将 Linq 转换为 XSLT

有没有办法将 LINQ 查询转换为 XSLT？同样的方式LINQ可以转换为SQL吗？

我的意思是，如果我有一个可靠且定义良好的 XML（符合 XSD），是否有办法将 System.Linq.Expressions 下的内容编译成与该 XML 相关的 XSLT？

谢谢。

对于 Dimitries 的请求，我会尝试详细说明一下...基本上，我在一个地方有一些数据（基本上是 xml 可序列化数据块），我需要处理它们，我需要组合和处理它们。

传入的原始数据和输出结果数据都是 XML 可序列化的，并且符合定义良好的 XSD。

我想在其他地方动态生成处理逻辑。并允许我的用户更改和尝试处理。我可以用表达式树轻松地表示处理本身。表达式树与解析树类似，可以捕获程序代码。这就是 linq to SQL 的工作方式，它将表达式树转换为 SQL 查询。

由于所有收入数据和输出都是定义良好的 XML，因此我可以使用 XSLT 轻松进行转换，但我对 XSLT 还不够熟悉，无法编写动态 XSLT 生成器。因此，我认为我可以在 C# 中构建转换并将它们转换为 XSLT...同样，它不是通用 C#，但可能是对定义良好的数据提供程序的特定查询。

举例来说：（

不是真正的代码）

var schemas = XSchemaSet.Load("a","b");
var doc = XDocument.Load("File",schemas);

var result = from node in doc.Nodes
             where node.Name == "Cats" || node.Name == "Dogs"
             select (new Node(){Name = "Animal Owner", Value = node.Owner)
var newDoc = new XDocument().AddNodes(result);
newDoc.Validate(schemas);

基本上我想要一些功能类似的东西...如果我使用 IQueryable.Aggregate 我可以在单个 linq 查询中编写它

Is there a way to convert LINQ queries into XSLT? the same way LINQ can be converted to SQL?

I mean if i have a solid well defined XML(Conforms to an XSD) is there a way to compile the stuff under System.Linq.Expressions into XSLT in regard to that XML?

Thank you.

To Dimitries request I'll try to elaborate a little... Basically I have some data in one place (it's basically to chunks of xml serializable data), and I need to process them, I need to combine and process them.

Both the incoming original data , and the output result data, are XML serializable, and conform to a well defined XSD.

I want to generate the processing logic dynamically - someplace else. And allow my user to change and play around with the processing. I can represent the processing it self easily with Expression trees. Expression trees are similar to parse trees and can capture program code. This is the way linq to SQL works it converts expression trees to SQL queries.

Since all the income data and the output are both a well defined XML I can do the transformation easily with XSLT, but I'm not familiar with XSLT enough to write a dynamic XSLT generator. So I thought I could build the transformations in C# and convert them into XSLT.... again its not general purpose C#, but probably specific queries over a well defined data provider.

For the example sake:

(Not real code)

var schemas = XSchemaSet.Load("a","b");
var doc = XDocument.Load("File",schemas);

var result = from node in doc.Nodes
             where node.Name == "Cats" || node.Name == "Dogs"
             select (new Node(){Name = "Animal Owner", Value = node.Owner)
var newDoc = new XDocument().AddNodes(result);
newDoc.Validate(schemas);

Basically I want something that will function like that... I can write that in a single linq query if I use IQueryable.Aggregate
