delete and move number forward..in file
I have a file, can I just modify the <number> field and delete the 3rd number and move 4th number to 3rd.. (surely, delete the last digit)?

<john>
<Number>11 20 03 22 23 21 91 00 F0</Number>
<peter>
<Number>12 20 03 20 99 21 91 20 F0</Number>
<ken>
<id>
<Number>10 21 03 21 78 21 92 27 F0</Number>

output like
<john>
<Number>11 00 32 22 32 19 10 0F</Number>
<peter>
<Number>12 00 32 09 92 19 12 0F</Number>
<ken>
<id>
<Number>10 10 32 17 82 19 22 7F</Number>

Thank's all!!

see if this is what you want:
Code:
sed 's/\(Number> [0-9]* [0-9]*\) [0-9]*/\1/' filename
