How to choose some elements containing some Specific alphabets from an array?

[guoyu]

for example, an array contains the following elements: AA1 AA2 AAB CAA ABC   BBE  BAA  . I want to choose out the elements containing AA,that is

AA1 AA2 AAB CAA BAA. Can you give me the relevant procedures？ thank you!

Look at Match Regular Expression.  I don't know enough about the coding format to tell you what the search code would be.

Of course just doing a search string for "AA" will give you whether it exists in a particular array element or not.

The actual element type as in the example.Thank you！

I don't see how you can do that without examinig each element of the array.

The examination could be done with regular epression.

If you are not anxious about the sequence of the result you can use parallizing of loops to take advantage of your multicore.

I'm assuming his question is now solved because he did say "thank you."  He never asked any additional questions, so it must mean he understands what to do now.

".AA" matches any character string ending with AA, "|" or "AA." matches any character string starting with AA
