Extract data from a file
Hello All,

I have a small xml file which looks like below:
Code:
<Check:defaultval Val="crash" value="crash_report_0013&#xA;generate_check_0020 generate_check_0022&#xA;&#xA;This is where the fault is."/>
<Check:defaultval Val="crash" value="crash_report_1001&#xA;generate_check_1001 generate_check_102 generate_check_0050&#xA;&#xA;This is where the fault is."/>
<Check:defaultval Val="crash" value="crash_report_4211&#xA;generate_check_1190&#xA;&#xA;This is where the fault is."/>
<Check:defaultval Val="crash" value="crash_report_0123&#xA;generate_check_0091&#xA;&#xA;This is where the fault is."/>

I want to extract the below data in the below format from the xml file.
Code:
crash_report_0013  generate_check_0020 generate_check_0022
crash_report_1001  generate_check_1001 generate_check_102 generate_check_0050
crash_report_4211  generate_check_1190
crash_report_0123  generate_check_0091

Any solution using any script is welcome.

Thanks,
Suvendu

Hello Yoda,

Your solution works.
Its great help.

But if my xml file is big,which contains different information with #xA attribute,then the output may be give lot of information apart from what i need.I think putting a filter using crash_report and generate_check will be a good idea.

Any suggestion how to do it using awk will be of good help

Hello Balajesuri,

It works as always expected.

If i have a huge file where i have to search only these attributes then it will give me a file where i will have lot of new line(\n).

What is the best way to minimize the new line in order to search the items in a big file.

Thanks,
Suvendu

Yes, you can search for records containing pattern: crash_report & generate_check and work only on them:
Code:
awk -F'=' '/crash_report/ && /generate_check/ {gsub(/"|&#xA\;&#xA\;.*|&#xA\;/,OFS,$3);sub(/^ /,X,$3);print $3}' file
