XML::XPath::NodeSet \- a list of XML document nodes

An XML::XPath::NodeSet object contains an ordered list of nodes. The nodes
each take the same format as described in XML::XPath::XMLParser.

.SS "\fBnew()\fP"
.IX Subsection "new()"
You will almost never have to create a new NodeSet object, as it is all
done for you by XPath.
.SS "\fBget_nodelist()\fP"
.IX Subsection "get_nodelist()"
Returns a list of nodes. See XML::XPath::XMLParser for the format of
the nodes.
.SS "\fBstring_value()\fP"
.IX Subsection "string_value()"
Returns the string-value of the first node in the list.
See the XPath specification for what \*(L"string-value\*(R" means.
.SS "\fBto_literal()\fP"
.IX Subsection "to_literal()"
Returns the concatenation of all the string-values of all
the nodes in the list.
.SS "get_node($pos)"
.IX Subsection "get_node($pos)"
Returns the node at \f(CW$pos\fR. The node position in XPath is based at 1, not 0.
.SS "\fBsize()\fP"
.IX Subsection "size()"
Returns the number of nodes in the NodeSet.
.SS "\fBpop()\fP"
.IX Subsection "pop()"
Equivalent to perl's pop function.
.SS "push(@nodes)"
.IX Subsection "push(@nodes)"
Equivalent to perl's push function.
.SS "append($nodeset)"
.IX Subsection "append($nodeset)"
Given a nodeset, appends the list of nodes in \f(CW$nodeset\fR to the end of the
current list.
.SS "\fBshift()\fP"
.IX Subsection "shift()"
Equivalent to perl's shift function.
.SS "unshift(@nodes)"
.IX Subsection "unshift(@nodes)"
Equivalent to perl's unshift function.
.SS "prepend($nodeset)"
.IX Subsection "prepend($nodeset)"
Given a nodeset, prepends the list of nodes in \f(CW$nodeset\fR to the front of
the current list.
