Replace img attribute of src elements in regex

Question

Decided him, if someone needs him, he

var feed      =   feeds.entries[i].content;
var parsedFeed    =   feed.replace(/src=/gi, "tempsrc=");
var tmpHolder =   document.createElement('div');
tmpHolder.innerHTML=parsedFeed;

I have a line containing html markup that includes <img src='path.jpg'/>

I would like to run a regex for a string to replace each src attr with tmpSrc

So

 <img src='path.jpg'/>

will turn into

 <img tmpSrc='path.jpg'/>

this is in javascript by the way

and here is the root problem, posted elsewhere but not resolved

HTML RegExps .

jQuery :

$('img').each(function() {
    var src = this.src;
    $(this).attr('tmpSrc', src).removeAttr(src);
});

Answer 3

function replace() {
    var images = document.getElementsByTagName('img'),
        srcValue,
        max
        i;

    for (i = 0, max = images.length; i < max; i++) {
       srcValue = images[i].getAttribute('src');
       images[i].setAttribute('tmpSrc', srcValue);
       images[i].removeAttribute('src');
    }
}

Answer 4

like string:

input = " <img src='path.jpg'/>"; 
output = input.replace("src","tmpSrc"); 

using the DOM:

    e = document.getElementById("theimg");  
    e.tmpSrc = e.src;
   e.removeAttribute("src");

Answer 5

A message opens explaining the problems with using regular expressions to parse HTML . This is complicated and probably not worth the effort. I don’t think there is any way that is guaranteed to work.
