Delete a specified node in XML

Today, C # is used to read the configuration file and delete the specified node. This is simple, but it will make a mistake if you don't pay attention to it. Come and share your experience.

Public void remove (videosource)
{

String innertext = videosource. typeid + videosource. Name + videosource. thumbpath + videosource. videopath;

Xmldocument xml = new xmldocument ();

XML. Load (system. Windows. Forms. application. startuppath + "/XML/videosourcexml. xml ");

// Obtain all the subnodes under the first videosources

Xmlnodelist = xml. selectsinglenode ("videosources"). childnodes;

Foreach (xmlnode item in xmlnodelist)

{

If (item. innertext = innertext)

{

// PS: If you use XML. removechild (item), The removed node is definitely not a child node of XML.

XML. selectsinglenode ("videosources"). removechild (item );

// Item. removeall (); All subnodes under item can be deleted.

Break;

}

}

XML. Save (system. Windows. Forms. application. startuppath + "/XML/videosourcexml. xml ");

}
