Sed replace string with another string wrong result

Question

I need to replace ../ with ./ from below line.

<html xmlns:og="http://test.org/schema/"  xmlns:website="../test/ns/website" >

But when use the command

sed -i 's+../+./+g' ./*

The file content changed to

<html xmlns:og="htt.//test.o./sche./" xmlns:website="./te././website" >

What could be the problem.

This should do:

echo "<html xmlns:og="http://test.org/schema/"  xmlns:website="../test/ns/website" >" | sed 's|\.\./|./|g'
<html xmlns:og=http://test.org/schema/  xmlns:website=./test/ns/website >

You need to escape the . or else it mean any character.

This should work as well: sed 's+\.\./+./+g'
