Sentence in Object Text

llandale - Mon Sep 22 15:31:27 EDT 2014

You should be able to use Regular Expressions.  I'm going to scribble something up but not try it.

The problem is defining "Requirement Sentance".

If your requirement statement is always the 1st sentance and ends in an EOL

"A Requirement Sentance is string of characters that contains "shall" and ends with the period '.' character but contains no other periods." 

In RegExp terms this means

• "shall" must be its own word, we don't want to find "shallow" nor "marshall".  So now we have to define a "word"...
  I think this means some non-alpha character followed by "shall" followed by some non-alpha character.
• "shall" is case insensitive, "ShaLL" indeed counts.
  [sS][hH][aA][lL][lL]
•  We want ALL the characters between the periods.
  [^\.]*
• We want to strip leading white space.  Not sure about this.

So, here we go.  Maybe someone can improve it, especially stripping the leading spaces and making sure EOLs are handled

string sShallRequirement = "([^\\. ]*[^\\.]*[^a-zA-Z][sS][hH][aA][lL][lL][^a-zA-Z][^\\.]*\\.)"
Regexp reShallRequirement = regexp2(sShallRequirement)
print sShallRequirement "\n"

string GetShallRequiremrent(string sParagraph)
{ // Get the shall requirement sentance, if any.

 if (reShallRequirement sParagraph)  //
 then return sParagraph[match 1]
 else return("")
}
void Test(string sParagraph)
{
 string Sentance = GetShallRequiremrent(sParagraph)
 print "[" Sentance "]\t\t<" sParagraph ">\n"
}

Test(" shall8.")
Test(" .I shall not.")
Test(" .I shallow not.")
Test(" .I marshall not.")
Test("xyz.\n I shall not.\n xys.")

Hi Louie,

Many, many thanks for your detailed answer and the sample DXL code. Your sample code worked very well without needing any changes.  Your regular expression is very useful and extracted sentences that have shall word, The GetShallRequirement(string sParagraph) function worked well without any changes.

Thanks you so much for quick response.  Later, I will explore implementing the changes to the regular expression as per your suggestions.

Best regards,

Mike

It is wounderful Louie, I did not understand the question and you gave the correct answer in the first shoot.
