比较两个xml文件 [英] comparing two xml files

问题描述

我有两个下拉列表.我有两个xml文件.一个具有标题列表，另一个具有每个标题的名称列表.

如果在下拉菜单中选择了一个标题，则另一个下拉菜单应过滤该特定标题的名称.如何使用与这两个下拉列表相关的xml数据源.

我能够在第一个下拉菜单中读取并填充标题，但在另一个下拉列表中却难以进行过滤.请给我足够的信息.

嗨
我的建议是将xml读入DataTable并执行LINQ以提取为列表....由于您没有提供xml内容，因此它看起来如何

我假设将xml读入DataTable的结果在DataTable的Title和Name列中

使用以下内容获取

Hi
What i suggest is read xml into DataTable and perform LINQ to extract as a list....As you haven''t provided xml content how it looks

I assume reading xml into DataTable results in Title and Name columns in DataTable

Use following to get

   DataTable tab = new DataTable();
            tab.ReadXml(xmlContent);
              var stateList = from row in tab1.AsEnumerable().AsQueryable()
                            group row by row["Title"] into b
                            select new { Title = b.Key, StateList = from state in b.OfType<datarow>() select state["State"] };
</datarow>

在stateList上按标题显示名称列表...

希望对您有帮助....

on stateList by title it gives list of Names ...

Hope this helps you....
