I know this is 7 years old, but this is how you do it (for attribute values):

function DOMRegex(regex) {
    let output = [];
    for (let i of document.querySelectorAll('*')) {
        if (regex.test(i.type)) { // or whatever attribute you want to search
            output.push(i);
        }
    }
    return output;
}
console.log(DOMRegex(/^service\//)); // your regex here

To search all element attributes, you can use this:

function DOMRegex(regex) {
    let output = [];
    for (let i of document.querySelectorAll('*')) {
        for (let j of i.attributes) {
            if (regex.test(j.value)) {
                output.push({
                    'element': i,
                    'attribute name': j.name,
                    'attribute value': j.value
                });
            }
        }
    }
    return output;
}
console.log(DOMRegex(/(?

I put it in a nice object layout for you.
