jQuery selector for all nodes in a given namespace

问题

I can easily select all nodes with a given name in a namespace:

$("namespace\\:nodename")

But I need more: I want to select all nodes in a given namespace. Ideally, this:

$("namespace\\:*")

But the wildcard is not accepted.

TIA for your lights.

Since the all selector is not supported with a namespace, you can use it on its own (to match all the elements), then apply filter() to check the namespace yourself:

$("*").filter(function() {
    return this.nodeName.toLowerCase().indexOf("namespace:") == 0;
});
