Create user-defined function with xml

[Former Member]

Hi,

I need to do a user defined function inside a mapping where i want the result to be an XML:

from fields are string 1 and string 2. that needs to create a result like this:

<Header xmlns="http://namespace1"><User>[string1]</User><Pass>[string2]</Pass></Header>

How could that be done (i need som JAVA help )

Hi,

try this one (the input parameters of the UDF are String1 and String2):

String result = new String();
result = '<Header xmlns="http://namespace1"><User>' + String1 + '</User><Pass>' + String2 + '</Pass></Header>';

return result;

Thank God that we have ABAP I have solved the problem with inspiration of the blog from Michal Krawczyk...

The User-Defined function return the xml with &lt; and so on. And then i add an ABAP mapping in the Message Mapping who replaces the signs '&lt;', '&gt;' and '&quote&.

Maybee not the nicest solution - but it works!

Thanks for all your help...

Hi,

Well i´ve got something to work, but still i have some problems: it seems that the < and > are translatet to &lt; and &gt; and the browser the consider the xml as text?

What is wrong?

Hi,

It will be translated that's the standard. In my opinion you won't achieve that in graphical mapping at least not in UDF.

Please check that website:

But I think that it won't satisfy you.

Hi,

I thin kboth are on the way - BUT the "//" in the namespace gives me some problems because it is interpreted as an Comment?

This means that after the // the code is commented out?

You're right. Then you have to concat the fields. Try This one:

String result = new String();
result = Const1 + String1 + Const2 + String2 + Const3;
return result;

Const1-3 are Constants where you put in the XML parts:

Const1: <Header xmlns="http://namespace1"><User>

Const2: </User><Pass>

Const3: </Pass></Header>

Hi Dominic,

Well - how do i declare the Constants then?

Hi,

You define a UDF with the 5 input variables Const1, String1, Const2, String2 and Const3.

Than you mapp the funtion:

- Constant with your XML value (you find Constant under the standard functions Constants)

- String1 (this is your value from the source

- Constant with your XML value (you find Constant under the standard functions Constants)

- String2 (this is your value from the source

- Constant with your XML value (you find Constant under the standard functions Constants)

Create any UDF with cache as Value.

Input the 2 Strings you want to use in XML as the Input parameters in the UDF

and Add the following line of code.

// Write code here

String xmlOutput = null ;

xmlOutput = "<Header xmlns=\"http://namespace1\"><User>"string1"</User><Pass>"string2"</Pass></Header>";

return xmlOutput;

// code ends

Hope this helps.
