shell script for the changing the element of xml [duplicate]
Perhaps you mean to use sed.
value='abc'sed -i "s|abc.txt|$value|g" abc.xmlYou would have to run that in a shell, or as a shell script with the header #!/bin/sh.
---- Update ----
#!/bin/shvalue="something"sed -i "s|\(<filename>\)[^<>]*\(</filename>\)|\1${value}\2|" abc.xmlAdd g to the sed command if you need to replace multiple instances in one line.
sed -i "s|\(<filename>\)[^<>]*\(</filename>\)|\1${value}\2|g" abc.xml
