querySelector, wildcard element match?

Is there a way to do a wildcard element name match using querySelector or querySelectorAll?

The XML document I'm trying to parse is basically a flat list of properties

• I need to find elements that have certain strings in their names.
• I see support for wildcards in attribute queries but not for the elements themselves.

Any solution except going back to using the apparently deprecated XPath (IE9 dropped it) is acceptable.

[id^='someId'] will match all ids starting with someId.

[id$='someId'] will match all ids ending with someId.

[id*='someId'] will match all ids containing someId.

If you're looking for the name attribute just substitute id with name.

If you're talking about the tag name of the element I don't believe there is a way using querySelector

I was messing/musing on one-liners involving querySelector() & ended up here, & have a possible answer to the OP question using tag names & querySelector(), with credits to @JaredMcAteer for answering MY question, aka have RegEx-like matches with querySelector() in vanilla Javascript

Hoping the following will be useful & fit the OP's needs or everyone else's:

// basically, of before:
var youtubeDiv = document.querySelector('iframe[src="http://www.youtube.com/embed/Jk5lTqQzoKA"]')

// after     
var youtubeDiv = document.querySelector('iframe[src^="http://www.youtube.com"]');
// or even, for my needs
var youtubeDiv = document.querySelector('iframe[src*="youtube"]');

Then, we can, for example, get the src stuff, etc ...

console.log(youtubeDiv.src);
//> "http://www.youtube.com/embed/Jk5lTqQzoKA"
console.debug(youtubeDiv);
//> (...)

Set the tagName as an explicit attribute:

for(var i=0,els=document.querySelectorAll('*'); i<els.length;
          els[i].setAttribute('tagName',els[i++].tagName) );

I needed this myself, for an XML Document, with Nested Tags ending in _Sequence. See JaredMcAteer answer for more details.

document.querySelectorAll('[tagName$="_Sequence"]')

I didn't say it would be pretty :) PS: I would recommend to use tag_name over tagName, so you do not run into interferences when reading 'computer generated', implicit DOM attributes.

I just wrote this short script; seems to work.

/**
 * Find all the elements with a tagName that matches.
 * @param {RegExp} regEx  regular expression to match against tagName
 * @returns {Array}       elements in the DOM that match
 */
function getAllTagMatches(regEx) {
  return Array.prototype.slice.call(document.querySelectorAll('*')).filter(function (el) { 
    return el.tagName.match(regEx);
  });
}
getAllTagMatches(/^di/i); // Returns an array of all elements that begin with "di", eg "div"

i'm looking for regex + not + multiClass selector, and this is what I got.

Hope this help someone looking for same thing!

// contain abc class
"div[class*='abc']" 

// contain exact abc class
"div[class~='abc']" 

// contain exact abc & def(case-insensitively)
"div[class~='abc'][class*='DeF'i]" 

// contain exact abc but not def(case-insensitively)
"div[class~='abc']:not([class*='DeF'i])" 

css selector doc: https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors

There is a way by saying what is is not. Just make the not something it never will be. A good css selector reference: https://www.w3schools.com/cssref/css_selectors.asp which shows the :not selector as follows:

:not(selector)	:not(p)	Selects every element that is not a <p> element

Here is an example: a div followed by something (anything but a z tag)

div > :not(z){
 border:1px solid pink;
}
