Hi all

can I update a xml node AND write the new value in a file witout
re-write all the file ?

sample :

my xml file :

<sample>
<exo id="1" value="Test" />
</sample>

i want to modify the file like

<sample>
<exo id="1" value="Test updated" />
</sample>

is it possible ?

No. Think about it: Where are those extra 8 bytes coming from? A
file is a contiguous piece of data, you can't insert into it randomly,
it has to be reallocated. (if you wanted to get really technically, it
could potentially be possible to create a small piece and jumping
around using i nodes, but thats way beyond the scope of our discussion)
