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?

C#

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

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.

C#

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

Provide your XML data on which you want to loop over. Secondly what is value you are getting in GetImagesList variable?

The 'var' obscures the really rather useful type information.

Getimageslist get the xml document from the table. so we need to loop through that xml file here.

What exactly GetImageList variable stores? Use debugger to find out! If it returns string of xml, you should use Parse method.
What you mean by saying you want to loop through the nodes?

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

C#

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

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

Seems sound to me.

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.
