Question

I’m running with this issue since a week now

I wonder to do something very simple :

Extract the XML content contained within an iframe and consume it within the parent document (in my case send the XML to an ActiveX for a signature)

here is a url where to find the the mini
project zip

my target browser is IE9/10.

Parent document :

            <!-- Main hero unit for a primary marketing message or call to action -->
        <div class="hero-unit">
            <h1>Parapheur 5.0</h1>
            <div class="alert-block">Please use buttons for actions</div>
            <div class="btn-group">
                <a class="btn btn-success btn-mini" onclick="javascript:expandViewport('viewport1');">Expand viewport &raquo;</a>
                <a class="btn btn-info btn-mini" onclick="javascript:collapseViewport('viewport1');">Collapse viewport &raquo;</a>
                <a class="btn btn-primary btn-mini" onclick="javascript:extractXml('#viewport1');">Extract XML &raquo;</a>
            </div>
            <div class="alert-block"></div>
            <iframe id="viewport1" src="xml/data.xml" width="1024px" height=""></iframe>
            <div class="alert-block"></div>
        </div>
        <div id="content" class="alert-info"></div>

application.js :

function extractXml(id,content) {
console.log("Starting extraction of XML from within IFrame : " + id);
/*
var lastIndexOfSlash = document.getElementById(id).src.lastIndexOf("/");
var doc = document.getElementById(id).src.substring(lastIndexOfSlash);
$.get('xml/'+doc,function(xml){
                    console.log(xml);
                });
*/
console.log($(id).contentDocument);}

Answer 1

it seems the only way to load the xml from the iframe under IE9 is by the execution of the following line of code.

document.getElementById("viewport1").contentWindow.document.firstChi‌​ld.nextSibling.textContent
