我有与类似如下结构的XML;

I've got an XML with a structure like the following;

 <items>
    <item>5</item>
    <item>3006</item>
    <item>25</item>
    <item>458</item>
    <item>15</item>
    <item>78</item>
 </items>

我如何删除的项目，其值为458只是为了澄清这一点，我不知道该项目的指标，所以只是要求删除项目[索引]将不会在这里做。 我得值删除。

How do I delete the item with the value 458. Just to clarify this, I don't know the index of that item, so simply calling delete items[index] won't do here. I have to delete by value.

任何提示？

推荐答案

使用E4X过滤和使用过滤器里面的功能，你可以删除你想要的节点的可能性：

Using e4x filtering and the possibilities of using function inside the filter you can delete the node you want :

所以结合这些相关信息，你可以这样做：

so combining these infos you can do :

var xml:XML=<items>
    <item>5</item>
    <item>3006</item>
    <item>25</item>
    <item>458</item>
    <item>15</item>
    <item>78</item>
 </items>;

 function deleteValue(xml:XML, value:String):void{
   xml.item.((text()==value) && (delete parent().children()[valueOf().childIndex()]));
 }

 deleteValue(xml, "458");

 trace(xml.toXMLString());
