I have the data like 

```
U=ms&sv1=5xdUE3w0&sv2=3150912100&sv3=kuqd1nwca0&sv4= altima
U=ms&sv1=5xdUE3w0&sv2=3150912100&sv3=kuqd1nwca0&sv4= altima_dhfdbf&
U=ms&sv1=5xdUE3w0&sv2=3150912100&sv3=kuqd1nwca0&sv4= altima&ddhfy6574dfx

```

when i use `('date','sv4=(.*?)[_|&]',1,2)` i am able to get from last two only, 
then i need to use this `('data','sv4=(.*?)$',1,2)` for remaining data. 

Now I need to handle all these at a time. 

```
O/P : altima  from all the above data.

```

please suggest on this, how to handle.

Thanks!!!
