Re: can't modify anonymous hash ({}) in scalar assignment

"$self=>{ettx} = {};"

Apart from I cannot see that particular line in the code you've posted; if it is there, it should probably be:

$self->{ettx} = {};
.....^

Update: Ah! You probably mean: $self=>{ettx} = $xml->XMLin(shift); which should be:

 $self->{ettx} = $xml->XMLin(shift);
......^

In the absence of evidence, opinion is indistinguishable from prejudice.

Yes, I apologize. I wrote the post and then deleted lines of code I had inserted for debugging but were not necessary for this. The line you mention was the problem one. And you were right about the syntax, too!. I thought => was for pointers and -> was for subs. I guess I should google that. Thanks!	[reply]

Comma Operator The "=>" operator is a synonym for the comma except that it causes its left operand to be interpreted as a string if it begins with a letter or underscore and is composed only of letters, digits and underscores. The Arrow Operator ""->"" is an infix dereference operator, just as it is in C and C++. If the right side is either a "[...]", "{...}", or a "(...)" subscript, then the left side must be either a hard or symbolic reference to an array, a hash, or a subroutine respectively. (Or technically speaking, a location capable of holding a hard reference, if it's an array or hash reference being used for assignment.) See perlreftut and perlref. Otherwise, the right side is a method name or a simple scalar variable containing either the method name or a subroutine reference, and the left side must be either an object (a blessed reference) or a class name (that is, a package name). See perlobj.	[reply]
