hi, in the faq doc , it is mentioned that in the future Tie::IxHash could be use in XML::Simple. i am using v2.18 at the moment, is there any hack to preserve the order of the data in the hashref? thanks in advance,

Retaining element order is not and never will be a feature of XML::Simple. For some XML document types you might be able to hack it in by subclassing XML::Simple and overriding the new_hashref() method to supply a hashref tied to Tie::IxHash. That could solve the ABC case but it won't solve the ABA case.

The short answer is that if you care about element order then you should not use XML::Simple. XML::LibXML is an excellent alternative which for many use cases is really no harder to use than XML::Simple - as described in this article.
