get next word in string

If I had a string:

"my birthday is tomorrow"

and a substring "my birthday is"

how could I get the next word after "my birthday is"?


you cant just subtract the strings from one another because the sentence could be longer:

e.g. "my birthday is tomorrow said bill"

and also the sentence could have different words on the front

e.g.

"and he said my birthday is tomorrow"


you can turn the string into an array of words

e.g.
the_string$="my birthday is tomorrow
local temp_array$[]=the_String.split(" ")

temp_array[0]="my"
temp_array[1]="birthday"

if that helps?

Global haystack:String = "did you know my birthday is tomorrow said bill"
Global needle:String = "my birthday is "


Local pos:Int = haystack.find(needle)
Local remainder:String = haystack[ pos + Len(needle)..]
Local birthday:String = remainder[0.. remainder.find(" ")]

Print birthday

great thanks,
i was using a long convoluted method to compare arrays

u r smart!

would you know how to get the second word after the substring?

SuperStrict

Global haystack:String = "did you know my birthday is tomorrow said bill"
Global needle:String = "my birthday is "


Local pos:Int = haystack.find(needle)
Local remainder:String = haystack[ pos + Len(needle)..]

Local words:String[] = SplitString(remainder , " ") 

'Local birthday:String = remainder[0.. remainder.find(" ")]

Print words[0]
Print words[1]



Function SplitString:String[](inString:String, Delim:String)
	Local tempList : String[]
	Local currentChar : String = ""
	Local count : Int = 0
	Local TokenStart : Int = 0
	
	If Len(Delim)<>1 Then Return Null
	
	inString = Trim(inString)
	
	For count = 0 Until Len(inString)
		If inString[count..count + 1] = delim Then
			tempList = tempList[..tempList.length+1]
			tempList[tempList.length-1] = inString[TokenStart..Count]
			
			TokenStart = count + 1
		End If
	Next
	tempList = tempList[..tempList.length+1]
	tempList[tempList.length-1] = inString[TokenStart..Count]
	Return tempList
End Function

thanks good one

Global haystack:String = "did you know my birthday is tomorrow said bill"
Global needle:String = "my birthday is "


Local pos:Int = haystack.find(needle)
Local remainder:String = haystack[ pos + Len(needle)..]

Local words:String[] = remainder.Split(" ") 

Print words[0]
Print words[1]

shortened it a bit

Ah, yeah, I'd completely forgotten about the split method

Didn't even know about it. That'll help me out loads with something I'm currently doing.

just a little shorter again :)

Local birthday:String = remainder.Split(" ")[0]
or just 
Print remainder.Split(" ")[0]

it would be nice if bmax had built in regex so you could do

Print remainder.Split("\s+")[0] 

because split fails if there is 2 spaces or a tab after "is"

Split! Sounds handy. Where's is this documented? Thanks.
