html-amend

Amends HTML by inserting attributes into elements, or elements into the DOM.

Information

No HTML parsing! This is good because it is quick and easy... but also limited. Currently, only the first occurrence of an element is supported. It should be fairly trivial to add advanced locators.

Package	html-amend
Description	Amends HTML by inserting attributes into elements, or elements into the DOM.
Node Version	>= 6

Usage
