting
bin_filesize = l_xml_size
filename = w_filename
filetype = 'BIN'
changing
data_tab = l_xml_table
exceptions
others = 24.
if sy-subrc <> 0.
message id sy-msgid type sy-msgty number sy-msgno
with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.

Convert XML file into ABAP Query
Hi All,
Can we capture a XML file generated from a Non-SAP system in SAP system and convert into ABAP Query to retreive Data from DB and post it back as a XML query to the same Non-SAP system using a Middleware. Can this process be done in cache memory level itself instead of saving in DB.
If it is possible pls do tell the procedure and steps to be followed.
Suggestion and Help will be much Appreciated
Thanks & Regds.

Issue in Creation of XML file from ABAP data
Hi,
I need to create a XML file, but am not facing some issues in creation of XML file, the in the required format.
The required format is
-<Header1 1st field= u201CValueu201D 2nd field= u201CValueu201D>
- <Header2 1st field= u201CValueu201D 2nd field= u201CValueu201Du2026u2026. Upto 10 fields>

</Header2>

Iu2019m using the call transformation to convert ABAP data to XML file.
So please anybody can help how to define XML structure in transaction XSLT_TOOL.
And one more thing, here I need to put the condition to display the Header 3, Header 4, Header 5 values. If there is no record for a particular line item in header 3, 4 & 5, I donu2019t want to display full line items; this is only for Header 3, 4 & 5.
Please help me in this to get it resolved.Hello,
you can use CALL TRANSFORMATION id, which will create a exact "print" of the ABAP data into the XML.
If you need to change the structure of XML, you can alter your ABAP structure to match the requirements.
Of course you can create your own XSLT but that is not that easy to describe and nobody will do that for you around here. If you would like to start with XSLT, you´d better start the search.

How to upload XML file into the internal table in Webdynpro ABAP ?
Hi Friends,
I am not able to upload the XML file into ABAP,can you please help me in solving this issue with the help of source code.
Regards
DineshHi Dinesh,
Try go through this program which I had developed earlier. It takes as input an XML file and then breaks it down into name-value pairs of an intrnal table. You need to pass an XML file as input to this program. (I had hard coded the path for my XML file in it. You need to replace it with 1 of your own or you can just delete it and use the browse button to selet the file on your PC)

Converting an XML file to a DAT pipe delimited file
Hi
I'm trying to create an SSIS Package which converts an XML file into a dat file which is pipe delimited.
I want the package to be generic so that once that minimal modification is needed when using for different files.
I've so far had no luck with this and need some help/assistance.
All help fully appreciated.
Thank you
Umar JavedThe XML file can vary from fixed to variable.
for Fixed, i've done the same thing as you've suggested and parametrized the flat file connection manager.
For The XML source is there any way we can parametrize the location of the XML or XSD files?
For Variable, unfortunately due to restrictions we can not create an intermediate table and then export.
is there any other way?
Thanks
Umar Javed
XSD path can be made dynamic as below
http://picnicerror.net/development/sql-server/define-xsd-file-for-ssis-xml-source-using-expression-2012-04-21/
For variable you can even add them to configurations and then pass them from a file using xml configuration option.

How do I upload XML files into sap table?
Dear all,
I found some methods that upload xml into SAP,
but there doesnt work under 4.6c.
Can someone tell me how to upload XML files into
sap under 4.6c?
THX!hi,
You can convert XML to abap using transformations. Simple transformations is a proprietary SAP programming language that describes the transformation of ABAP data to XML (serialization) and from XML to ABAP data (deserialization).
goto SE80->workbench->edit object(or other objects)->in object selection chose more tab and then choose the transformation radio button and write a name and click create new.
Here you enter your transformation like
<xsl:transform version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:sap="http://www.sap.com/sapxsl"
>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:transform>
You can use this transfomation in your program using call transformation. You can find more info on call transformation in help.
Hope this helps.

