sed in a while loop with special characters

Shell Programming and Scripting

I have the foolowing data file:
File1

     <p name="A">5004</p>
      <p name="B">5004</p>
      <p name="C">5004</p>
      <p name="A">15004</p>
      <p name="B">15004</p>
      <p name="C">15004</p>

In a while loop using sed (100 of line need to be replace), I need the output to File3:

     <p name="A">5006</p>
      <p name="B">5004</p>
      <p name="C">5004</p>
      <p name="A">25006</p>
      <p name="B">15004</p>
      <p name="C">15004</p>

File2 contain:

"A">5004<	"A">5006<
"A">15004<	"A">15006<

Test Command:

sed -r 's/\"A">5004/\"A">5006/g' File2  <<<<<work

#!/bin/ksh
cat File2 | while read a b
do
sed -r "s/$a/$b/g" File2 > File3
cp File3 File2 
done

Please help!:o

You don't need that while loop and it's not clear where you're using file1.
You should be doing something like this

sed -e 's/<stringa>/<stringb>/g' File2 > File3

The following string seems incorrect since you aren't quoting the second "...

's/\"A">5004/\"A">5006/g'

should be

's/\"A\">5004/\"A\">5006/g'

So at a guess you should be doing something like...

sed -e 's/\"A\">5004/\"A\">5006/g' File2 > File3

Hi,
I'm not sure all understand, but try this:

$ cat file1
   <p name="A">5004</p>
      <p name="B">5004</p>
      <p name="C">5004</p>
      <p name="A">15004</p>
      <p name="B">15004</p>
      <p name="C">15004</p>

$ cat file2
"A">5004<       "A">5006<
"A">15004<      "A">15006<

$ printf "s/%s/%s/g\n" $(<file2) | sed -f - file1
   <p name="A">5006</p>
      <p name="B">5004</p>
      <p name="C">5004</p>
      <p name="A">15006</p>
      <p name="B">15004</p>
      <p name="C">15004</p>

Regards.
