Dim PlayerNameList As System.Xml.XmlNodeList = myPlayersDOM.GetElementsByTagName( Player)
对于 每个节点作为 Xml.XmlNode 在 PlayerNameList
xmlName = node.SelectSingleNode( 名称,nsmgr)
nodeName = xmlName.InnerText

node.RemoveAll()
myPlayersDOM.Save( D:\ Myy Documents on D \ Visual Studio Projects \Match Management Application \Players.xml)

解决方案
This a piece of my XML file
<Player>
<Name>John Rooks</Name>
<TeleNo>
</TeleNo>
</Player>
</Players>
I am trying to remove the bit in bold, using this code when curComboItem = " John Rooks"
nsmgr = New XmlNamespaceManager(myPlayersDOM.NameTable) Dim PlayerNameList As System.Xml.XmlNodeList = myPlayersDOM.GetElementsByTagName("Player") For Each node As Xml.XmlNode In PlayerNameList xmlName = node.SelectSingleNode("Name", nsmgr) nodeName = xmlName.InnerText If nodeName = curComboItem Then node.RemoveAll() myPlayersDOM.Save("D:\My Documents on D\Visual Studio Projects\Match Management Application\Players.xml") Exit For End If Next node
What I get is this
<Player>
</Player>
</Players>
Which ultimately results in a null exception.
Any ideas what I am doing wrong??
