I am using gem nokogiri
for Nokogiri::XML::Node
manipulations.here are the some examples of performing the basics operations on the Nokogiri::XML::Node
.you can perform these operations with Nokogiri::XML::Node
.
Say for the example you have the Nokogiri::XML::Node
named node
,now here are some basic operation with this node
.
1. Get parent: node . parent #=> will return of the xpath of the node in document.
2. Get xpath: node . path #=>will return of the xpath of the node in document
3. Get node at some path in document: _node = doc . xpath ( 'some_path' )
#=>where doc is a nokogiri document.it will return a nodeset if you want to get the exact node then do this.
_node = doc . xpath ( 'some_path' )[ 0 ] or _node = doc . xpath ( 'some_path' ). first
4. Get children: node . children
#=>will return the ```nodeset``` of childs of node your can select them according to your need.
5. Add children: node . add_child ( 'child_html' )
#=> add child in as the last child.
6. Add siblings: node . add_next_sibling ( 'some_html' ) #=> add a sibling node after the node in parent.
node . add_previous_sibling ( 'some_html' ) #=> add a sibling node before the node in parent node.
7. Replace a node: node . replace ( "replace_node's_html" ) #=> replace a node by given html.
8. Styling a node: node [ 'class' ] = 'some_css_class' #=> add a css class to node.
