BSP Element Expressions XML Parameters : ABAP Question
Hi, can anyone please give me a tip or a small example of a use of parameters in XML BEE? They are defined in a BSP and then set there in the bee SET method of CL_BSP_BEE_XML. Brian McKellar gives an example in his Weblog /people/brian.mckellar/blog/2003/10/30/bsp-programming-bsp-element-expressions-bees but I have a different situation and dont understand what they might mean for me. Thanks for any information. Best regards David Lawn
This post has now been answered in the BSP forum.

Hi Brian, thank you very much.
In fact I have success with the tutorials you have given. I still have some difficulties but believe they can be overcome:
1. I am in a method of the bsp application class. I have dumped the code into this method from a bsp page include fragment.
2. Thus, in this method, I now have business logic abap determining which <htmlb elements are created and what values the variables of these elements have. Thus at runtime I pass to the bee a concatenated string like '<htmlb:textView id ="' l_id_element_name ' text = "' l_text 'design = "' l_design '"' ... '/>'. I had figured I had, at runtime, no variables and so needed no parameters. In fact, I have had to find that if I do not code parameters then adding in a second piece of <htmlb code crashes the bee and I loose the browser display of the first one. If I parameterise the first and the second, then I have both. So thats clear. I have also found that bee string syntax is totally strict. I also looked at bee->m_dom dom_table in the debugger, together with the parameters, which helped me understand.
I am adding in bits of the huge amount of business logic at a time to keep the bee string consistent.
3. After setting the bee I pass it back to the view include that called my method (I have a nice ddic structure for that) and display the result as you do in your tutorial.
4. The total result thus is that I no longer need business logic in my view includes and can create html from htmlb in the application class method, which is what I need. Thanks!
4. My need: I firstly just need to get a form onto the browser as quickly as possible so that other project members can see it and plan. Performance is secondary at the moment. I am happy to use the xml bee.
5. The bsp I work with has a strange structure, with a page with flow logic <bsp:goto-ing a controller which calls a view with many includes, one of which is mine (which also has includes). So your other suggestion, using views, will also be followed up as soon as I get my page up and visible.
Kind regards David -
BSP Programming: BSP Element Expressions (BEEs)
Hi,
Alex reported a difficulty with
BSP Programming: BSP Element Expressions (BEEs)
/people/brian.mckellar/blog/2003/10/30/bsp-programming-bsp-element-expressions-bees
back in March.
Since I also set up the example contained in that paper recently, and since I permitted myself to add in some lines of code with which it works well, I give those lines here:
1) the bee call:
<%
if bee is bound.
%>
<bsp:bee bee="<%= bee %>" />
<%
endif.
%>
2) in the xml part of onInputProcessing:
2.1)
data: xml_errors type TIXMLTERR.
2.2)
append <xml_parm> to xml_parms.
also seemed a good idea.
I hope this is useful.
Best regards
David LawnOops ... I dont need the append statement of course (because I have insert .. assigning). Sorry about that.

Hi Forums,
What is the use of BEE and where do we use it ? can any body explain with the help of example.
Documents with example will really helpful.
Thanks in advance.

Hi,
I am practicing on BSP Element Expressions and i have gone through the weblog by Brain McKellar. I am trying the same example given in the weblog but i am getting an exception at the statement
<bsp:bee bee = "<%= bee%>" /> in the layout.
I have not instantiated but i have declared it as an page attribute as given in the weblog.
Why am i getting an error? any help is highly appriciated.
Regards,
Azaz.You have to instantiate the bee before you use it. otherwise the bee is not bound or is null so u'll get exception. The right way is to check the bee before you use it i.e.
change the html layout code this way.
<% if bee is bound. %>
<bsp:bee bee = "<%= bee%>" />
<% endif. %>
This is the first step. This way even if you don't instantiate the bee, u'll not get any exception or crash.
Second point is using the bee if instantiated properly.
Instantiation of bee is compulsory if you want to use it.
Do the instantiation anywhere where u think its correct. you can do it in OnInitialization handler or in inputProcessing etc. In the blog it is done in the OnInputProcessing.
As I said earlier, the fixes to make that code work properly are mentioned at the bottom of the blog.

