如何遍历以下xml文件中的每个节点？ [英] How to loop through each node in the following xml file ?

问题描述

这是从数据库获取xml文档的linq查询，我想循环遍历文件中的每个节点。怎么做？

this is the linq query which gets the xml document from database and i would like to loop through each node in the file. how to do it?

var GetImagesList = (from x in NgDb.StagingXMLs where x.StagingLoadHistoryId == Convert.ToInt32(loadHistoryID) select x.Data).SingleOrDefault();

x.Data是我获取xml文件的列。



怎么办？我试图以这种方式做，但它没有将GetImagesList作为参数。

x.Data is the column where i get xml file.

How to do it? i tried to do in this way but it is not taking the GetImagesList as a parameter.

XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(GetImagesList);

推荐答案

尝试其他Load for XmlDocument。下面的一个字符串将其转换为XML文档。

Try the other Load for XmlDocument. The one below takes a string and converts it to an XML document.

XmlDocument xmldoc = new XmlDocument();
xmldoc.LoadXml(GetImagesList);

XmlDocument.LoadXml方法（字符串）（System.Xml） [ ^ ]

XmlDocument.LoadXml Method (String) (System.Xml)[^]

也许用于遍历所有节点的最佳解析方法是使用类 System。 Xml.XmlReader ：

XmlReader类（System.Xml） [ ^ ]。



查看此页面上的代码示例，首先，带有的那个（reader.Read（））{/ * ... * /} 。这是您遍历所有节点的方式。此外，这种方法可能是最快的。

Perhaps the best method of parsing used to traverse all the node is using the class System.Xml.XmlReader:
XmlReader Class (System.Xml)[^].

Look at the code samples on this page, first of all, the one with while (reader.Read()) { /* ... */ }. This is how you traverse all the nodes. Besides, this approach is probably the fastest.
