heres all the code involved though you probably only need to look at the top function.  i'm trying to unlink a hyperlink.  the pesky href is still staying around though which makes it still look like a hyperlink.  i've tried setting it to "" and to null.  any ideas??

function WP_Unlink(wpName) {
      HideIfOpen(); // hides menu if open
      Backup();
      var link= WP_GetClosest(wpName,"a");      
      if(!link) {
            return;
      } // end if      
      link.href= null;      
      link.style.fontFamily= currentFont;
      link.style.fontSize= WP_TranslateFontSize(currentFontSize);
      editor.focus();    
} // end function

function WP_GetClosest(wpName,tagName) {
      var editor = WP_GetIFrame(wpName);
      var ancestors = WP_GetAllAncestors(wpName);
      var ret = null;
      tagName = ("" + tagName).toLowerCase();
      for (var i in ancestors) {
            var el = ancestors[i];
            if (el.tagName.toLowerCase() == tagName) {
                  ret = el;
                  break;
            }
      }
      return ret;
}
function WP_GetAllAncestors(wpName) {
      editor = WP_GetIFrame(wpName);
      var p = WP_GetParentElement(wpName);
      var a = [];
      while (p && (p.nodeType == 1) && (p.tagName.toLowerCase() != 'body')) {
            a.push(p);
            p = p.parentNode;
      }
      a.push(editor.document.body);
      return a;
}

Hi

You might want to try setting link.href="http://www.google.com/" or "#" just to check if it works. Do some trial and erroring. See if it's one of your other functions. We can probably look through it, but it's so much faster when you narrow it down.

You might also want to try this:

Change link.href= null; to
link.outerHTML="";

setting it to inner or outer html deletes the whole thing.  i'd like to leave the text but if nothing else i can delete the whole thing and put text back in though i'd like the shorter way if there is one

that probably didn't make much sense.  setting innerHTML or outerHTML= "" made the whole thing disappear but that gives me an idea.

To remove a link is not to remove the HREF property.
This is an example showing how to replace a link with its content:

<body>
<a id="te" href="ok">hihi </a>
<script>
function unlinkA(el)
{
      document.body.replaceChild(document.createTextNode(el.innerHTML), el);
}
unlinkA(document.getElementById('te'));
</script>
</body>

To remove all links in the document, just do a loop with document.getElementsByTagName('A')

zyloch thats basically what i ended up doing.  i did this before i even read that answer from you.  your ealier post about inner and outer html gave me an idea so i did:

function WP_Unlink(wpName) {
      HideIfOpen(); // hides menu if open
      Backup();
      var link= WP_GetClosest(wpName,"a");      
      if(!link) {
            return;
      } // end if      
      link.outerHTML= "<span style= 'font-family:" + currentFont + ";font-size:" + WP_TranslateFontSize(currentFontSize) + "';>" + link.outerText + "</span>";            
      editor.focus();    
} // end function
