I have this text file that have lines made in a certain format just like this next line

```
bla bla name1=WORD1 bla    bla name2=WORD2 bla bla name3=WORD2

```

I want to extract WORD1 WORD2 WORD3 without all the bla bla and printing them with semicolon 

```
WORD1;WORD2;WORD3

```

can this be done using only sed ?
