I have **unpredictably** formated sentence:

```
Parameters: 123? ,345 abc#8678Alfa 666

```

I need regex matching all numbers except thoose ending with **Alfa**. Seems simple, but...

Here's my attempt:

```
([0-9]+)(?!Alfa)

```

And this is the result of regex:

```
123 345 867 666

```

**867** is result I don't want.

Can you give me a hint?
