Can't modify XML/Iframe documents in IE

[john]

Two separate reports of this occurring:

$(document).ready(function(){
       var fred="<hi></hi>";
       console.log(fred);
       // Push through XML processor
       xml = loadXML(fred);
       var b = $("hi:first", xml);
       var node = $("<div class='group' >xxx</div>");
       node.appendTo(b);
});

---

I'm having a similar problem in IE. However, my code looks like this (using your syntax for creating the XML document):

var hiNode = $("hi", xml);
hiNode.text("foo");

When I run this in Firefox, the hi node in the XML document gets a text node with a value of "foo" appended to it. However, I get a type mismatch error in IE.

I can use the .text() function to retrieve text nodes from XML documents - can I also use it to set text nodes?

I worked around this problem by patching jquery-1.2.1.js as follows:

+			return this.empty().append( d.createTextNode( e ) );

 		var t = "";
 		jQuery.each( e || this, function(){

The existing code uses the page's DOM to create the text node and then attempts to append the text node to the XML document's DOM. IE does not allow adding a node from one DOM into another. The above patch checks if the current element has an ownerDocument and if so uses that to create the text node instead. Other places where a similar fix might be required, lines: 398 and 2261

Fixed in [4031] and [4029]. Thanks cdivilly for the patch which I only optimized slightly.
