• I need to use JS to parse a big HTML content and replace innerHtml's with some other data ..but if it is in attribute it should remain untouched .Further I will not be replacing with another name , but with a <span class="spellcheck_error">word</span> . I am looking for an approach like htmlcontent = some string . Use htmlparser on this and replace only the textual contens . – Nishant Commented Feb 28, 2012 at 7:51
• Input - HTML CONTENT as a text ------> Output replace spellcheck error words within a span class -----> ( Ofcourse I already have an array of words with erros ] . If the word is in some attribute just ignore it and replace only if its a text . – Nishant Commented Feb 28, 2012 at 7:58

You can use the function parameter in replace function of string

your_string = your_string.replace(<regexp>,  
     function(matched, index){
        // check matched 
        return replacement;
     }); 
}); 

ref: https://developer.mozilla/en/JavaScript/Reference/Global_Objects/String/replace

Give the id to a block, get the innerHTML, and use the replace string function:

var get=document.getElementById('test');
var str=get.innerHTML;
document.write(str.replace("Rindan's","TestNAme"));

set this back to innerHTML

see live demo on http://jsfiddle/kunalvashist/CeeDU/

this is to replace the text and not the attributes:

var aa = document.getElementsByTagName('a');
for(i=0;i<=aa.length;i++)
{
aa[i].innerText = aa[i].innerText.replace("Rindan","anyone");
}
​

You could loop all children elements of the body tag and do a replace on the innerhtml.

var body_children = document.body.children;
for(var i = 0; i < body_children.length; i++){
   var str = body_children[i].innerHTML
   body_children[i].innerHTML = str.replace("this","with this");
}
