使用LINQ将字符串值与对象递归列表进行比较 [英] Using LINQ to compare a string value with an object recursive list

问题描述

大家好，

我有一个名为权限"的查询，其中包含一个从XML文件中提取的对象列表.

在下面找到xml结构的示例:

Hi guys,

I have a query called permissions which contains an object list that I extracted from a XML file.

Find below an example of the xml structure:

<permission id="1">
  <permission id="1.1" />
  <permission id="1.2">
    <permission id="1.2.1" />
    <permission id="1.2.2" />
  </permission>
  <permission id="1.3" />
</permission>

如我们所见，我必须创建一个递归查询才能提取整个数据.现在，我需要使用该列表与另一个查询中的特定值进行比较.例如:

As we can see I have to create a recursive query in order to extract the entire data. Now, I need to use that list to compare with a specific value inside another query. For example:

var query = (from x in items.Elements()
            where (permissions.Any(i => i.Id == x.Attribute("id").Value))
            select ......

问题是Any<> operator只是将值与列表中的第一级节点进行比较.

有谁知道解决这个问题的另一种方法?我的意思是，如何获取/比较整棵树?

The problem is Any<> operator just compare the value with the first level nodes of my list.

Does anyone know a different approach to solve this problem? I mean, how to get/compare the entire tree?

Thanks in advance!
