responseXML and getElementsByTagName in IE

[NokX]

ok - basically i'm pulling HTML into a page via AJAX. in these HTML pages there could be some javascript and if there is javascript i want to execute the script.

the following works perfect in firefox. in IE the page will be created perfectly, but it's not finding any <script> tags.

// these are parts pulled out of the overall script

    if (pagereq) {
        pagereq.onreadystatechange = loadpage;
        pagereq.open("GET", url, false);
        if (msie < 0) { pagereq.overrideMimeType("text/xml"); } // override the mime type so we can find any <script> tags - only firefox needs this
        pagereq.send("");
    }

function loadpage() {
    if (pagereq.readyState == 1) { //loading
        /* start any loading actions */
    } else if (pagereq.readyState == 4) {
        if (pagereq.status == 200) {
            document.getElementById(content).innerHTML = pagereq.responseText;
            
            if (pagereq.responseXML.getElementsByTagName("script").length) { // see if the page has any javascript
                eval(pagereq.responseXML.getElementsByTagName("script")[0].innerHTML); // execute the javascript
            }
        }
    }
}

pagereq.responseXML.getElementsByTagName("script").length returns 1 for firefox and 0 for IE in an HTML document containing <script>.

anyone know why IE isn't able to find the <script> tag within the responseXML?

try putting the script inside of the CDATA tag. I'm not too familiar with the XHR thing yet but i think that may be part of the problem

I found your post while searching for a solution to the same problem. I just fixed it by changed the Content-Type in the header of the XML document I was working with from application/xhtml+xml to text/xml. I'm able to use getElementsByTagName on it now, so hopefully the same solution works for you without breaking something else you're doing.

Good luck,
