Re: Stringing method calls

Can't you just put an eval block around the statement? Should avoid dying and leave you with an undef'd $text if one of the subnodes doesn't exist:

my $text;
eval{$elt->first_child( 'sub_elt')->first_child( 'subsubelt')->text;}

Or did I miss something?

I certainly could. The problem is that I am not the only one (I hope!) using the module, and I want to make it as easy as possible for people who are not familiar with `eval` to use the module. Maybe after all I should just add this to the documentation, along with something restating the `eval { BLOCK }` is _not_ slow (it seems that a lot of people avoid `eval` systematically on account of it being slow, when only the `eval "string"` version can be slower if included in a loop for example).
