XDocument deleting a node

Question

How do I delete a specific node from a loaded XDocument? My XML document looks like this:

<Snippets>
  <Snippet name="if">
    <SnippetCode>      
 if (condition)
 {
 }
    </SnippetCode>
</Snippet>

<Snippets>
  <Snippet name="foreach">
    <SnippetCode>      
 ...
    </SnippetCode>
</Snippet>

....

</Snippets>

So say if I wanted to delete just the foreach snippet, how would I do that? I tried doc.Descendants.Remove(), but it didn't work for me (the node didn't get deleted).

Edit - on that note, how can I also rename the snippet and edit the snippets through code? I haven't looked into that yet but some help would be appreciated.

Answer 1

untested, but this should work. Let me know if you want it explained.

xdoc.Descendents("Snippet").Where(xe => xe.Attribute("name") != null 
    && xe.Attribute("name").Value == "foreach").Single().Remove()

You can do it simply, at last you should Save file:

       XDocument doc = XDocument.Load("XmlFile1.xml");
        doc.Descendants("Snippet").Where(p => p.Attribute("name") != null 
                                        && p.Attribute("name").Value == "foreach")
                                        .Remove();
        doc.Save("XmlFile1.xml");
