Very often, you want the same transformers to run on all the

Content

anchors in a Parser. You can configure the format component of the Parser with default transformers. This saves you the trouble of adding the same transformers to every anchor in the Parser.

To do this, nest the transformers in the

default_transformers

property of the format. For more information, see Format Component Reference.

Many of the predefined format components include default transformers. For example, the

HtmlFormat

component has default transformers that remove HTML tags from the output and convert HTML entities to plain text. You can change the default transformers by editing the

default_transformers

property.

If an anchor has its own transformers, they run after the default transformers.

You can cancel the default transformers for particular anchors. To do this, set the

ignore_default_transformers

property of the anchor.