Xml to abap internal table by using a dynamic internal table at runtime
Hi ,
I have a requirement to convert xml to abap internal table . But the requirement is that i need to create internal table according to the XML .
Ex : If my XML is :
<?xml version="1.0" ?>
- <flights>
- <airline code="AA" name="American Airlines">
- <flight number="0017">
<from airport="JFK">NEW YORK,US</from>
<to airport="SFO">SAN FRANCISCO,US</to>
<departure>110000</departure>
<arrival>140100</arrival>
<type>Scheduled</type>
</flight>
- <flight number="0064">
<from airport="SFO">SAN FRANCISCO,US</from>
<to airport="JFK">NEW YORK,US</to>
<departure>090000</departure>
<arrival>172100</arrival>
<type>Scheduled</type>
</flight>
</airline>
So after conversion my abap internal table shoul have fields as :
airline_code Name flight_number from_airport to_airport departure arrival type
and the field values should be corresponding field values .
Thanks in advance .
Regards .Hi Ujjwal,
use
CALL TRANSFORMATION
Study the online documentation and if required do some search for CALL TRANSFORMATION and/or XML PARSER
And, when coming back here with next question, tell us what searches you did with what results - please always follow the 'search before post' rule, thank you.

To convert XML to ABAP internal table can we do it with DOM or we need XSLT
I have a requirement where I need to collect the data from XML file into an internal table.
I need to collect this data into an internal table as I should make use of this data and do Goods Receipt in SAP.
My XML file is very very complex and the child nodes in my XML file may occur ones or 10 times and change dynamically.
I want to know if XML to ABAP internal table is possible with DOM or does it need XSLT too.
I used the blog of Robert which uses DOM, but it I am unable to collect the data in internal table. The blog explains only how to wtite the out put to screen as element and value.
I want to know if XML to ABAP internal table is possible with DOM or do I need XSLT too? I am confused please help.
Any help will be highly appreciated.

Jessica SamHello Jessica
Why not using the DOM itself for processing?
Below you see the post-processing coding which I use to add the interchange control number (ICN) into an EDI message (which at this stage is still an XML-EDI stream). This is done on SAP-XI yet on the ABAP stack so you could use this approach on your R/3 system as well.

In your case you would need to do a DO...ENDDO loop until you parsed all required nodes.

Hello friends,
I am trying a ABAP program (posted on SDN) to convert XML into ABAP (internal table) and not having any luck. Either it is my table/structure declaration or XSLT. Could any of you experts give me a hand with it please?
Thanks in advance..but points on help!
Here is my XML:
And my ABAP program:
REPORT ZTESTXMLREAD.
TYPE-POOLS: abap, ixml.
class cl_ixml definition load.
TYPES: BEGIN OF t_dc40,
docnum(17) TYPE C,
status(2) TYPE C,
END OF t_dc40.
TYPES: BEGIN OF t_emkt,
spras(2) TYPE C,
maktx(35) TYPE C,
END OF t_emkt.
TYPES: BEGIN OF t_emrm,
matnr(12) TYPE C,
ersda(8) TYPE C,
ernam(25) TYPE C,
emktx TYPE t_emkt,
END OF t_emrm.
TYPES: BEGIN OF t_mm,
dc40 TYPE t_dc40,
emrm TYPE t_emrm,
END OF t_mm.
DATA: l_ixml TYPE REF TO if_ixml,
l_streamfactory TYPE REF TO if_ixml_stream_factory,
l_istream TYPE REF TO if_ixml_istream.
DATA: l_filename TYPE string.
DATA: it_airplus TYPE STANDARD TABLE OF t_mm,
wa_airplus TYPE t_mm.
*Errorvariables
DATA: xslt_err TYPE REF TO cx_xslt_exception,
err_string TYPE string.
PARAMETERS: pa_file TYPE char1024 DEFAULT 'c:Test.XML'.
START-OF-SELECTION.
Creating the main iXML factory
l_ixml = cl_ixml=>create( ).
Creating a stream factory
l_streamfactory = l_ixml->create_stream_factory( ).
Creating input stream
l_istream = l_streamfactory->create_istream_uri( 'file://c:Test.xml' ).
here we use the CALL TRANSFORMATION method which calls
TRY.
CALL TRANSFORMATION ZTestXSLT
SOURCE xml l_istream
RESULT xml_output = it_airplus
catch any error, very helpful if the XSLT isn't correct
CATCH cx_xslt_exception INTO xslt_err.
err_string = xslt_err->get_text( ).
WRITE: / 'Transformation error: ', err_string.
EXIT.
ENDTRY.
setting a breakpoint to watch the workarea
by the internal table "it_airplus"
break-point.
LOOP AT it_airplus INTO wa_airplus.
ENDLOOP.Thank you Durairaj, as a matter of fact my program is based on your post (one that you pointed me to). For whatever reason I'm not having luck figuring it out (may be just a bit of work pressure) could you please hlep me a bit more by pointing me to where in my program code/xslt I'm going wrong? I somehow feel that it could be my table structure or xslt.
I would really appreciate it!
Thanks again,

