In jQuery 1.2.1, line 783 does this:

div = doc.createElement("div")

The attributes that Firefox 2.0.0.7 creates for div are different

depending on whether a page is loaded as foo.html or foo.xml. In

particular, when the file is XML, there's no div.innerHTML, only

div.textContent. This causes a problem down on line 813:

div.innerHTML = wrap[1] + arg + wrap[2];

When the file is HTML, that statement assigns a value to both

div.innerHTML and div.textContent. When the file is XML, that

statement creates div.innerHTML and assigns its value, but does not

affect div.textContent.

A workaround is to do this:

div.innerHTML = wrap[1] + arg + wrap[2];

div.textContent = arg;

I'm not sure if this is a true workaround, because it fails if arg contains any HTML tags.

See http://pastie.caboo.se/101771. Save this code as foo.html and as

foo.xml.
