Each `Treeprocessor` implements a `run` method that takes a pointer to an `Element` and modifies it as necessary. `Treeprocessors` must extend `markdown.Treeprocessor`. root etree.Elementr etree.Element | NonecCsdS)a Subclasses of `Treeprocessor` should implement a `run` method, which takes a root `Element`. This method can return another `Element` object, and the existing root `Element` will be replaced, or it can modify the current tree and return `None`.

Iterate over `Element`, find elements with inline tag, apply inline patterns and append newly created Elements to tree. To avoid further processing of string with inline patterns, instead of normal string, use subclass [`AtomicString`][markdown.util.AtomicString]: node.text = markdown.util.AtomicString("This will not be processed.") Arguments: tree: `Element` object, representing Markdown tree. ancestors: List of parent tag names that precede the tree node (if needed).
