zip-text-nodes

Merge the DOM of 2 elements with the same textContent.

Given 2 elements:

Hello, <strong>world!</strong>

and:

<em>Hello</em>, world!

they are merged into:

<em>Hello</em>, <strong>world!</strong>

This can be useful when running some transformations on the content of an element and successively merging the results or restoring the original markup.

const base = <>I live in <a href="it">Italy</a></>;
const grammar = highlightVerb(base);
// <>I <em>live</em> in Italy</> // e.g. the link was lost
 
zipTextNodes(base, grammar);
// <>I <em>live</em> in <a href="it">Italy</a></>
// The new `em` is copied from `grammar` to `base`

Supports overlapping and nested elements.
