in reply to Fetching date

If performance is going to be an issue, I would suggest using the much more efficient substr function. Of course, depending on the situation the difference may be neglible, but I've worked on projects where performance was a big issue and this spared me a significant amount of cycles.

    Dave,
    I am not sure I agree with you. The AM wants to fetch all data in a specific format. The substr function extracts a substring. Perhaps you were thinking of index? While I agree that index can often be faster than a regex when detecting the precence of a string within a larger string, it requires an exact substring and is not maleable as say the \w character class in a regex. That type of flexibility seems to be required to solve this problem.

    Cheers - L~R