When calling transformerInstance.transform() the XSLT processor performs the identity transformation - it just copies elements, attributes, content, processing instructions and comments to the result stream.
If you're using an xsl file for your transformation already, simply add <xsl:output doctype-system="yourDTDfile.dtd"/> to your existing XSL file.
If you're only using the identity transformation you'd need to change the line of code where you obtain the transformer instance from the TransformerFactory to:
t_factory.newTransformer(new StreamSource("test.xsl"));
and use this as test.xsl:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output doctype-system="yourDTDfile.dtd"/>
<!-- this is the identity transformation -->
<xsl:template match="*|@*|comment()|processing-instruction()|text()">
<xsl:copy>
<xsl:apply-templates select="*|@*|comment()|processing-instruction()|text()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>Good luck. -
Hi Experts, I need help with this XSLT for call transformation. I have defined an internal table and intend to use it as a source for Call Tranformation. But I have Problems to defining my internal table to get the resut of the function transformation.(SAP 4.7)
In my case i have a xml with attibutes and i can't store these attibutes in internal table.
Hope to hear from any of u soon!

i'm wonder if is it possible to get attribute from xml with abap function transformation...
Hope to hear from any of u soon!Hi Marcelo,
Thanks a lot for your reply, your code is very usefull but my problem is located around the XSLT file.
With my progam (abap), I can't read the attibutes from a XML file correctly because the XSLT have not the suitable tags.
In my XML i have 2 rows of "Univers" and after use the function transformation from abap i can store only 1 rows in internal table :
<Catalog>
<EnTete>
<Emetteur>UBB</Emetteur>
<b><Univers libelle="Nettoyage, hygine et entretien" objref="08">
</Univers>
<Univers libelle="Nettoyage, hygine et entretien" objref="09">
</Univers></b>
</EnTete>
</Catalog>
XSLT :
<xsl:for-each select="EnTete">
<ENTETE>
<EMETTEUR>
<xsl:value-of select="Emetteur"/>
</EMETTEUR>
<xsl:for-each select="Univers">
<UNIVERS>
<UNIVERS1>
<LIBELLE> <xsl:value-of select="@libelle"/></LIBELLE>
<OBJREF> <xsl:value-of select="@objref"/> </OBJREF>
</UNIVERS1>
</UNIVERS>
</xsl:for-each>
</ENTETE>
</xsl:for-each>
My question is : How can i do to define attributes in XSLT to allow read them by a program abap ?
In my example, the program abap get only 1 attribute in my iternal table, what is the suitable syntax in the xslt to read all the attributes ?
Hope to hear from any of u soon!

Optional attributes in XML to ABAP transformation
Hi,
I have to deserialize (transformation xml to abap) an xml input file.
I want to use SAP ST (Simple Transformations).
This xml format is using attributes
Such attributes can be transformed in ST with
<tt:attribute name="item_id" value-ref="MATNR"/>
I realized 2 problems:
1. If the xml file does not contain every attribute which is in the transformation.
This can be solved by tt:cond
Sample
<tt:cond>
<tt:attribute name="uom" value-ref="BASE_UOM"/>
</tt:cond>
Now attribute uom is optional. Without the tt:cond the ST prragrom would throw exception if it is not in the file.
2. If the xml file contains an attribute which is not used in the transformation.
I tried to use tt:skip but it is not working for "<tt:attribute name= ... value-ref=... name" but only for "<tt:value-ref=...".
I only want to get the values I need out of the parameter list.
How can I achieve this without defining a transformation for every parameter in the xml file?
Thanks and regards
MichaelHi,
thanks for reply. It took me into the right direction. You have to distinguish between elements (ordered structured nodes) and attributes (unordered structured nodes). In my case they are using attributes for the values of a material master.
Here is a snippet (sample of the XML):
<?xml version="1.0" encoding="utf-8"?>
<TcPLMXML>
<TCifEngPart item_id="1-3000-3630-00"
seMaterialType="HALB"
uom="ST"
seWeight="2000.0" seWeightUnit="KG">
</TCifEngPart>
<TCifEngPart item_id="1-30000-41002-00"
seMaterialType="HALB"
uom="ST"
</TCifEngPart>
</TcPLMXML>
and my transformation:
<tt:loop ref="MATERIAL_LIST">
<TCifEngPart>
<tt:attribute name="item_id" value-ref="MATNR"/>
<tt:attribute name="object_name" value-ref="MATL_DESC"/>
<tt:attribute name="seMaterialType" value-ref="MATL_TYPE"/>
<tt:attribute name="uom" value-ref="BASE_UOM"/>
<tt:cond>
<tt:attribute name="seLength" value-ref="LENGTH"/>
<tt:attribute name="seWidth" value-ref="WIDTH"/>
<tt:attribute name="seHeight" value-ref="HEIGHT"/>
</tt:cond>
<tt:skip>
<tt:attribute name="seWeight" />
<tt:attribute name="seVolume" />
</tt:skip>
</TCifEngPart>
</tt:loop>
Length, width and hight are optional in the XML and will be transferred to the corresponding SAP fields if they are in the input file Weight and volume will be ignored.
This means all attributes I don't need I have to put within the tt:skip.
Without this skip the transformation throws an error.
In consequence if the partner system add new attributes I have to enhance the transformation in SAP.
Is there any other way? -
How to check the element in xml file by xpath
hi all,

