You can probably also loop over the buffer contents, but for your
example a "simple" :g command would suffice. Let's see:
1) for each line, that starts with "private" followed by a word:
:g/^\s*private \w\+/
2) substitute the current line:
:s/\%(\w\+\s\+\)\{2}\(\w\)\(\w\+\);$/
3) by modifying the contents and putting it in front of it:
@xmlElement(name = "\u\1\2")\r&/
Together, this makes:
:g/^\s*private \w\+/s/\%(\w\+\s\+\)\{2}\(\w\)\(\w\+\);$/@xmlElement(name =
"\u\1\2")\r&/
