Jacque,
I think the "in any order" part will make a single RegEx a nightmare
(although it's probably technically possible).
How about using something simple like (or scroll down for a non-RegEx
idea)
".*(dinosaur|dog|cat).*"
Then capture the actual text matched, and remove that from the
expression. So in your example, you would first match "dinosaur".
Then you would run the RegEx again as:
".*(dog|cat).*"
Which would match "cat".
Then finally:
".*dog.*"
If you're not married to RegEx, you could just do something like
this. It should be pretty speedy, as it uses array lookups, simple
comparisons, and only one pass through your text.
## put the words into an array for quick lookup
repeat for each word w in wordList
put 0 into myWords[w]
end repeat
## loop through your text and mark all of the words you find
repeat for each word w in myText
if (myWords[w] = 0) then
put 1 into myWords[w]
end if
end repeat
## check that all of your words were "marked" with a 1
put TRUE into foundThemAll
repeat for each word w in wordList
if (myWords[w] <> 1) then
put FALSE into foundThemAll
exit repeat
end if
end repeat
Sorry if this comes through twice, I'm having trouble sending to
the list.
I need a matchtext/regex that will tell me if all supplied words
exist in a block of text, regardless of their order, and ignoring
carriage returns.
For example, see if all these words: dog dinosaur cat
exist in this text:
"The purple dinosaur inadvertently stepped on the cat.<cr>
The white dog howled."
Should return true. Is there such a thing?
