This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The read-only target property of the ProcessingInstruction interface represent the application to which the ProcessingInstruction is targeted.
For example:
<?xml version="1.0"?>
is a processing instruction whose target is xml.
A string containing the name of the application.
let parser = new DOMParser();
const doc = parser.parseFromString(
'<?xml version="1.0"?><test/>',
"application/xml",
);
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;
