Obtaining Section Number for an Object

The Object Number attribute in full is 3.1.7.2.4.1

I want it to return just 3

The only way I can see of doing this is to find the first non-alphanumeric character and strip away everything from there to the end.

Is that really the way to do it, or is there an attribute value for "Section Number" or similar ?

The function number returns a string and a string is an array of characters. You get the first character of the array by indexing it with zero (this returns a character, not a string so in the example I have to concatenate with an empty string to get it displayed)

So in Layout DXL

string ObjectNumber = number(obj)
string SectionNumber = ObjectNumber[0] ""
display SectionNumber

How about for sections higher than 9?

I think it would be better to use a regular expression to extract the section number.

Here is an example Layout DXL to display in a column: 

Regexp sectionNum = regexp2 "([0-9]+)\\."
string objNum = number(obj)
if (sectionNum(objNum)) display objNum[match 1]

Yes, you are correct, that is a better solution

Excellent Antonio, that's exactly what I was after.

I'd just do it with intOf: 

print intOf(number(o))

That avoids the overhead of creating and deleting a regexp
