In an XML file such as :
在XML文件中,例如:
<Snippets>
<Snippet name="abc">
<SnippetCode>
code goes here
</SnippetCode>
</Snippet>
<Snippet name="def">
<SnippetCode>
code goes here
</SnippetCode>
</Snippet>
</Snippets>
How can I remove an element when only its attribute name (like abc
or def
) is given?
当只给出其属性名称(如abc或def)时,如何删除元素?

You could try something like this:
你可以尝试这样的事情:
string xmlInput = @"<Snippets>
<Snippet name=""abc"">
<SnippetCode>
code goes here
</SnippetCode>
</Snippet>
<Snippet name=""def"">
<SnippetCode>
code goes here
</SnippetCode>
</Snippet>
</Snippets>";
// create the XML, load the contents
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlInput);
// find a node - here the one with name='abc'
XmlNode node = doc.SelectSingleNode("/Snippets/Snippet[@name='abc']");
// if found....
if (node != null)
{
// get its parent node
XmlNode parent = node.ParentNode;
// remove the child node
parent.RemoveChild(node);
// verify the new XML structure
string newXML = doc.OuterXml;
// save to file or whatever....
doc.Save(@"C:\temp\new.xml");
}

XDocument doc = XDocument.Load("input.xml");
var q = from node in doc.Descendants("Snippet")
let attr = node.Attribute("name")
where attr != null && attr.Value == "abc"
select node;
q.ToList().ForEach(x => x.Remove());
doc.Save("output.xml");

XmlDocument doc = new XmlDocument();
doc.Load("input.xml");
XmlNodeList nodes = doc.SelectNodes("//Snippet[@name='abc']");
Now you have the nodes whose attribute name='abc', you can now loop through it and delete
现在你有了属性名称为'abc'的节点,你现在可以遍历它并删除它
