how do i tokenize a string? 1

[cpu90]

hi guys, i have this ergent problem: i read in a line from a file, and i want only part of it, how do i split the line that i just read?
so here is the code:

buf = file.ReadLine

lets say the line is "Hello everybody here", so now buf is that line. but how do i get "Hello" or "everybody" from buf ? i can't just go for buf[1] as its index, i'm lost, sombody plz help, i need it asap

There are at least two ways to do this. I will present the brute force method:

strString = "Hello everyone out there."

strLen = Len(strString)
' iterate through string
For nCount = 1 To strLen - 1
   ' find position of character 
   nSpacePos = Instr(strString, " ")
   If nSpacePos > 0 Then
      strToken = Left(strString, nSpacePos - 1)
      nStrLen = Len(strString)
      ' truncate string to remove token
      strString = Right(strString, nStrLen - nSpacePos)
   End If
Next

However, I think a better way would be to use the RegExp object. Do a keyword search here for RegExp. There is an excellent post by clarkin under the topic "Regular Expression Help - Almost got it..." that describes how to use the RegExp object.

You can simplify the brute force solution by using the Split function, eg

buf=Split(file.readline," &quot

strongm,
Thanks, that's a good one! And I didn't even start this thread.

Split() and Replace() are the VBscript functions you probably want to check out for your string manipulation (see Zymurgyst's link).

But it's quite likely Regular Expressions can do everything you want & more - they just take a little sideways push to get your head around their slightly different approach (as compared to tokenizing and working from there).

This page is very comprehensive:

I've helped out a few peeps with Reg Exps in this forum - let us know what you are trying to achieve with your tokenized string? It may be Reg Exps are better than tokenizing. " i want only part of it " - probably means they will be ideal
