get text between two tags in bash (awk)
Hi,

I have a sample text file:

Code:
<category name="Temp1">something1</category><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
</TD></TR></TABLE></BODY></HTML>
<category name="Temp2">something2
</category>

New lines in the file may or may not occur.

I would like to get only those parts of the file which are between the closest 'category' tags, so in this example:

Code:
<category name="Temp1">something1</category><category name="Temp2">something2</category>

I am trying to force awk to do that like that:

Code:
awk -F "</?category.*>" '{ print $1 }' file.txt

But this command gives me only:

Code:
</TD></TR></TABLE></BODY></HTML>

Could anyone point me how to write the command properly?

Regards,
Robert
