Question

我不太了解xml，遗憾的是我没有多少时间可以学习。

我创建了一个连接到sql数据库并写入字段的php文件

在内部xml结构中：

 <?PHP

$link = mysql_connect("localhost","root","");
mysql_select_db("myDatabase");
$query = 'SELECT * FROM users';
$results = mysql_query($query);

echo "<?xml version=\"1.0\"?>\n";

echo "<user>\n";

while($line = mysql_fetch_assoc($results)) {

    echo "<item>" . $line["user"]."</item> \n";

}


echo "</user>\n";

mysql_close($link);

?>

这有效，但我需要从swf文件中读取它：

var myXML:XML;
var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("http://localhost/users.php"));
myLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void {
    myXML = new XML(e.target.data);
    trace(myXML);
    mytext.text=myXML;
}

如何从Flash管理用户？例如，如果我想操纵第一个用户（用户[0]）我该怎么办？

我试图补充一下：

trace(myXML.user);
        mytext.text=myXML.user;

但它不起作用，我试图在互联网上找到，但这个论点太过明确。感谢

您拥有结构XML：

<user>
    <item>Ann</item>
    <item>Alice</item>
    <item>Bob</item>
    <item>Cecile</item>
</user>

您的代码中的变量 myXML 指向根节点，即用户。现在，要解决您需要的项目：

// Get all child nodes of the root, whose node name is "item".
var aList:XMLList = myXML.child("item");
// You can also write it = myXML.item; but I don't like this way
// because of possible confusion with XML class methods.

// Now you can access list items which are XML nodes.
// Note that XMLList.length() is a method, not a getter property.
for (var i:int = 0; i < aList.length(); i++)
{
    var anItem:XML = aList[i];

    // Basically you get all anItem children as XMLList
    // which consist of a single text XML node,
    // and convert it into a string.
    var aName:String = anItem.children().toXMLString();

    trace(i, aName);
}
