基本Flex XML-如何检查具有特定属性的节点
[英]Basic Flex XML - how to check a node with a specific attribute exists
问题描述
Really simple problem, but I am tearing my hair out looking for a solution. 
确实很简单的问题，但是我正在寻找解决方案的问题。
I have XML that looks like this: 我有看起来像这样的XML：
<Records>
<Application id='1'>
... child elements ...
</Application>
<Application id='2'>
... child elements ...
</Application>
</Records>
I want to check if an Application node exists with a given id. 我想检查是否存在具有给定id的Application节点。 If it doesn't, create it, else just append child elements directly inside it. 如果没有，请创建它，否则只需在其内部直接添加子元素。 This should be trivial, but no combination I have tried works. 这应该是微不足道的，但是我尝试过的组合却没有。
