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

使用e4x过滤和在过滤器中使用功能的可能性，您可以删除所需的节点：

• xml.item.(text()==value) will give you the node your are looking for
• xml.item。（text（）== value）将为您提供所需的节点
• valueOf() will give you the current node you are filtering
• valueOf（）将为您提供要过滤的当前节点
• delete will delete the node
• 删除将删除该节点

so combining these infos you can do :

所以结合这些信息，你可以做：

var xml:XML=
    5
    3006
    25
    458
    15
    78
 ;

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

 deleteValue(xml, "458");

 trace(xml.toXMLString());

this should solve it. Btw this will delete all direct chilren with name "item" that have value 458.

这应该解决它。顺便说一下，这将删除名称为“item”且值为458的所有直接孩子。

delete xml.(item == "458");

To delete recursively all children and subchildren that have name "item" and value 458 use:

要递归删除名称为“item”且值为458的所有子项和子项，请使用：

delete xml..(item == "458");
