Is there a methodfor searching in colums just like grep does in rows, but i don't know how many colums I will have, so: awk is not good, beacuse awk {print $1$2$3} it's not a good soultion:S i have too many colums
so I want to search like:| grep downloads.sourceforge.net | grep nvu
but the text isn't separated with enters, and I want to search in columns, not in rows :S

There is always perl!
If you send an example of what you want, I can hack you quickly a 5 line perl script to do the job...

Yes, and its call SQL. If you only want to do one or two searches, you
can use perl, or awk, coreutils, etc., but if getting accurate and
reproducible results is important to you, you will need some serious
computational machinery.
Also, in awk, use {print $1, $2, $3 ;} to keep the space delimiter
between columns. And learn about the built-in variable NF. Its value
is always set to the number of fields (columns) in the current line.

It seems to me that you only want to grab urls. This should (kind of) do the
trick:
cat f37214a30.txt | perl -ne 'print "$1
" if (/href="(.+?)"/ig)'
f37214a30.txt is a file with the snippet you uploaded.
