I need to get the value of the content attribute of a certain meta tag.

var someContent = $("meta[name=someKindOfId]").attr("content");

is how I usually do it. For business reasons, someKindOfId may be somekindofid. It could be other combinations of cases as well. I don't know.

What is the best way to search for this meta tag? Adding an id or other identifier is out of the question.

Answer

You could use the jquery filter function like so

var meta = $('meta[name]').filter(function() {
    return this.name.toLowerCase() == 'somekindofid';
});
