Query about node activity
Hi,
im just trying to find my way out. can anyone tell me where do nodes keep their info about which other nodes they've interacted with and when? or just where do they store details about which nodes have exchanged info with them, which nodes do they interact with? are the contents of such file encrypted?
Thanks!!

xml::xpathengine::nodeset
XML::XPathEngine::NodeSet(3pm) User Contributed Perl Documentation XML::XPathEngine::NodeSet(3pm)
NAME
XML::XPathEngine::NodeSet - a list of XML document nodes
DESCRIPTION
An XML::XPathEngine::NodeSet object contains an ordered list of nodes. The nodes each take the same format as described in
XML::XPathEngine::XMLParser.
SYNOPSIS
my $results = $xp->find('//someelement');
if (!$results->isa('XML::XPathEngine::NodeSet')) {
print "Found $results
";
exit;
}
foreach my $context ($results->get_nodelist) {
my $newresults = $xp->find('./other/element', $context);
...
}
API
new()
You will almost never have to create a new NodeSet object, as it is all done for you by XPath.
get_nodelist()
Returns a list of nodes. See XML::XPathEngine::XMLParser for the format of the nodes.
string_value()
Returns the string-value of the first node in the list. See the XPath specification for what "string-value" means.
string_values()
Returns a list of the string-values of all the nodes in the list.
to_literal()
Returns the concatenation of all the string-values of all the nodes in the list.
get_node($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.
