Unable to extract a tag from a very long XML message
Hi

I have a log file which contain XML message. I want to extract the value between the tag : <businessEventId>13201330</businessEventId> i.e., 13201330.

I tried the following commands but as the message is very long, unable to do it. Attached is the log file. Please provide inputs.

-- awk -F'[<|>]' '/<businessEventId>/{f=1}/<businessEventId>/{f=""}f{print $3}' file

-- sed -n 's/<businessEventId>\([^<]*\)<.*/\1/p' found.xml

-- awk -F '</?businessEventId>' '{print $2}' found.txt

-- awk '/<businessEventId/,/\/businessEventId/{
if(n<5)
print
if(index($0,"/businessEventId")!=0)
n++
}' found.txt
Thanks
Sapna

if you have Python, and the tags occur on its own line.
Code:
#!/usr/bin/env python
import re
for line in open("file"):
    if "<businessEventId>" in line:
        print re.sub("<.*?>","",line.strip())
        break

output:
Code:
# ./test.py
13201330

Code:
sed -n '/business/s/<businessEventId>\(.*\)<\/businessEventId>/\1/p'  yourfile

Edit: sry didn't see your attachment, this command will not work on one big line

new command:

Code:
sed -n '/business/s/.*<businessEventId>\(.*\)<\/businessEventId>.*/\1/p' yourfile

gives
Code:
