我想把xml某个标签过后的所有文本全部读出来怎么办？

[Tiyz01]

比如votes.xml文件是这样的

<?xml version="1.0" encoding="utf-8"?>
<votes id = "votesroot">
<option id = "70" movie = "建国大业" />
<option id = "71" movie = "当幸福来敲门" />
<option id = "72" movie = "风声" />
<option id = "73" movie = "2012" />
<option id = "74" movie = "后天" />
<option id = "75" movie = "花木兰" />
</votes>

-----

index.html

<script type="text/javascript">
//读取xml的函数
function loadXMLDoc(dname) {
try {
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
catch(e) {
try {
xmlDoc=document.implementation.createDocument("","",null);
} catch(e) {alert(e.message);}
}
try {
xmlDoc.async=false;
xmlDoc.load(dname);
return(xmlDoc);
} catch(e) {alert(e.message);}
return(null);
}

var xmlDoc=loadXMLDoc("votes.xml");
var root = xmlDoc.documentElement;
alert(root.InnerText);
</script>

结果是 不管alert(root.innerText);还是alert(root.innerHTML);其结果都为undefined

请问我该如何读取这个votes里边的东西?

<option id = "70" movie = "建国大业" />
<option id = "71" movie = "当幸福来敲门" />
<option id = "72" movie = "风声" />
<option id = "73" movie = "2012" />
<option id = "74" movie = "后天" />
<option id = "75" movie = "花木兰" />

楼上的资料没有什么用，希望能够读懂帖子再回答。

先读取，存入数组，才可以，再显示

楼主你没有认真看我给你发的资料，你的xml文档本来就没有text类型的节点怎么可能获取啊？

//Internet Explorer 使用loadXML()方法来解析XML字符串，而其他浏览器使用 DOMParser对象
function createXmlDoc(xmlText) {
    if (!xmlText) return null;
    try {
        var xmlDom = new ActiveXObject("Microsoft.XMLDOM")
        xmlDom.loadXML(xmlText)
        return xmlDom
    }
    catch (e) {
        try {
            return new DOMParser().parseFromString(xmlText, "text/xml");
        } catch (e) {
            return null;
        }
    }
}

    for (var i = 0; i < oNode.childNodes.length; i++) {
        if (oNode.childNodes[i].hasChildNodes()) {
            sText += getXmlText(oNode.childNodes[i]);
        }
        else {
            sText += oNode.childNodes[i].nodeValue;
        }
    }
    return sText; //FF
}

    return oSerializer.serializeToString(oNode); //FF
}

var xmlDoc =  createXmlDoc(xmlText);
alert(getXmlText(xmlDoc.documentElement));
alert(getXml(xmlDoc.documentElement));
