Re: How to make this substitutions without splitting the strings? (compute not reckon)

[Anonymous Monk]

The problem is that I have a very large file of such cases and split would be rather slow I reckon. Any faster way maybe?

Don't reckon, compute :)

What size is "very large file"?

Split is bound to faster , matching (or substituting) on large strings is slow in perl, for example, matching against a 30mb string might take 10 minute, while splitting the string and then matching (30mb array) takes 3 seconds
