DOMParser

BaselineWidely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

TheDOMParser interface providesthe ability to parseXML orHTML source code from astring into a DOMDocument.

You can perform the opposite operation—converting a DOM tree into XML or HTMLsource—using theXMLSerializer interface.

In the case of an HTML document, you can also replace portions of the DOM with new DOMtrees built from HTML by setting the value of theElement.innerHTML andouterHTML properties. These properties can also beread to fetch HTML fragments corresponding to the corresponding DOM subtree.

Note thatXMLHttpRequest can parse XML and HTML directlyfrom a URL-addressable resource, returning aDocument in itsresponse property.

Note:Be aware thatblock-level elementslike<p> will be automatically closed if anotherblock-level element is nested inside and therefore parsed before the closing</p> tag.
