My program will not work if inside <blog> tag will be nested <blog>. It does not happen in tests, but I suggest to add notice to the statement that <blog> tag can be only top level and cannot be nested.

Alternatively test like this may be added:
2
a
<blog>
<blog>
</blog>
b
<blog>
<friend>b</friend>
</blog>
</blog>
b
<blog>
</blog>

This is wrong test CASE....
it may be
3
a
<blog>
</blog>
b
<blog>
</blog>
c
<blog>
</blog>