Insert XML file into Relational database model without using XMLTYPE tables
Dear all,
How can I store a known complex XML file into an existing relational database WITHOUT using xmltypes in the database ?
I read the article on DBMS_XMLSTORE. DBMS_XMLSTORE indeed partially bridges the gap between XML and RDBMS to a certain extent, namely for simply structured XML (canonical structure) and simple tables.
However, when the XML structure will become arbitrary and rapidly evolving, surely there must be a way to map XML to a relational model more flexibly.
We work in a java/Oracle10 environment that receives very large XML documents from an independent data management source. These files comply with an XML schema. That is all we know. Still, all these data must be inserted/updated daily in an existing relational model. Quite an assignment isn't it ?
The database does and will not contain XMLTYPES, only plain RDBMS tables.
Are you aware of a framework/product or tool to do what DBMS_XMLSTORE does but with any format of XML file ? If not, I am doomed.
Constraints : Input via XML files defined by third party
Storage : relational database model with hundreds of tables and thousands of existing queries that can not be touched. The model must not be altered.
Target : get this XML into the database on a daily basis via an automated process.
Cheers.
Luc.Luc,
your Doomed !
If you would try something like DBMS_XMLSTORE, you probably would be into serious performance problems in your case, very fast, and it would be very difficult to manage.
If you would use a little bit of XMLType stuff, you would be able to shred the data into the relational model very fast and controlable. Take it from me, I am one of those old geezers like Mr. Tom Kyte way beyond 40 years (still joking). No seriously. I started out as a classical PL/SQL, Forms Guy that switched after two years to become a "DBA 1.0" and Mr Codd and Mr Date were for years my biggest hero's. I have the utmost respect for Mr. Tom Kyte for all his efforts for bringing the concepts manual into the development world. Just to name some off the names that influenced me. But you will have to work with UNSTRUCTURED data (as Mr Date would call it). 80% of the data out there exists off it. Stuff like XMLTABLE and XML VIEWs bridge the gap between that unstructured world and the relational world. It is very doable to drag and drop an XML file into the XMLDB database into a XMLtype table and or for instance via FTP. From that point on it is in the database. From there you could move into relational tables via XMLTABLE methods or XML Views.
You could see the described method as a filtering option so XML can be transformed into relational data. If you don't want any XML in your current database, then create an small Oracle database with XML DB installed (if doable 11.1.0.7 regarding the best performance --> all the new fast optimizer stuff etc). Use that database as a staging area that does all the XML shredding for you into relational components and ship the end result via database links and or materialized views or other probably known methodes into your relational database that isn't allowed to have XMLType.
This way you would keep your realtional Oracle database clean and have the Oracle XML DB staging database do all the filtering and shredding into relational components.
Throwing the XML DB option out off the window beforehand would be like replacing your Mercedes with a bicycle. With both you will be able to travel the distance from Paris to Rome, but it will take you a hell of lot longer.

<rowset>Use XSU to store in multiple tables.
"XSU can only store data in a single table. You can store XML across tables, however, by using the Oracle XSLT processor to transform a document into multiple documents and inserting them separately. You can also define views over multiple tables and perform insertions into the views. If a view is non-updatable (because of complex joins), then you can use INSTEAD OF triggers over the views to perform the inserts."

status_remarks varchar2(100),
segment_number number,
remarks varchar2(100)
before I've created a
create directory test_dir as 'c:\esterno'; -- where I have my acct.xml
and after, can you give me a script for loading data by using XMLTABLE?
I've tried this but it doesn't work:
DECLARE
acct_doc xmltype := xmltype( bfilename('TEST_DIR','acct.xml'), nls_charset_id('AL32UTF8') );
BEGIN
insert into xxrp_acct_details (status_code, status_remarks, segment_number, remarks)
select x1.status_code,
x1.status_remarks,
x2.segment_number,
x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no for ordinality,
status_code number path 'STATUS_CODE',
status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS[$hn]/DETAIL'
passing acct_doc as "d",
x1.header_no as "hn"
columns segment_number number path 'SEGMENT_NUMBER',
remarks varchar2(100) path 'REMARKS'
) x2
END;
This should allow me to get something like this:
select * from xxrp_acct_details;
Statuscode status remarks segement remarks
100 check 2 rp polytechnic
100 check 3 rp polytechnic administration
100 check 4 rp polytechnic finance
100 check 5 rp polytechnic logistics
500 process exception 20 base polytechnic
500 process exception 30
500 process exception 40 base polytechnic finance
500 process exception 50 base polytechnic logistics
but I get:
Error report:
ORA-06550: line 19, column 11:
PL/SQL: ORA-00932: inconsistent datatypes: expected - got NUMBER
ORA-06550: line 4, column 2:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
and if I try to change the script without using the column HEADER_NO to keep track of the header rank inside the document:
DECLARE
acct_doc xmltype := xmltype( bfilename('TEST_DIR','acct.xml'), nls_charset_id('AL32UTF8') );
BEGIN
insert into xxrp_acct_details (status_code, status_remarks, segment_number, remarks)
select x1.status_code,
x1.status_remarks,
x2.segment_number,
x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns status_code number path 'STATUS_CODE',
status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'/ACCOUNT_HEADER_ACK/DETAILS'
passing acct_doc
columns segment_number number path 'SEGMENT_NUMBER',
remarks varchar2(100) path 'REMARKS'
) x2
END;
I get this message:

