A bit of an obscure API is the DOM Parser API in JavaScript, which provides a way to parse and manipulate XML or HTML strings. One of the key methods in this API is parseFromString(), which allows you to convert a string representation of XML or HTML into a DOM document. Let's take a brief look at this method with some examples.

First of all, the basic syntax looks like this:

const parser = new DOMParser();
const xmlDoc = parser.parseFromString(string, mimeType);

Here's a breakdown of the different parts of the code:

  • parser: A DOMParser object that provides the parseFromString() method.
  • string: The first argument passed into the method, the XML or HTML string to parse.
  • mimeType: The other argument, the type of the string being parsed, usually "text/xml" for XML or "text/html" for HTML.

So for example, if I have an XML string to parse, like this one:

const xmlString = "<bookstore><book><title>JavaScript for Dummies</title><author>Jane Doe</author></book></bookstore>";

I can then use the parseFromString() method in the following manner:

const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlString, 'text/xml');

Once I've parsed the XML string, I can access elements in the parsed DOM document just like I would with any HTML document, using methods like getElementById(), getElementsByTagName(), or querySelector().

const titleElement = xmlDoc.querySelector('title');
const authorElement = xmlDoc.querySelector('author');

console.log(titleElement.textContent);
// Output: JavaScript for Dummies

console.log(authorElement.textContent);
// Output: Jane Doe

I can basically do whatever I want with the different parts of the page, whether it's XML or HTML, using any DOM methods I would normally use on an HTML page.

Finally, I can also serialize the document back to a string using the XMLSerializer API. This might be useful if you need to send the updated XML data back to a server.

const serializer = new XMLSerializer();
const newXmlString = serializer.serializeToString(xmlDoc);

You can try out the full code example from the snippets above in this CodePen.

As you can see, the parseFromString() method can be a valuable feature for parsing XML or HTML strings and working with the resulting DOM document with JavaScript. The ability to manipulate the data, extract information, and serialize it back into a string format can be particularly useful for tasks like handling XML data from web services or manipulating HTML content dynamically.

I'm sure most of you have heard of or remember Clippy, MIcrosoft's famous early AI-based document assistant. Well, you can check out most (if not all?) of Microsoft's throwback characters via Office Assistants. Click any of the characters to see the different animations (multiple for each). I honestly had never even heard of most of these characters.
