xml数据岛源码，啥地方不对啊

IE XML data island:
..
<xml id= "xmldataisland ">
<foo> bar </foo>
</xml>

<SCRIPT language= "JavaScript ">
Cross-browser solution:
var xmlString = " <xml
id= "xmldataisland "> <foo> bar </foo> </xml> ";
var myDocument;

if (document.implementation.createDocument){
// Mozilla, create a new DOMParser
var parser = new DOMParser();
myDocument = parser.parseFromString(xmlString, "text/xml ");
} else if (window.ActiveXObject){
// Internet Explorer, create a new XML document using ActiveX
// and use loadXML as a DOM parser.
myDocument = new ActiveXObject( "Microsoft.XMLDOM ")
myDocument.async= "false ";
myDocument.loadXML(xmlString);
document.write(xmldom.transformNode(myDocument));
}
</SCRIPT>
ie怎么取不到 "bar "?

[解决办法]
document.write(xmldom.selectSingleNode("xml/foo"));
[解决办法]

JScript code

<SCRIPT language="JavaScript">   //Cross-browser solution: var xmlString = " <xml id=\"xmldataisland\" > <foo >bar </foo > </xml >";  var myDocument;    if (document.implementation.createDocument){   // Mozilla, create a new DOMParser   var parser = new DOMParser();   myDocument = parser.parseFromString(xmlString, "text/xml");  } else if (window.ActiveXObject){   // Internet Explorer, create a new XML document using ActiveX   // and use loadXML as a DOM parser.   myDocument = new ActiveXObject("Microsoft.XMLDOM")   myDocument.async="false";   myDocument.loadXML(xmlString);   document.write(myDocument.selectSingleNode("xml/foo").text);  }  </SCRIPT>

\转码
[解决办法]
var xmlString = " <xml id=\"xmldataisland\" > <foo >bar </foo > </xml >";
Javascript中引号表示字符串的头和尾如果字符串中包含有如：双引号、反斜杠、换行符、回车符等字符时就要用到转义
