Are you looking to extract the first word from that column in each row of the table, i.e. excluding the part in italics and the part in bold?

Yes

I don't think  you can do that through css selector alone. You should be able to select the entire text with .DataText2 and then use some regex in a stringsearcher to grab just the first portion of text

f\w\s\d]+

i\w\s\d]+

Ok 

also in this case isn't possible to extract the part after span ?

article:nth-child(-n+30) > div > div:nth-child(3)> div > p:nth-child(3) > span

thx
