Question

I would like to split all elements inside html DOM node into spans with ids, for example:

lets say I have element:

<div>
<h1>Header</h1>
<h2>header2</h2>
<p class="test">this is test p</p>
</div>

and the result should be:

<div>
<h1><span id="1">Header</span></h1>
<h2><span id="2">header2</span></h2>
<p class="test"><span id="3">this</span><span id="4">is</span><span id="5">test</span> <span id="6">p</span></p>
</div>

thanks for any help

it shoul also work if there are nested images for example:

<div>
<h1>Header</h1>
<h2>header2</h2>
<p class="test"><img alt="test alt" />this is test p</p>
</div>

and the result:

<div>
<h1><span id="1">Header</span></h1>
<h2><span id="2">header2</span></h2>
<p class="test"><img alt="test alt" /><span id="3">this</span><span id="4">is</span><span id="5">test</span> <span id="6">p</span></p>
</div>

To wrap each word something like this should help:

var c = 0;                                // create a counter
$('div > *').each(function(){
    var text = $(this).html().split(' '), // split your text strings
        len = text.length,                // get lenght of splitted parts
        result = [];                      // create array
    for( i=0; i<len; i++ ) {              // looping 'len' times....
        result[i] = '<span id="'+( ++c )+'">' + text[i] + '</span>';  // populate array
    }
    $(this).html(result.join(' '));       // apply edits
});
