xml数据岛源码，啥地方不对啊

[OICQshenshi]

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"?

[hejunbin]

document.write(xmldom.selectSingleNode("xml/foo"));

2楼代码还是不行啊

[shenpengbird]

帮你顶

[cds27]

xmldom在哪?

[rczjp]

myDocument.async=false;

[highreport]

肯定是你的写法有问题,过程是没有问题

[OICQshenshi]

重新贴下代码：

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(myDocument.selectSingleNode("xml/foo"));
}
</SCRIPT >

原文红字部分为何有\"xmldataisland\"这种怪写法，与前面"xmldataisland"不对应阿，奇怪了

IE执行后为
IE XML data island: .. undefined

为何会undefined？ myDocument.loadXML(xmlString); 这句似乎失效 注释了 document.write(myDocument.selectSingleNode("xml/foo")); 后啥都取不到

没人会吗？

[什么都不能]

\转码

[什么都不能]

<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>

终于搞定了，3Q

[OICQshenshi]

最后的问题，谁能解释下，谢谢。
<xml id=\"xmldataisland\" > 为什么要加'\'

[OICQshenshi]

转码？xml学了也有段时间了，第一次看见这种用法，但还是理解不了，能给点资料吗？一定结分

[什么都不能]

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
