带名称空间的 XML 的操作使用XmlNamespaceManager
System.Xml.XmlNamespaceManager nsmanager = new System.Xml.XmlNamespaceManager(doc.NameTable);
nsmanager.AddNamespace("","");
System.Xml.XmlNode node = doc.SelectSingleNode( "bg:equinfo[bg:Sid=37]", nsmanager);

 public XmlDocument DeleteXmlNodeByInnerText(XmlDocument xmlDoc, string NodeName, string NodeValue)
        {
            XmlNodeList xn = objXmlDoc.GetElementsByTagName(NodeName);
            foreach (XmlNode cNode in xn)
            {
                XmlElement xe = (XmlElement)cNode;
                if (xe.InnerText == NodeValue)
                {
                    xe.ParentNode.RemoveChild(cNode);
                    break;
                }
            }
            return xmlDoc;
        }

[maomaomaoaaa]

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Server.MapPath("xmlSave\\mok-25.xml"));

XmlNodeList xn = xmlDoc.GetElementsByTagName("Sid");
foreach (XmlNode cNode in xn)
{
XmlElement xe = (XmlElement)cNode;
if (xe.InnerText == "37")
{
xe.ParentNode.RemoveAll();
break;
}
}
xmlDoc.Save(Server.MapPath("xmlSave\\mok-26.xml"));

可以删除内容但是<equinfo></equinfo>删除不了

[saybookcat]

xe.ParentNode.RemoveAll();
改成 (xe.ParentNode).ParentNode.RemoveAll();

用.net3.5的 方便点

 XNamespace xn = "bagsinfo";
 XElement xmlPage = XElement.Load("../../xm1.xml");

 xmlPage.Descendants(xn + "Sid").Where(s => s.Value == "37").Select(s=>s.Parent).Remove();
 xmlPage.Save("../../xm1.xml");

XMLHelper

因为你指定了xml节点的namespace,查找稍微复杂一点

            var doc = new XmlDocument();
            doc.Load(@"c:\1.xml");
            var nsMgr = new XmlNamespaceManager(doc.NameTable);
            nsMgr.AddNamespace("bg", "bagsinfo");
            var node = doc.DocumentElement.SelectSingleNode("bg:equinfo[bg:Sid=37]", nsMgr);
            if (node != null)
            {
                doc.DocumentElement.RemoveChild(node);
            }
            doc.Save(@"c:\2.xml");

[claymore1114]

 XNamespace xn = "bagsinfo";
 XElement xmlPage = XElement.Load("路径");
 xmlPage.Descendants(xn + "Sid").Where(s => s.Value == "37").Remove();
//是删除 sid节点，还是 连父节点 也删除
//.Where(s => s.Value == "37").Select(s=>s.Parent).Remove()
 xmlPage.Save("路径");
