DOMParser
The DOMParser
interface provides
the ability to parse XML or HTML source code from a
string into a DOM Document
.
You can perform the opposite operation—converting a DOM tree into XML or HTML
source—using the XMLSerializer
interface.
In the case of an HTML document, you can also replace portions of the DOM with new DOM
trees built from HTML by setting the value of the Element.innerHTML
and
outerHTML
properties. These properties can also be
read to fetch HTML fragments corresponding to the corresponding DOM subtree.
Note that XMLHttpRequest
can parse XML and HTML directly
from a URL-addressable resource, returning a Document
in its
response
property.
Note: Be aware that block-level elements
like <p>
will be automatically closed if another
block-level element is nested inside and therefore parsed before the closing </p>
tag.
