ParseRule

Attributes for the node or mark created by this rule. When getAttrs is provided, it takes precedence.

Style rules can remove marks from the set of active marks.

When true, finding an element that matches this rule will close the current node.

By default, when a rule matches an element or style, no further rules get a chance to match it. By setting this to false, you indicate that even when this rule matches, other rules that come after it should also run.

For tag rules that produce non-leaf nodes or marks, by default the content of the DOM element is parsed as content of the mark or node. If the child nodes are in a descendent node, this may be a CSS selector string that the parser must use to find the actual content element, or a function that returns the actual content element to the parser.

When given, restricts this rule to only match when the current context—the parent nodes into which the content is being parsed—matches this expression. Should contain one or more node names or node group names followed by single or double slashes. For example "paragraph/" means the rule only matches when the parent node is a paragraph, "blockquote/paragraph/" restricts it to be in a paragraph that is inside a blockquote, and "section//" matches any position inside a section—a double slash matches any sequence of ancestor nodes. To allow multiple different contexts, they can be separated by a pipe (|) character, as in "blockquote/|list_item/".

A function used to compute the attributes for the node or mark created by this rule. Can also be used to describe further conditions the DOM element or style must match. When it returns false, the rule won't match. When it returns null or undefined, that is interpreted as an empty/default set of attributes.

Called with a DOM Element for `tag` rules, and with a string (the
style's value) for `style` rules.

Can be used to override the content of a matched node. When present, instead of parsing the node's child nodes, the result of this function is used.

When true, ignore content that matches this rule.

The name of the mark type to wrap the matched content in.

The namespace to match. This should be used with tag. Nodes are only matched when the namespace matches or this property is null.

The name of the node type to create when this rule matches. Only valid for rules with a tag property, not for style rules. Each rule should have one of a node, mark, clearMark, or ignore property (except when it appears in a node or mark spec, in which case the node or mark property will be derived from its position).

Controls whether whitespace should be preserved when parsing the content inside the matched element. false means whitespace may be collapsed, true means that whitespace should be preserved but newlines normalized to spaces, and "full" means that newlines should also be preserved.

Can be used to change the order in which the parse rules in a schema are tried. Those with higher priority come first. Rules without a priority are counted as having priority 50. This property is only meaningful in a schema—when directly constructing a parser, the order of the rule array is used.

When true, ignore the node that matches this rule, but do parse its content.

A CSS property name to match. When given, this rule matches inline styles that list that property. May also have the form "property=value", in which case the rule only matches if the property's value exactly matches the given value. (For more complicated filters, use getAttrs and return false to indicate that the match failed.) Rules matching styles may only produce marks, not nodes.

A CSS selector describing the kind of DOM elements to match. A single rule should have either a tag or a style property.