My oracle version is 10gR2 Express Edition
I do need a script for loading xml files into a table as soon as possible, Give me please a simple example for understanding and that works on 10gR2 Express Edition
Thanks in advance!The reason your first SQL statement
select x1.status_code,
x1.status_remarks,
x2.segment_number,
x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no for ordinality,
status_code number path 'STATUS_CODE',
status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS[$hn]/DETAIL'
passing acct_doc as "d",
x1.header_no as "hn"
columns segment_number number path 'SEGMENT_NUMBER',
remarks varchar2(100) path 'REMARKS'
) x2
returns the error you noticed
PL/SQL: ORA-00932: inconsistent datatypes: expected - got NUMBER
is because Oracle is expecting XML to be passed in. At the moment I forget if it requires a certain format or not, but it is simply expecting the value to be wrapped in simple XML.
Your query actually runs as is on 11.1 as Oracle changed how that functionality worked when 11.1 was released. Your query runs slowly, but it does run.
As you are dealing with groups, is there any way the input XML can be modified to be like
<ACCOUNT_HEADER_ACK>
<ACCOUNT_GROUP>
<HEADER>....</HEADER>
<DETAILS>....</DETAILS>
</ACCOUNT_GROUP>
<ACCOUNT_GROUP>
<HEADER>....</HEADER>
<DETAILS>....</DETAILS>
</ACCOUNT_GROUP>
</ACCOUNT_HEADER_ACK>
so that it is easier to associate a HEADER/DETAILS combination? If so, it would make parsing the XML much easier.
Assuming the answer is no, here is one hack to accomplish your goal
select x1.status_code,
x1.status_remarks,
x3.segment_number,
x3.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no for ordinality,
status_code number path 'STATUS_CODE',
status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS'
passing acct_doc as "d",
columns detail_no for ordinality,
detail_xml xmltype path 'DETAIL'
) x2,
xmltable(
'DETAIL'
passing x2.detail_xml
columns segment_number number path 'SEGMENT_NUMBER',
remarks varchar2(100) path 'REMARKS') x3
WHERE x1.header_no = x2.detail_no;
This follows the approach you started with. Table x1 creates a row for each HEADER node and table x2 creates a row for each DETAILS node. It assumes there is always a one and only one association between the two. I use table x3, which is joined to x2, to parse the many DETAIL nodes. The WHERE clause then joins each header row to the corresponding details row and produces the eight rows you are seeking.
There is another approach that I know of, and that would be using XQuery within the XMLTable. It should require using only one XMLTable but I would have to spend some time coming up with that solution and I can't recall whether restrictions exist in 10gR2 Express Edition compared to what can run in 10.2 Enterprise Edition for XQuery. -
"PLS-00172: string literal too long" When Writing XML file into a Table
Hi.
I'm using DBMS_XMLStore to get a XML file into a db table. See the example below, I'm using that for my PL/SQL format. Problem is that because there're too many XML elements that I use in "xmldoc CLOB:= ...", I get "PLS-00172: string literal too long" error.
Can someone suggest a workaround?
THANKS!!!
DECLARE
insCtx DBMS_XMLStore.ctxType;
rows NUMBER;
xmldoc CLOB :=
'<ROWSET>
<ROW num="1">
<EMPNO>7369</EMPNO>
<SAL>1800</SAL>
<HIREDATE>27-AUG-1996</HIREDATE>
</ROW>
<ROW>
<EMPNO>2290</EMPNO>
<SAL>2000</SAL>
<HIREDATE>31-DEC-1992</HIREDATE>
</ROW>
</ROWSET>';
BEGIN
insCtx := DBMS_XMLStore.newContext('scott.emp'); -- get saved context
DBMS_XMLStore.clearUpdateColumnList(insCtx); -- clear the update settings
-- set the columns to be updated as a list of values
DBMS_XMLStore.setUpdateColumn(insCtx,'EMPNO');
DBMS_XMLStore.setUpdateColumn(insCtx,'SAL');
DBMS_XMLStore.setUpdatecolumn(insCtx,'HIREDATE');
-- Now insert the doc.
-- This will only insert into EMPNO, SAL and HIREDATE columns
rows := DBMS_XMLStore.insertXML(insCtx, xmlDoc);
-- Close the context
DBMS_XMLStore.closeContext(insCtx);
END;
/You ask where am getting the XML doc. Well, am not
getting the doc itself.I either don't understand or I disagree. In your sample code, you're certainly creating an XML document-- your local variable "xmldoc" is an XML document.
