# Nokogiri::XML::DocumentFragment

### Public Class Methods

new(document, tags = nil, ctx = nil) click to toggle source

Create a new DocumentFragment from `tags`.

If `ctx` is present, it is used as a context node for the subtree created, e.g., namespaces will be resolved relative to `ctx`.

    # File lib/nokogiri/xml/document_fragment.rb, line 10
    def initialize document, tags = nil, ctx = nil
      return self unless tags

      children = if ctx
                   # Fix for issue#490
                   if Nokogiri.jruby?
                     # fix for issue #770
                     ctx.parse("<root #{namespace_declarations(ctx)}>#{tags}</root>").children
                   else
                     ctx.parse(tags)
                   end
                 else
                   XML::Document.parse("<root>#{tags}</root>")                         .xpath("/root/node()")
                 end
      children.each { |child| child.parent = self }
    end

new(document) click to toggle source

Create a new DocumentFragment element on the `document`

    static VALUE new(int argc, VALUE *argv, VALUE klass)
    {
      xmlDocPtr xml_doc;
      xmlNodePtr node;
      VALUE document;
      VALUE rest;
      VALUE rb_node;

      rb_scan_args(argc, argv, "1*", &document, &rest);

      Data_Get_Struct(document, xmlDoc, xml_doc);

      node = xmlNewDocFragment(xml_doc->doc);

      nokogiri_root_node(node);

      rb_node = Nokogiri_wrap_xml_node(klass, node);
      rb_obj_call_init(rb_node, argc, argv);

      if(rb_block_given_p()) rb_yield(rb_node);

      return rb_node;
    }

parse(tags) click to toggle source

Create a Nokogiri::XML::DocumentFragment from `tags`

    # File lib/nokogiri/xml/document_fragment.rb, line 90
    def parse tags
      self.new(XML::Document.new, tags)
