Parse XML to ABAP

[Former Member]

HI Expert,

i have a big Problem to parse XMP to ABAP into an internal table with name and value,

and i will be very happy if i got an answer,

here a coding of xml ( example)

<?xml version='1.0' encoding='utf-8'?><!-- MyXmlFile.xml -->

<GUI-Description>

<Button size="normal" x="70" y="80">

<Title>Titel1</Title>

<Action>Action1</Action>

<Comment/>

</Button>

<Button size="small">

<Title>Second titel</Title>

<Action>Second action</Action>

</Button>

<Button size="big">

<Action>Action 3</Action>

<Title>Title 3</Title>

<Comment>here is the problm <test>HTML</test>-<abc>Text</abc>.</Comment>

</Button>

</GUI-Description>

withing parsing i i got tow times' TEST' as a name and the value is ' HTML' the first time, and the second time is '-'

and the same problem with 'abc' too. and 'coment' as a name and 'this is the problem' as a value.

<Comment>here is the problm <test>HTML</test>-<abc>Text</abc>.</Comment>

i want only th childs node and not the parents and here is my coding:

iterator = node->create_iterator( ).

• get current node

node = iterator->get_next( ).

• loop over all nodes

while not node is initial.

• Check if the node is an element or a text node.

case node->get_type( ).

when if_ixml_node=>co_node_element.

• element node

name = node->get_name( ).

ls_string-name = name.

when if_ixml_node=>co_node_text.

• text node

value = node->get_value( ).

ls_string-value = value.

• fill the internal table

append ls_string to gt_result.

endcase.

• ENDIF.

• advance to the next node

node = iterator->get_next( ).

endwhile.

thanx in advance Expert

perhaps use transformation

works like a charm to transfer xml to internal tables

CALL TRANSFORMATION ('ID')
    SOURCE XML it_xml_import
    RESULT order_header_in = st_sdhd1 order_conditions_in = ta_cond  order_partners = ta_parnr  order_text = ta_sdtext order_items_in = ta_sditm
      .

HI A. de Smidt ,

i have already trayed Call transformation, it didnt work, beacause i eant that coding not only for that example , but for all kind of xml-file with child nodes, but please explame me again the Parameters that you have just use for Result: i will try it again and see if it will works

thanx a lot

here is the xml file that I process with child nodes as well.

<?xml version="1.0" encoding="utf-8"?>

      </ORDER_ITEMS_IN>

      </ORDER_TEXT>

</asx:values>
</asx:abap>

after the gui upload that returns ta_xml_import I transform the xml stream with

DATA: it_xml_import TYPE string.

DATA: ta_xml_import TYPE STANDARD TABLE OF string.
DATA: wa_xml_import TYPE string.

    LOOP AT ta_xml_import INTO wa_xml_import.
      CONCATENATE it_xml_import wa_xml_import INTO it_xml_import.

    ENDLOOP.

the data from the xml is returned in bapi structures that I use directly for BAPI_SALESORDER_CREATEFROMDAT2

DATA:
  st_sdhd1   LIKE bapisdhd1,

  ta_sdtext TYPE TABLE OF bapisdtext,
  wa_sdtext TYPE bapisdtext,

  ta_schdl TYPE TABLE OF bapischdl,
  wa_schdl TYPE bapischdl,

HI A. de Smidt ,

Thanx a lot for your hepl, but with your xml-file , my coding is working perfect, without any problem,

but the problem is as i said, that there is ELEMENT as a value 'TEXT'

<Button size="big">

<Action>Action3</Action>

<Title>title3</Title>

-

---

> <Comment>Here is the problem <test>HTML</test>-<abc>Text</abc>.</Comment> <----

---

</Button>

i dont want <Comment> in my internal table with its value 'HERE IS THE PROBLEM'' ,

i want only the child nods ( <test>HTML</test> and <abc>Text</abc> )

the problem that i have is that, there is child nods withing the 'TEXT'

Thank you very much for your help

[karsten_korte]

Hi,

this is your result (gt_result):

Comment : here is the problm   
test : HTML                    
test : -                       
abc : Text                     
abc : .                        

in your loop you'll get the following nodes from the iterator:

01. node_element: Comment

02. node_text: here is the problm => Comment/here is the problm to result_table

03. node_element: test

04. node_text: 'HTML' => test/HTML to result_table

05. node_text: '-' => test/- to result_table

06. node_element: abc

07. node_text: 'Text' => abc/Text to result_table

08. node_text: '.' => abc/. to result_table

that's why you get the result at least.

Hi Karsten Korte ,

thanx a lot, you got really my problem, but please i still need some explanation , how can solve that problem in my coding,

thanx

[karsten_korte]

Hi jimkim,

ok, just to be sure. You want

test : 'HTML'                 
abc : 'Text'

without the 'Comment'-element

and not

Comment : 'here is the problm <test>HTML</test>-<abc>Text</abc>.'

or

Comment : 'here is the problm'
test : 'HTML'                 
abc : 'Text'

?

[Former Member]

HI Karsten Korte ,

as you said, only

test : HTML

abc: TEST

without Coment.

thank you very much for your help

[Former Member]

Hi Karsten Korte ,

as you've said

test : 'HTML'

abc : 'Text'

without Coment and its node_text

only

test : 'HTML'

abc : 'Text'

[karsten_korte]

you can skip the parent and iterate over the children:

*  iterator = node->create_iterator( ).
  node_list = node->get_children( ).
  iterator = node_list->create_iterator( ).

in this case you must not use the text-nodes:

*** Check if the node is an element or a text node.
            CASE node->get_type( ).
              WHEN if_ixml_node=>co_node_element.
* element node
                ls_string-name = node->get_name( ).
                ls_string-value = node->get_value( ).
                APPEND ls_string TO gt_result.
              WHEN if_ixml_node=>co_node_text.
** text node
*                ls_string-value = node->get_value( ).
** fill the internal table
*                APPEND ls_string TO gt_result.
            ENDCASE.

but this only works for node = 'Comment'-node. When you start at root node it would not iterate over the childs of the children.

Hi Karsten Korte ,

thanx for the Tipps, but i still have the same problem with parents node , is there any methods that i can get rid of them,

i have already tryed get_children and then get_length, but i get all nodes inside , wahtever text or a child, and get_depth not working good and get num_children too

thanx a lot

[karsten_korte]

you get text-nodes since they are childs too, so you have to use the filter for element-nodes.

Could you please tell us what the contents of gt_result should be at the end, which name-value-pairs should be included there from your example?

Hi Karsten Korte ,

this is an example of xml-file

<?xml version='1.0' encoding='utf-8'?><!-- MyXmlFile.xml -->

<GUI-Description>

<Button size="normal" x="70" y="80">

<Title>Titel1</Title>

<Action>Action1</Action>

<Comment/>

</Button>

<Button size="small">

<Title>Second titel</Title>

<Action>Second action</Action>

</Button>

<Button size="big">

<Action>Action 3</Action>

<Title>Title 3</Title>

<Comment>here is the problm <test>HTML</test>-<abc>Text</abc>.</Comment>

</Button>

</GUI-Description>

my result table should be like that:

-

---

NAME : VALUE

-

---

Title Titel1

Action Action1

Title Second tite

Action Second Action

Action Action 3

Title Title3

test HTML

abc text

-

---

kind regards

thank you very much, problem is solved 😆

Hey Jimkim

Could you please post the solution ?

Thanks

[Former Member]

Hi Samir,

you have to check number of children with the method num_children

if num_children = 1 then everything is ok.

herzliche Grüße

Jimy
