String Split in DXL

Question

I have a string

Ex: "We prefer questions that can be answered; not just discussed "

now i want to split this string from ";" like We prefer questions that can be answered and not just discussed

is this possible in DXL.

i am learning DXL, so i don't have any idea whether we can split or not.

Note : This is not a home work.

Answer 1

Quick join&split I could come up with. Seams to work okay.

int array_size(Array a){
    int size = 0;
    while( !null(get(a, size, 0) ) )
        size++;
    return size;
}

void array_push_str(Array a, string str){
    int array_index = array_size(a);

    put(a, str, array_index, 0);
}

string array_get_str(Array a, int index){
    return (string get(a, index, 0));
}

string str_join(string joiner, Array str_array){
    Buffer joined = create;
    int array_index = 0;

    joined += "";

    for(array_index = 0; array_index < array_size(str_array); array_index++){
        joined += array_get_str(str_array, array_index);
        if( array_index + 1 < array_size(str_array) )
            joined += joiner;
    }

    return stringOf(joined)
}

Array str_split(string splitter, string str){
    Array tokens = create(1, 1);
    Buffer buf = create;
    int str_index;

    buf = "";

    for(str_index = 0; str_index < length(str); str_index++){
        if( str[str_index:str_index] == splitter ){
            array_push_str(tokens, stringOf(buf));
            buf = "";
        }else{
            buf += str[str_index:str_index];
        }
    }
    array_push_str(tokens, stringOf(buf));

    delete buf;
    return tokens;
}
