Description

Using jQuery 1.8.3, with this xslt file, bodyBug.xsl,

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    
    <xsl:output method="xml" indent="no" encoding="utf-8" />
    
    <xsl:template match ="/">
        <html xmlns="http://www.w3.org/1999/xhtml"> 
            
            <head>
                <title>jQuery body bug</title>
                
                <script type="text/javascript" src="jquery.1.8.3.js" ></script>
                <script type="text/javascript" src="bodyBug.js"></script>
                   
            </head>
            <body>
                <xsl:apply-templates />
            </body>
            
        </html>
    </xsl:template>
    
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    
</xsl:stylesheet>

and this xml file

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="bodyBug.xsl"  ?>

<t>
    <c>Hello</c>
    <c>World</c>
</t>

this js file, bodyBug.js,

jQuery(window).load(function(){
    alert($('c').offset().top);
});

should alert a number when the xml file is opened.

In Chrome it does, but in Firefox it does not. This error gets logged to the console:

TypeError: body is undefined
clientTop  = docElem.clientTop  || body.clientTop  || 0;

It will, however, work fine if

body.clientTop

is replaced with

document.getElementsByTagName("body")[0].clientTop

or if the xsl output is set to "html".

So somewhere jQuery is relying on the special meaning that "body" has in

an html file that it does not automatically have in an xml file (at least not in Firefox).

_comment0:	Update: I expected Chrome would be fine with document.getElementsByTagName('body')[0].clientTop, but it isn't. It wants body.clientTop. → 1358206221401537

The body there is a local var for the document.documentElement.body property. So yes, it looks like we'd need to use DOM methods to "find" the body for XML documents if we wanted to make that work. Is there a reason you need to set the output to XML? I'd be surprised if this is the only issue with processing a pure XML document and asking HTML-like things about it.
