delete rows between closest pattern or range
Hi

I am having some problom deleting the lines between two specific lines in a file. need to delete lines between two closest lines. i.e need to find the closest range or pattern in a file with repeating patterns.

Sample Input:
Code:
 
WARNING
<some text in n number of lines>
ERROR:2597
WARNING
<some text in n number of lines>
ERROR:0000
WARNING
<some text in n number of lines>
ERROR:4578
WARNING
<some text in n number of lines>
ERROR:1344
WARNING
<some text in n number of lines>
ERROR:0000
WARNING
<some text in n number of lines>
ERROR:3456

Now, need to delete the lines which has error number 0000. i.e delete the range from WARNING to ERROR:0000. problom here is to find the closest range between WARNING and ERROR:0000

Sample Output:

Code:
 
WARNING
<some text in n number of lines>
ERROR:2597
WARNING
<some text in n number of lines>
ERROR:4578
WARNING
<some text in n number of lines>
ERROR:1344
WARNING
<some text in n number of lines>
ERROR:3456

I tried this, but its matching the widest pattern

Code:
 
sed '/WARNING/,/ERROR:0000/ d' filename

Please help me with this.
Thanks
Sudheer.
