Reg : Simple transformations for generating XML

[Former Member]

Hello All,

I want to generate XML file in below format

<Root>

   <Node count = '1'>

       .....

       .....

   </Node>

   <Node count = '2'>

       .....

       .....

   </Node>

   <Node count = '3'>

       .....

       .....

   </Node>

</Root>

The closing node of <Node count>  is <Node>.

and the value present in single code should increment by one for every next node.

I am able to get the closing node of <Node count> as </Node>, but unable to get the counter value.

I am trying to do it be variables etc but could not get the exact logic.

Requesting to help in this regard.

With regards,

Hi Sandeep,

You can use a simple transformation to generate the xml file.

Example:

SIMPLE TRANSFORMATION

<?sap.transform simple?>

<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">

<tt:root name="ROOT"/>

  <tt:template>

    <root>

      <tt:loop ref=".ROOT" name="line">

        <node>

          <tt:attribute name="count" value-ref="$line.node.count" />

        </node>

      </tt:loop>

    </root>

  </tt:template>

</tt:transform>

REPORT

REPORT ztest_node_count.

TYPES: BEGIN OF type_node_attr,

         count TYPE i,

       END OF type_node_attr,

       BEGIN OF type_xml,

         node TYPE type_node_attr,

       END OF type_xml.

DATA: t_xml  TYPE STANDARD TABLE OF type_xml,

      s_xml  TYPE type_xml,

      strxml TYPE string.

START-OF-SELECTION.

  s_xml-node-count = 1.

  APPEND s_xml TO t_xml.

  s_xml-node-count = 2.

  APPEND s_xml TO t_xml.

  s_xml-node-count = 3.

  APPEND s_xml TO t_xml.

   CALL TRANSFORMATION znodes

    SOURCE root = t_xml

    RESULT XML strxml.

Hello Christian,

Thank you for your reply.

   By folowing your code I will get XML file as

<Root>

    <Node> 1

    </Node>

    <Node> 2

    </Node>

    <Node> 3

    </Node>

</Root>

But my requirement is

<Root>

    <Node count = "1">

     .....

        Some inner tags

     ......

    </Node>

    <Node count = "2">

      .....

        Some inner tags

     ......

    </Node>

    <Node count  = "3">

      .....

        Some inner tags

     ......

    </Node>

</Root>

count and its value is inside the xml tag.

Hi Sandeep,

The code below generates an empty tag node with an attribute count.

        <node>
          <tt:attribute name="count" value-ref="$line.node.count" />
        </node>

So if you run the report the result xml (strxml) will be:

<Root>

    <Node count = "1" />

    <Node count = "2" />

    <Node count = "3" />

</Root>

Hello Christian,

  Thank you for your reply.

Can we get the value of the attribute dynamically like from a field of internal table.

Hi Sandeep,

That's exactly what the example report is doing

Populating the internal table t_xml

   s_xml-node-count = 1.
   APPEND s_xml TO t_xml.
  s_xml-node-count = 2.
  APPEND s_xml TO t_xml.
   s_xml-node-count = 3.
   APPEND s_xml TO t_xml.

and then passing the internal table as the source for the transformation

CALL TRANSFORMATION znodes
    SOURCE root = t_xml
    RESULT XML strxml.

Hope it helps.
