how I can select All p tag with attribute MyTag?

Answer 1

Use the "has attribute" selector:

$('p[MyTag]')

Or to select one where that attribute has a specific value:

$('p[MyTag="Sara"]')

There are other selectors for "attribute value starts with", "attribute value contains", etc.

Answer 2

As described by the link I've given in comment, this

$('p[MyTag]').each(function(index) {
  document.write(index + ': ' + $(this).text() + "<br>");});

works (playable example).
