Parsing xml to and replacing specific tags shell script

Question

For the below xml ,I need to replace for CLASSA to failed

Answer 1

xlmlint, as the name implies, is for parsing and validating XML, not editing it. If you can install xmlstarlet on your cluster, you can do the following:

xmlstarlet ed --update "/studentFile/student[studentName='CLASSA']/studentActions/studentAction[studentType='Juniour']/studentStatus" --value "Failed" *file*
