Replace string with another string in bash script?

I have a .csv sheet with 3 columns and 'n' number of rows.

Column1: It defines the name of the Rule. Column2: This is the schema line present in all the test files. Column3: This is the line which has to replace the schema line (column 2).

**Rule         FINDSCHEMA               REPLACESCHEMA**

BV1013_1-1  <xlink:type="simple" />   <xlink:type="simple_ars" />
BV1013_1-2  <xlink:type="simple" />   <xlink:type="simple_arg" />
BV1014-1    <xlink:type="simple" />   <xlink:type="simple_qrs" />

Basic Idea:

And then I have a folder (logs/BV*.log) which contains 8k+ .log files. These log files contains the a line (as defined in the second column of .csv, actually it is same in all the files.

What is the Aim??

I would like to write a bash script:

Step1: It should read the .csv file line by line

Step2: Based on the cell name in column 1, it should find all the files with this name from the (logs/) folder.

Step3: find the string as defined in column 2 in those files.

Step4: And replace it with the string from column3.

Any help is valuable.
