This trait adds additional methods to a a HTML DOM node.

Required Methods

fn validate_children_and_remove_comments_and_processing_instructions(
    &self,
    context: &Path
) -> Result<(), HtmlError>

Validated a HTML DOM node, removes any child comments and processing instructions.

fn parent(&self) -> Option<Self>

Returns the parent of this node. Returns None if there is no parent. Ordinarily, the 'root' node is of type 'Document'. The :root CSS pseudo-element matches the first html element node child of the root node of type 'Document', not 'Document' itself.

fn first_child(&self) -> Option<Self>

Returns the first child if extant, which may be an element, text node (or, if not preprocessed, a comment or processing instruction)

fn is_inter_element_whitespace_comment_or_processing_instruction(&self) -> bool

Used for determining siblings.

Provided Methods

fn previous_sibling(
    &self,
    skip_inter_element_whitespace_comment_or_processing_instructions: bool
) -> Option<Self>

Returns the previous sibling, or None if this is the first sibling

fn next_sibling(
    &self,
    skip_inter_element_whitespace_comment_or_processing_instructions: bool
) -> Option<Self>

Returns the next sibling, or None if this is the last sibling
