Re: Good way to do lookups...

Bob,

You say it yourself use the string.split to create arrays of words.

Know that there are more split methods and as well much overloaded methods.

The opposite from the split is the join

I hope this helps,

Let's say that I have a table with like 525 records where each record
contains a string to look for and a string to replace with (e.g.
AVENUE, AVE). What I need to do is parse through a string (a street
address) and then for each "word/token" found, I want to look it up and
replace it if I find it in one of the 525 records. I have two
questions...

1) Is there an easy way to tokenize a string (i.e. split it out into
its separte words, where words are separated by a space)? For example,
tokenizing "Eden Hill Str" would result in three "words": "Eden",
"Hill", and "Str".

2) What would be the best way to facilitate searching for each token?
One way to do it would be to use a dataset and then there's probably
some kind of lookup function I could use (which would take advantage of
primary key field which we are actually looking up). Is that the best
way or is there a better one?
