You could set your needle to be a valid LCS expression. I just ran a test using the following: *do* "if (" & pNeedle & ") then put tPath into xFoundPaths[the number of elements in xFoundPaths + 1]" It took around 4x of the time to run though. I set my needle to "tElement > 5000" for one test

As a slightly related aside in this conversation I’d still one day like to add `each` to filter: — filter array and retain elements where element[“foo”][“bar”] = “baz" put “foo” into tPath[1] put “bar” into tPath[2] filter elements of tArray by evaluating each[tPath] is “baz” Cheers Monte

Re: Search Values of Array in "One Go"

tElement isn't the part that would change (you are still searching against a single value in the array), you would need to modify the comparison to allow for pNeedle to contain multiple values and the operators. It would probably be easier to modify to use a RegEx. If you have 2 comma separated

I created a stack to do some testing to see about making a function that could do multiple types of tests. What I found was that adding another if at that point added about 6% to the search time and a second level (else if) added another 10% (16% total). (I added a parameter for search type -

This will work with any array. It recursively calls itself as it encounters arrays within arrays. I agree with Richard that if all you want is one shot at an array to find the element(s) you are looking for, then this may (or may not) be a cleaner approach, but I think if you are taking

I'm with bob on this.. If for some reason you can't use the database that produced the array, shove the data into an sqlite db instead. In memory, or if you need persistence a db file. Alternatively, if you store your data flat rather than in an array. Then you can repeat for each line tline
