HTML

Usage

The HTML filter is designed to capture HTML content, comments, and even attributes. It allows for filtering out specific tags, and you can even filter them out with basic selectors.

The filter accepts an HTML content buffer and will return one or more buffers containing just the text from HTML attributes and/or tags. The content will no longer be considered HTML.

When first in the chain, the HTML filter will look for the encoding of the HTML in its header and convert the buffer to Unicode. It will assume utf-8 if no encoding header is found, and the user has not overridden the fallback encoding.

The HTML filter uses BeautifulSoup4 to convert the Unicode content to HTML. Content is returned in individual chunks by block tags. While this causes more overhead, as each block is processed individually through the command line tool, it provides context for where the spelling errors are. If enabled, the HTML filter will also return chunks for comments and even attributes. Each type of text chunk is returned with their own category type.

Tags can be captured or ignored with the captures and ignores options. These options work by employing CSS selectors to target the tags. The CSS selectors are based on a limited subset of CSS4 selectors.

Options

Options	Type	Default	Description
`comments`	bool	`True`	Include comment text in the output.
`attributes`	[string]	`[]`	Attributes whose content should be included in the output.
`ignores`	[string]	`[]`	CSS style selectors that identify tags to ignore. Child tags will not be crawled.
`captures`	[string]	`['\|:not(script,style)']`	CSS style selectors used to narrow which tags that text is collected from. Unlike `ignores`, tags which text is not captured from still have their children crawled.
`mode`	string	`'html`	Mode to use when parsing HTML: `html`, `xhtml`, `html5`.
`namespaces`	dict	`{}`	Dictionary containing key value pairs of namespaces to use for CSS selectors (equivalent to `@namespace` in CSS). Use the an empty string for the key to define default the namespace. See below for example.
`break_tags`	[string]	`[]`	Additional tags (in addition to the default, defined block tags), to break on for context. Useful for new or currently unsupported block tags.
