如何將新節點添加到xml文件

Question

我在將節點添加到現有xml時遇到問題。我不確定節點是否是正確的名稱。如果不是有人請糾正我。這是一個更大，但這個例子應該做的伎倆。

這是xml文件的樣子。

<?xml version="1.0" encoding="utf-8"?> 
<MovieData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <Movie> 
     <Name>Death Race</Name> 
     <Type>Action</Type> 
     <Type>Adventure</Type> 
     <Rating>R</Rating> 
     <Disk>Blu-Ray</Disk> 
    </Movie> 
    <Movie> 
     <Name>Death Race 2</Name> 
     <Type>Action</Type> 
     <Type>Adventure</Type> 
     <Rating>R</Rating> 
     <Disk>Blu-Ray</Disk> 
    </Movie> 
</MovieData> 

現在我想它最終這樣。

<?xml version="1.0" encoding="utf-8"?> 
<MovieData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <Movie> 
     <Name>Death Race</Name> 
     <Type>Action</Type> 
     <Type>Adventure</Type> 
     <Rating>R</Rating> 
     <Disk>Blu-Ray</Disk> 
     <Time>time</Time> 
    </Movie> 
    <Movie> 
     <Name>Death Race 2</Name> 
     <Type>Action</Type> 
     <Type>Adventure</Type> 
     <Rating>R</Rating> 
     <Disk>Blu-Ray</Disk> 
     <Time>time</Time> 
    </Movie> 
</MovieData> 

這是我到目前爲止。我希望能夠添加時間節點和下面的代碼中的值。

XmlDocument doc = new XmlDocument(); 
doc.Load(movieListXML); 
XmlNode node = doc.SelectSingleNode("/MovieData"); 
foreach (XmlNode movie in node.SelectNodes("Movie")) 
{ 
    if (movie != null) 
    { 
     // Do stuff here. 
     // I'm not sure what to do here. 
    } 
} 

這也行不通。

XmlDocument doc = new XmlDocument(); 
doc.Load(movieListXML); 
XmlNode node = doc.SelectSingleNode("/MovieData"); 
foreach (XmlNode movie in node.SelectNodes("Movie")) 
{ 
    if (movie != null) 
    { 
     // Do stuff here. 
     // I'm not sure what to do here. 
     using(XmlWriter writer = node.CreateNavigator().AppendChild()) 
     { 
      writer.WriteStartElement("SeriesType", movieListXML); 
      writer.WriteElementString("Time", movieListXML, "time"); 
      writer.WriteEndElement(); 
     } 
    } 
} 

Answer 1

我通常使用Linq的的XDocument來處理XML。您需要將System.Xml.Linq添加到您的使用語句中。這將是這樣的：

 string movieListXML = @"c:\test\movies.xml"; 
     XDocument doc = XDocument.Load(movieListXML); 
     foreach (XElement movie in doc.Root.Descendants("Movie")) 
     { 
      movie.Add(new XElement("Time", "theTime")); 
     } 
     doc.Save(movieListXML); 

Answer 2

XmlDocument doc = new XmlDocument(); 
doc.Load(movieListXML); 
XmlNode node = doc.SelectSingleNode("/MovieData"); 
foreach (XmlNode movie in node.SelectNodes("Movie")) 
{ 
    if (movie != null) 
    { 
     XmlElement elem = doc.CreateElement("Time"); 
     elem.InnerText = "time"; 
     movie.AppendChild(elem); 
    } 
} 
doc.Save(movieListXML);