DBMS_XMLSTORE package needs
to know the canonical format and that's what I
hardcoded. Again, I either don't understand or I disagree... DBMS_XMLStore more or less assumes the format of the XML document itself-- there's a ROWSET tag, a ROW tag, and a then whatever column tags you'd like. You can override what tag identifies a row, but the rest is pretty much assumed. Your calls to setUpdateColumn identifies what subset of column tags in the XML document you're interested in.
Later in code I use
DBMS_XMLStore.setUpdateColumn to specify which
columns are to be inserted.Agreed.
xmldoc CLOB :=
'<ROWSET>
<ROW num="1">
<KEY_OLD> Smoker </KEY_OLD>
<KEY_NEW> 3 </KEY_NEW>
<TRANSFORM> Specified </TRANSFORM>
<KEY_OLD> Smoker </KEY_OLD>
<VALUEOLD> -1 </VALUEOLD>
EW> -1 </VALUENEW>
<DESCRIPTION> NA </DESCRIPTION>
</ROW>
ROWSET>';This is your XML document. You almost certainly want to be reading this from the file system and/or have it passed in from another procedure. If you hard-code the XML document, you're limited to a 32k string literal, which is almost certainly causing the error you were reporting initially.
As am writing this I'm realizing that I'm doing this
wrong, because I do need to read the XML file from
the filesystem (but insert the columns
selectively)...What I need to come up with is a proc
that would grab the XML file and do inserts into a
relational table. The XML file will change in the
future and that means that all my 'canonical format'
code will be broken. How do I deal with anticipated
change? Do I need to define/create an XML schema in
10g if am just inserting into one relat. table from
one XML file?What does "The XML file will change in the future" mean? Are you saying that the structure of the XML document will change? Or that the data in the XML document would change? Your code should only need to change if the structure of the document changes, which should be exceptionally uncommon and would only be an issue if you're adding another column that you want to work with, which would necessitate code changes.
I found an article where the issue of changing XML
file is dealt by using a XSL file (that's where I'd
define the 'canonical format'), but am having a
problem with creating one, because the source XML is
screwed up in terms of the format:
it's not <x> blah </x>
<x2> blah </x2>
x2="blah" x3="blah> ...etc
Can you point me in the right direction, please?You can certainly use something like the DBMS_XSLProcessor package to transform whatever XML document you have into an XML document in an appropriate format for the XMLStore package and pass that transformed XML document into something like your sample procedure rather than defining the xmldoc local variable with a hard-coded document. Of course, you'd need to write appropriate XSL code to do the actual transform.

1. Is there a way to import large XML files into HANA efficiently?
2. Will it process it node by node or the entire file at a time?
3. Are there any data services provided to do this?
This for a project use case i also have an requirement to process bulk XML files, suggest me to accomplish this taskHi Patrick,
I am addressing the similar issue. "Getting data from huge XMLs into Hana."
Using Odata services can we handle huge data (i.e create schema/load into Hana) On-the-fly ?
In my scenario,
I get a folder of different complex XML files which are to be loaded into Hana database.
Then I gotta transform & cleanse the data.
Can I use oData services to transform and cleanse the data ?
If so, how can I create oData services dynamically ?
Any help is highly appreciated.
Thank you.

Upload an XML file into the Internal table
Hi Guys,
I want to know, how to upload an xml file into the Internal table through ABAP programmingyou just wanted to load the xml file into internal table (as a table of binary strings)or load the xml data mapped to itab row columns
for the first one you can simply use gui_upload
and for the second one you need to load the xml file using gui_upload and use XLST program to transform into an itab