for the following XML file,
* I want to check whether
the element (sage) is present or not in the following xml file XPATH expression...

Hello,
From a provider we get the following XSD from a response message:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://xxx" targetNamespace="http://yyy">
<xsd:element name="loginResponse" type="loginResponse" />
<xsd:complexType name="loginResponse">
<xsd:sequence>
<xsd:element name="result" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
His actual response looks like this:
<SOAP-ENV:loginResponse
xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/'
xmlns:SOAPENC='http://schemas.xmlsoap.org/soap/encoding/'
xmlns:xsd='http://www.w3.org/2001/XMLSchema'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-Instance'>
<Result xsi:type='xsd:string'>artv8uv38gvqu05gjohv26g8l5</Result>
</SOAP-ENV:loginResponse>
PI accepts this well, but during the conversion from XML to ABAP we get the following error:
PARSE_APPLICATION_DATA Error during XML => ABAP conversion (Response Message; error ID: CX_ST_MATCH_ELEMENT; (/1SAI/TXS3656E9BD8
Error during XML => ABAP conversion (Response Message; error ID: CX_ST_MATCH_ELEMENT; (/1SAI/TXS3656E9BD8A34AE8B7F16 XML Bytepos
Element 'loginResponse' verwacht
I have the impression that there is a problem with the namespace and wonder how I can solve this. I do not know enough about XML to judge if the returned XML is valid according to the definition. Maybe the problem lies there.
Thanks for any help.
KrisYou are right. The error is the root node:
SOAP-ENV:loginResponse
This prefix is not allowed.
It should be something like this:
<loginResponse xmlns="http://xxx"

Friends,
I am intrigued with the following date comparison logic. This is a small snippet that I cut&paste from SAP code and modified to check whether the logic is correct.
the logic below writes STATUS 68. From SAP point of view and I agree, that it should not write 68.
Can you please elaborate the problem here.
Thanks in advance.
William

Moderator message: please choose more descriptive titles for your posts, everybody here has ABAP questions...
Edited by: Thomas Zloch on Feb 20, 2012Ok, here is the function module
Please note i_aedat is the change date in the decentral and l_aedat is the changed date in the central
The function module determine whether the existing central date is before the Decentrla date.
If so it would update the central data with decentral data.
Code below produce 68 at our installation and it does not with Vijaj and Patrick. I concur with their reply.
The code that I have provided is how the function module behaves.
So is it a kernel issue?
Any help is much appreciated.
Thanks

Hi !
I wanted to ask few Abap questions :
1. How do i show a calendar on select options date field ?
2. what is the name of the function for changes currencies of field ? for example i need to change from type Usd to Euro ?
3. What is the function for abstract , adding dates fields ? ( not to take in account a Saturday and not working days ).
thanks
mosheHi Moshe,
For Calender if you any field to which the domain DATUM is assigned it shows calender.
for eg,
select-options date for P0000_AF-hiredate.
You can try the function module to add the days WDKAL_DATE_ADD_FKDAYS.
One of the function modules to convert currency is HR_ECM_CONVERT_CURRENCY
Thanks
