Substring in a Simple Transformation. Possible?

Astashonok — Fri, 31 Jul 2020 12:05:35 GMT

Can we split string by index or by regex in simple transformation during deserialization?

For example if we have XML tag <CAR> and want to split it's value by semicolon

<CAR>TYPE:LIMOUSINE; VENDOR:DODGE; VELOCITY:150; ENGINE:V8</CAR>

into internal table

 type		vendor      velocity	engine	
limousine 	 dodge	    	150	V8

I didn't find anything about this in tt:value help. Can we do this by means of ST, something like in XSLT?

<xsl:value-ofselect="substring(concat(., ''), 1, 1)"/>

You may call an ABAP method -> ABAP documentation ST - tt:call-method, Call Static Methods.

sandra.rossi so this is not among the built-in features?

I suppose it will be impossible to run CL_ABAP_REGEX or CL_ABAP_MATCHER via tt:call. Did you try it?

If you say that it's not a "built-in function", then there's almost no built-in function at all in Simple Transformations.

I don't understand why you say it is "impossible to run [a method] via tt:call", can you explain?

I tried tt:call-method and it worked for me.

Agreed, Sandra. The wording "built-in function" is misleading here, there is no btf in ST. Okay, thanks for suggestion, I will try to run CL_ABAP_MATCHER in ST. You can post this as answer.

I tried tt:call-method and it worked for me. Of course, you can do whatever you want in the method, including the use of regular expressions.
