Shell Script to insert lines in between file

Question

Suppose there is one file1.txt where content is written

Ramesh
Suresh
Raman

From the below shell script ,I am reading the content name from file1 .txt and preparing the Name=$line in echo statement.(Not able to show in shell script,in line 3 of sh it is written.

while read -r line
do
   echo "<Name="$line"/>"
done <"file.txt"

There is another xml file2.xml

<project>
<target>
start
end
</target>
</project>

I want to enhance my shell script which will insert lines to file2.xml. If in file2.xml, we find pattern end, then insert the content above end , each in new line. Can anyone please help in modifying the shell script.

Output should look like:-

<project>
<target>
start
Name=Ramesh
Name=Suresh
Name=Raman
end
</target>
</project>

I would do this:

names=$(sed s/^/Name=/ file1.txt)

ed file2.txt <<END
/^end$/i
$names
.
wq
END

now:

$ cat file2.txt
<project>
<target>
start
Name=Ramesh
Name=Suresh
Name=Raman
end
</target>
</project>

You could use awk

awk 'NR==FNR{Lines=Lines "Name=" $0 "\n";next}/end/{print Lines $0 ;next}1' file{1,2}

<project>
<target>
start
Name=Ramesh
Name=Suresh
Name=Raman
end
</target>
</project>
