API
parseSelector([selector][, defaultTagName])
Create an element node from a simple CSS selector.
selector
string, optional — Can contain a tag-name (foo), classes (.bar),
and an ID (#baz).
Multiple classes are allowed.
Uses the last ID if multiple IDs are found.
defaultTagName
string, optional, defaults to div — Tag name to use if selector does not
specify one.
Returns
Security
Improper use of the selector or defaultTagName can open you up to a
cross-site scripting (XSS) attack as the value of tagName, when
resolving to script, injects a script element into the syntax tree.
Do not use user input in selector or use hast-util-santize.
