Not in any standard way. You can get a tool that goes promiscuous on your LAN and watch it all go by, but there is no spec to save anything, just transfer. You can get some idea of who talks to who, locally, if you query arp cache, but that is different on every OS. Firewalls and proxy servers can log all activity passing through them, not entire messages but packet headers.

XPath::NodeSet(3)					User Contributed Perl Documentation					 XPath::NodeSet(3)

NAME
XML::XPath::NodeSet - a list of XML document nodes DESCRIPTION
An XML::XPath::NodeSet object contains an ordered list of nodes. The nodes each take the same format as described in XML::XPath::XMLParser. SYNOPSIS
my $results = $xp->find('//someelement'); if (!$results->isa('XML::XPath::NodeSet')) { print "Found $results "; exit; } foreach my $context ($results->get_nodelist) { my $newresults = $xp->find('./other/element', $context); ... } API
new() You will almost never have to create a new NodeSet object, as it is all done for you by XPath. get_nodelist() Returns a list of nodes. See XML::XPath::XMLParser for the format of the nodes. string_value() Returns the string-value of the first node in the list. See the XPath specification for what "string-value" means. to_literal() Returns the concatenation of all the string-values of all the nodes in the list. get_node($pos) Returns the node at $pos. The node position in XPath is based at 1, not 0. size() Returns the number of nodes in the NodeSet. pop() Equivalent to perl's pop function. push(@nodes) Equivalent to perl's push function. append($nodeset) Given a nodeset, appends the list of nodes in $nodeset to the end of the current list. shift() Equivalent to perl's shift function. unshift(@nodes) Equivalent to perl's unshift function. prepend($nodeset) Given a nodeset, prepends the list of nodes in $nodeset to the front of the current list. perl v5.18.2 2002-09-02 XPath::NodeSet(3)
