const pi = doc.createProcessingInstruction(
"xml-stylesheet",
'href="mycss.css" type="text/css"',
);
doc.insertBefore(pi, doc.firstChild);
const output = document.querySelector("output");
output.textContent = `This processing instruction's target is: ${doc.firstChild.target}`;The processing instruction line will be considered, and represented, as a Comment object.
<?xml version="1.0"?>
<pre></pre>const node = document.querySelector("pre").previousSibling.previousSibling;
const result = `Node with the processing instruction: ${node.nodeName}: ${node.nodeValue}\n`;
document.querySelector("pre").textContent = result;
