[SOLVED] How to make a DXL attribute that is true if the word "shall" exists in another attribute, in IBM Rational DOORS?

How to make a DXL attribute that is true if the word "shall" exists in another attribute, in IBM Rational DOORS?

Trying to make a DXL boolean attribute (called "Is Requirement?") true if the word "shall" exists in another attribute (called "Text"), and otherwise false.

In edit-mode on the DOORS module, I click Edit -> Attributes -> "Is Requirement?" -> Edit... -> check DXL attribute -> Browse... -> New, write the code -> Ok, close all windows, Tools -> Refresh DXL Attributes

Object o
for o in current Module do{

 if((o."Text") contains "shall")
  {
   o."Is Requirement?" = "True"
  }
 else
  {
   o."Is Requirement?" = "False"
  }

}

Solution

Several aspects here:

The code for a DXL attribute is the code for one specific object and one specific attribute, the object is available in the variable obj, the attribute is available in attrDXLName. There is no loop over objects neither in DXL attributes nor in DXL layout columns.
contains has the signature int contains(Buffer b, string word, int offset), it operates on a Buffer, not on a string. You probably want to use bool findPlainText(string s, string sub, int &offset, int &length, bool matchCase[, bool reverse])
o."Text" will return an object reference. But you want to check the content of the attribute. To get the content of a string attribute, you have to cast the object reference to string, e.g. by concatenating the reference with a string. You can use obj."Text" "".
Is there really an attribute "Text" in your module? Usually, people use the attribute "Object Text".

This changes your code to

int offset, length
bool matchCase = true
obj.attrDXLName = findPlainText (obj."Object Text" "", "shall", offset, length, matchCase)

Remember that the type of your DXL attribute must be boolean for this to work.

And last but not least: Are you sure that your condition "Text contains shall" is sufficient? What about all the words that contain "shall" (https://www.thefreedictionary.com/words-containing-shall)? There are some threads about this topic somewhere in the internet. Search for "Requirement DXL shall shallow". And: is "shall" enough? What about "may", "should", "must"?
