I need this to match some packets stored in XML (actually PDML) format. I use XML::Parser to parse the document, and when I detect an end tag </packet> I want to see if that packet meets some conditions or not.

I need this to determine some phases of the packet flow, so I will have about 6 packet types that have to be matched, and that has to be extensible and easily modifyable, so I don't want to hardcode it. Security is not a concern, it's for a personal project.

Thanks for the answers so far.
