Answer 1

Using xml/html parsers is the right way to manipulate xml/html documents. Don't use sed/awk tools for such cases.

xmlstarlet solution:

xmlstarlet ed -u "//version[1]" -v $ver test.xml

• ed - edit mode

• -u - update action

• //version[1] - xpath expression to select the first version tag

• -v $ver - the new value for selected node
