<div id="foo">yyy<span>xxx</span></div>
I have the the above structure for my html. I want to insert some content at yyy position. Can you let me know what will be the selector for it?
I would pass that selector to somefunction and that function will do $(selector).html('content')
var s = $('#foo span');
$('#foo').text("hello").append(s);

Or, if updating the HTML is an option, then simply wrapping yyy in a <span> will make your life a lot simpler:
$('#foo span:first-child').text("hello");
You can use jQuery .prepend() function (insert content, specified by the parameter, to the beginning of each element in the set of matched elements):
$('#foo').prepend('some content');
yyy should rellay be in a block element to allow you to easily discover it, otherwise I see no option other than the hacky:
$('#foo').html($('#foo').html().replace('yyy','')).find('span').before('new content');

I don't think there is a single magic selector that will select some plain text inside a container but not all of of the content.
If you want to replace 'yyy' with 'some content', you could do something like the following:
$('#foo').html('some content' + $('#foo span').html())
The "yyy" portion of the markup you posted is represented in the DOM as a text node. jQuery doesn't have any methods or selectors for isolating text nodes, but the DOM does.
See here (your question might be considered a duplicate of this one): How do I select text nodes with jQuery?
