Shell Programming and Scripting

Hello ,

I have the folowing scenario :
I have a text file as follows : (say name.txt)
ABC
DEF
XYZ

And I have one more xml file as follows : (say somexml.xml)
<Name>ABC</Name>
<Age>12</Age>
<Class>D</Class>
<Name>XYZ</Name>
<Age>12</Age>
<Class>D</Class>
<Name>DEF</Name>
<Age>12</Age>
<Class>D</Class>

I use each name from text , grep accordingly and extract three tags name,age,class from xml ..

The extraction works fine and so does grep ...but i want to move that in a loop ... i.e. as follows :

for each name in text file
do something ....(grep in xml)

i use the following command :
cat name.txt | while read someLine
set ${someLine}
name=$someLine
grep "$name" somexml.xml

but the problem here occurs during readline coz it reads a newline alongwith the name due to which it cannot grep further in xml .....
So basically i want to remove the trailing newline character.....

(I would kindly acknowledge even better and innovative ways of reading the file)

Hope my problem is clear....

Thanks and Regards,
SD

Perhaps

Code:

while read name
do
  grep -A 2 $name somexml.xml
done < name.txt

well... it still could not grep the "name" since it got a newline appended to it while using readLine ...but can you tell me what -A 2 on a grep do?

Can you post a few lines from the output of

Code:

od -c names.txt

any explanation of hat the abov does???coz i have already written the code for grep and extraction .
All i require to so is as described earlier.....

Care to look into the man pages of grep ? Perhaps your version of grep does not have this flag ?

Code:

       -A NUM, --after-context=NUM
              Print NUM lines of trailing context after matching lines.  Places
              a line containing -- between contiguous groups of matches.

The od command display the content of the file, nongraphic characters are in form of C-language escape sequences.
That command will permit us to determine if your problem comes from your data file.

An example:

Code:

$ od -c datas.txt
0000000    E   s   c   a   p   e     033       a   n   d       C   R    
0000020   \r        i   n   s   i   d   e  \n
0000031
$
