column mode editing

for copying ,column mode work find.
but for editing ,column mode of npp is not good.
for example.in the following lines
            <Action type="1" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="1" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="1" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="0" message="2327" wParam="0" lParam="0" sParam="" />
            <Action type="0" message="2327" wParam="0" lParam="0" sParam="" />
            <Action type="2" message="0" wParam="42024" lParam="0" sParam="" />
            <Action type="2" message="0" wParam="41006" lParam="0" sParam="" />
if I make the type attribute to a sequence
            <Action type="1" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="2" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="3" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="4" message="2327" wParam="0" lParam="0" sParam="" />
            <Action type="5" message="2327" wParam="0" lParam="0" sParam="" />
            <Action type="6" message="0" wParam="42024" lParam="0" sParam="" />
            <Action type="7" message="0" wParam="41006" lParam="0" sParam="" />
npp can't do this.
and ,if i want to change type attribute to all 0,i can't do it either.
i can select the column with column mode,but if i press 0,only the column(s) in first line is overwroten,and in the other lines,are just deleted.
            <Action type="0" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="" message="2170" wParam="0" lParam="0" sParam=" " />
            <Action type="" message="2327" wParam="0" lParam="0" sParam="" />
            <Action type="" message="2327" wParam="0" lParam="0" sParam="" />
            <Action type="" message="0" wParam="42024" lParam="0" sParam="" />
            <Action type="" message="0" wParam="41006" lParam="0" sParam="" />
