NAME
HTML::Object::XPath::Step - HTML Object XPath Step
SYNOPSIS
use HTML::Object::XPath::Step;
my $this = HTML::Object::XPath::Step->new || die( HTML::Object::XPath::Step->error, "\n" );VERSION
v0.2.0DESCRIPTION
This module represents a XPath step.
CONSTRUCTOR
new
It takes a HTML::Object::XPath object, an axis, a test name and a literal and returns a new HTML::Object::XPath::Step object.
METHODS
as_string
Returns a string representation of the step.
as_xml
Returns a string representation of the step as xml.
axis
Set or get the axis.
axis_ancestor
Provided with a context and a HTML::Object::XPath::NodeSet object, and this will add each parent until there are none found anymore, to the resulting node set and returns it.
axis_ancestor_or_self
This performs a similar function as "axis_ancestor", except it test each node and add it to the result, before going up to the next parent.
axis_attribute
Provided with a context and a node set and this will add each of its attribute object to the resulting node set and returns it.
axis_child
Provided with a context and a HTML::Object::XPath::NodeSet object, and this will add each of the children's node and returns the resulting set.
axis_descendant
Provided with a context and a HTML::Object::XPath::NodeSet object, and this will add each of the children's node and its children after that until there is none and returns the resulting set.
axis_descendant_or_self
This performs a similar function as "axis_ancestor", except it test each node and add it to the result, before going down to the next children's nodes.
axis_following
Provided with a context and a node set and this will get all the first child in the tree of the element's next sibling.
axis_following_sibling
Provided with a context and a node set and this will add its next sibling to the resulting node set and its sibling sibling and so forth. It returns the resulting node set.
axis_method
Set or get the axis method.
axis_namespace
Provided with a context and a node set and this will add each namespace of the context into the result.
axis_parent
Provided with a context and a node set and this will psh to the result array the context's parent, if any. It returns the resulting node set.
axis_preceding
Provided with a context and a node set and this will get all the last child of the previous sibling hierarchy. It returns the resulting node set.
axis_preceding_sibling
Provided with a context and a node set and this will all the previous siblings recursively. It returns the resulting node set.
axis_self
Provided with a context and a node set and this will return the node set with the provided context added to it.
evaluate
Provided with a node set or a node and this will evaluate each element of the nod set by calling "evaluate_node" for each of them and adding the result to a new node set and returns it.
evaluate_node
Provided with a context and this will evaluate the context, by calling the method set in "axis_method" and passing it the context and a new node set. It returns the new node set.
filter_by_predicate
Provided with a node set and a predicate and this will evaluate each element in the node set with the predicate. Based on the result, it will add the node evaluated to a new node set that is returned.
literal
Set or get the literal value.
new_nodeset
Returns a new node set object passing it whatever arguments was provided.
node_test
Provided with a node and this will test it based on the test set for this step and return a certain value; most of the time a simple true value.
test
Set or get the test name (or actually number) to be performed.
test_attribute
Provided with a node and this will test its attribute.
test_namespace
Provided with a node and this will test its name space.
