Class: Nokogiri::XML::NodeSet

new(document, list = []) {|self if block_given?| ...}

Create a NodeSet with document defaulting to list

%(path, ns = document.root ? document.root.namespaces : {})

Alias for at

&(node_set)

Set Intersection — Returns a new NodeSet containing nodes common to the two NodeSets.

-(node_set)

Difference - returns a new NodeSet that is a copy of this NodeSet, removing each item that also appears in node_set

/(*paths)

Alias for search

==(other)

Equality — Two NodeSets are equal if the contain the same number of elements and if each element is equal to the corresponding element in the other NodeSet

>(selector)

Search this NodeSet‘s nodes’ immediate children using CSS selector selector

[index] → Node or nil
[start, length] → NodeSet or nil
[range] → NodeSet or nil
slice(index) → Node or nil
slice(start, length) → NodeSet or nil
slice(range) → NodeSet or nil

Element reference - returns the node at index, or returns a NodeSet containing nodes starting at start and continuing for length elements, or returns a NodeSet containing nodes specified by range. Negative indices count backward from the end of the node_set (-1 is the last node). Returns nil if the index (or start) are out of range.

add_class(name)

Append the class attribute name to all Node objects in the NodeSet.

after(datum)

Insert datum after the last Node in this NodeSet

at(path, ns = document.root ? document.root.namespaces : {})

If path is a string, search this document for path returning the first Node. Otherwise, index in to the array with path.

at_css(*rules)

Search this NodeSet for the first occurrence of CSS rules. Equivalent to css(rules).first See NodeSet#css for more information.

at_xpath(*paths)

Search this NodeSet for the first occurrence of XPath paths. Equivalent to xpath(paths).first See NodeSet#xpath for more information.

attr(key, value = nil, &blk)

Set the attribute key to value or the return value of blk on all Node objects in the NodeSet.

attribute(key, value = nil, &blk)

Alias for attr

before(datum)

Insert datum before the first Node in this NodeSet

children()

Returns a new NodeSet containing all the children of all the nodes in the NodeSet

css(*paths)

Search this NodeSet for css paths

For more information see Nokogiri::XML::Node#css

delete(node)

Delete node from the Nodeset, if it is a member. Returns the deleted node if found, otherwise returns nil.

dup

Duplicate this node set

each() {|self[x]| ...}

Iterate over each node, yielding to block

empty?()

Is this NodeSet empty?

filter(expr)

Filter this list for nodes that match expr

first(n = nil)

Get the first element of the NodeSet.

include?(node)

Returns true if any member of node set equals node.

index(node)

Returns the index of the first node in self that is == to node. Returns nil if no match is found.

inner_html(*args)

Get the inner html of all contained Node objects

inner_text()

Get the inner text of all contained Node objects

inspect()

Return a nicely formated string representation

last()

Get the last element of the NodeSet.

length

Get the length of the node set

pop()

Removes the last element from set and returns it, or nil if the set is empty

push(node)

Append node to the NodeSet.

remove_attr(name)

Remove the attributed named name from all Node objects in the NodeSet

remove_class(name = nil)

Remove the class attribute name from all Node objects in the NodeSet. If name is nil, remove the class attribute from all Nodes in the NodeSet.

reverse()

Returns a new NodeSet containing all the nodes in the NodeSet in reverse order

search(*paths)

Search this document for paths

For more information see Nokogiri::XML::Node#css and Nokogiri::XML::Node#xpath

set(key, value = nil, &blk)

Alias for attr

shift()

Returns the first element of the NodeSet and removes it. Returns nil if the set is empty.

[index] → Node or nil
[start, length] → NodeSet or nil
[range] → NodeSet or nil
slice(index) → Node or nil
slice(start, length) → NodeSet or nil
slice(range) → NodeSet or nil

Element reference - returns the node at index, or returns a NodeSet containing nodes starting at start and continuing for length elements, or returns a NodeSet containing nodes specified by range. Negative indices count backward from the end of the node_set (-1 is the last node). Returns nil if the index (or start) are out of range.
