Need some help I don't quite get all this dot stuff

I'm trying to extract the chapter number from the text "Chapter 3" which is a previous find from the cursor position. I'm trying to use the following
$sels = $doc.text.find '(?<=Chapter )[[:digit:]](?=\\n)', 'Er-Wr', '-am'
How do I get the number three from $sels it just gives me ranges. I'm not quite hip to this type of coding any help and education appreciated.
thanks
Lou

You can get the number by
$n = $sels.subtext or
$n = $sels.substring but
find command does not know where the cursor is positioned and, with
r option, always searches from the end of the document. Try the following instead:
Code: Select all
Find '(?<=Chapter )[[:digit:]]+(?=\n)', 'Er-W', '-am'
$n = Read Selection
Prompt $n
And if you want to verify if the number has been found successfully . . .
Code: Select all
$i = Find '(?<=Chapter )[[:digit:]]+(?=\n)', 'Er-W', '-am'
if $i
$n = Read Selection
Prompt $n
else
Prompt 'Chapter number not found'
end
• I added
+ (one or more times) after
[[:digit:]] because your document may have more than nine chapters.
• You don’t need putting two
\ before
n although
Macroize does.
