svg中通过parseXML()得到的node怎么用appendChild()加不上去呢？
1-------------------外层svg文件-----------
<?xml version= "1.0 " encoding= "utf-8 "?>
<svg id= "svg " width= "800 " height= "600 " xmlns:xlink= "http://www.w3.org/1999/xlink " onload= "getContentInFile(); ">
<script>
<![CDATA[
plat=document.getElementById( "plat ");

function getContentInFile(){
xmlDoc = getURL( 'test.svg ',fn)
}

function fn(xmlDoc)
{
var x = parseXML(xmlDoc.content)
s=x.getElementsByTagName( "svg ").item(0);
nodeList=s.childNodes;

for(i=0;i <nodeList.length;i++){
var node=nodeList.item(i);

if(node.nodeType==1){
alert(node);
alert(node.nodeName);
plat.appendChild(node);//here alert "wrong document " error message
}
}
}
]]>

</script>
<g id= "plat ">
<rect x= "0 " y= "60 " width= "720 " height= "450 " fill= "white " stroke= "gray " stroke-width= "1 "/>
</g>
</svg>
2----------------------------test.svg file-------------------------------
<?xml version= "1.0 " encoding= "utf-8 "?>
<svg width= "100% " height= "100% " xmlns:xlink= "http://www.w3.org/1999/xlink ">
<rect id= "backRect " x= "0 " y= "60 " width= "720 " height= "450 " fill= "white " stroke= "gray " stroke-width= "1 " />
<circle cx= "202 " cy= "312 " r= "43 " stroke= "red " stroke-width= "1 " fill= "blue " />
</svg>

如果把plat.appendChild(node);去掉，就一切正常！
我是想把test.svg文件的各个element加到外层svg文件中！也就是提取指定svg文件中的所有node

多谢呀！！！！！！！！！

[解决办法]
昨天的例子

<?xml version= "1.0 " encoding= "utf-8 "?>
<svg id= "svg " width= "800 " height= "600 " onload= "getContentInFile(); ">
<script>
<![CDATA[
function getContentInFile(){
xmlDoc = getURL( 'test.svg ',fn)
}
function fn(xmlDoc)
{
var x = parseXML(xmlDoc.content,document)
document.getElementById( "plat ").appendChild(x.firstChild)
}
]]>

</script>
<g id= "plat ">
<rect x= "0 " y= "60 " width= "720 " height= "450 " fill= "white " stroke= "gray " stroke-width= "1 "/>
</g>
</svg>
