do you want to read the XML file stored in the frontend to ABAP program,

use GUI_UPLOAD

what do you want to do with the loaded XML? if you could explain this then we can come up with suggestions.

Hello Durai,

I would like to know how to store the xml into an internal table.

I have created a dot net application where we download data from SAP and then send mails. We display the data within a HTML table. We found type out all the code(to create the table and display data) in ABAP store it in a string and then use SO_OBJECT_SEND to send email. Instead if we can store the file and read it into an internal table, then populate the SAP data and send the email, we thought it could be useful.

Kindly advise.

Thanks and Regards,

Thiru

I would like to know how to store the xml into an internal table.

you want to store the XML as just a string then just use GUI_UPLOAD

if you want to transform the loaded XML into a internal table of rows and columns the you need to use

CALL TRANSFORMATION key word. (search the forum there were solutions).

the second part of your explantaion is not clear to me.

hi , you can parse the XML using DOM, DOM is also supported in ABAP, there is a class CL_IXML, and other associated class. you can achieve your target by using them.

reference link:

http://help.sap.com/saphelp_nw04/helpdata/en/86/8280d212d511d5991b00508b6b8b11/frameset.htm

The other way is through XLST. it is supported in ABAP from 4.7. you can create a XSLT, and read you XML, then CALL TRANSFORMATION to convert a XML into ABAP data structure.

reference link:

Hope it will be helpful

thanks

Whil I use GUI_UPLOAD, I get the following error 'Type conflict when calling a function module.

I have tried the following-

1. FILETYPE = 'ASC'

2. FILETYPE = 'BIN'

3. FILETYPE = 'XML'

None seem to work. I used WS_FILENAME_GET to select the file, at selection-screen(using f4 help, I select the file and the path is stored in p_file).

CALL FUNCTION 'GUI_UPLOAD'

for xml files better use BIN

and your variable p_file has to be of type string,

couldnt figureout the issue. but i guess you dont have any problem if the uploaded content is in binary format or ASC format.

make the following changes. (sorry for the inconvenience)

change the itab to string

and file type to 'ASC'

if you still want to have it in BIN format,

check out the program SXSLTDEMO_FLIGHTS

search for the code "perform load_file using i_path changing srctab"

you can see how the itab is built.
