Removing preceeding space

I am trying to find if a certain string is found in a file.
I noticed that when i read from the file and split each line into tokens the token with which i wnat to test the search string is always preceeded with spaces.Hence the pattern matching alwasy fails, is there any function which would remove the whitespaces in a string(like how chomp behaves, removing the new line)
Thank you

is  it possible to create a pattern matching rule which ignores spaces .
$token1=" value1"
$search="value1"
I tried ($token =~/^$search)
i do not know exactly how many spaces will preceed token1.

may be u can say

$word =~ /^(\s|\s+|$search)

by this way u can escape if the space is present like what i mean is that the search will get okay
