grep portion of a string using awk 1

[viadisky]

Hi,

I would like to grep 157 from here --> <text_string>157</text_string>

I prefer using awk ... please help

Cheers!

Hi

I think you want to clear all XML-like tags, so :

awk '{gsub(/<[^<>]*>/,"");print}' /input/file

But if you want to extract the value marked by two "text_string" tags, then :

awk '{print gensub(/.*<text_string>(.*)<\/text_string>.*/,"\\1","")}' /input/file

I prefer using awk

I prefer [tt]sed[/tt].

sed 's/<[^<>]*>//g' /input/file
[gray]# or[/gray]
sed 's/.*<text_string>\(.*\)<\/text_string>.*/\1/' /input/file

The second solutions will not work well if there are input lines without that markup. Specify more about the input format if needed.

Hi Feherke,

Thanks for your suggestion

You are absolutely right, sed is better for this type of text manipultaion. It is a lot easier to intergrate it with my script.

Cheers,
