How to get text around an element?

If I have

<div id='wrapper'>
  <fieldset id='fldset'>
    <legend>Title</legend>
    Body text.
  </fieldset>
</div>

How could I retrieve the "Body text" without retrieving the text inside of legend tag?

For instance, if I wanted to see if the text inside the fieldset contains the word "body" and change that word, while ignoring开发者_StackOverflow whatever might be in the legend? innerHTML retrieves all text from all children nodes.

Use of jQuery wouldn't be a problem.

$("#fldset").contents().eq(2).text();

Without a library --

var fldset = document.getElementById("fldset"),
    txt = fldset.lastChild.textContent || fldset.lastChild.innerText;

alert(txt);

---

This will get all the text nodes of fldset leaving out any other element and it's content:

var fldsetContent = $('#fldset').contents();
var text = '';
$(fldsetContent).each( function(index, item) {
    if( item.nodeType == 3 ) text += $.trim($(item).text());
});
alert( text );

Live example

$('#fldset').clone().find('legend').remove().end().text()

But you should also search around the SO

• Using .text() to retrieve only text not nested in child tags
• Clip content with jQuery

I can't think of a way other than

$("#result").html($("#wrapper").text().replace($("legend").text(),""));

but there should be a more elegant way. You can also create a new element as a copy of this one, remove all the children and get text. Hmm... That would be:

var newElement = $("#fldset").clone();
newElement.children().remove();
$("#result").html(newElement.text());

So doesn't matter how many and which type of children node has, this would work. Here: http://www.jsfiddle.net/wFV4c/

To turn all plain text nodes inside the field set red:

jQuery.each($('#fldset').contents(),function(index,value){
  if(value.textContent == value.nodeValue){
    $(this).wrap('<span style="color:red;" />')
  }
});
