E4X: extra " / > \n in Function.toSource

function a(){
  a=<?xml version="1.0"?>
  a1=<{a} a="a"/>;
  a2=<{a} a="a"></a>;
  a3=<{a} a="a">1</a>;
  x=<a> a new line 
  then a backslash \ then a slash <b a="aa 
 \  "/></a>
}

a



give ==>


function a() {
    a = <?xml "version=\"1.0\""?>;
    a1 = <{a} a="a"/>/>;
    a2 = <{a} a="a">></a>;
    a3 = <{a} a="a">>1</a>;
    x = <a> a new line \n  then a backslash \\ then a slash <b a="aa \n \\  "/></a>;
}



3 issues:-

1. extra " in processing instruction
2. extra  /> and >
3. new line and backslash not unescaped and shown as \n  \\

I dont know if they are separate bugs or the same


step:-


1. navigate attachment "extra_stuff_in_toSource.html"

2. click Input Case "0" link

3. Click "test" button

4. repeat for links 1, 2, 3, 4 ....

x=<y><{'x'} a="n" /></y>;

x

x.toXMLString()

1. extra " in processing instruction
3. new line and backslash not unescaped and shown as \n  \\
resolved....

now only issue 2 remains. ie, 
2. extra  /> and >


Also seeing 
function (){

  x12=<?xml versio n= "1.0" ?>
  x18 = <?xml version="1.0" {'encoding'}={"iso-8859-1"}"?>;
}

as valid, ie
for x12, a space between "versio" and "n" is ok
for x18, an extra " at the end is OK

Should be fixed by saved source.
