Removing unwanted nodes from XML, keeping the XML hierarchy same

Removing unwanted nodes from XML, keep the XML hierarchy same

Lets say we have  XML as -
<Hotels>
    <Rooms>
        <name>Standars</name>
        <Type>Deluxe</Type>
        <Rate>123123</Rate>
    <Amenities>sfds</Amenities>
    <Qty>2</Qty>
    </Rooms>
    <Rooms>
        <name>Delux</name>
        <Type>Superior</Type>
        <Rate>453</Rate>
    <Amenities>234</Amenities>
    <Qty>5</Qty>
    </Rooms>
    <Rooms>
        <name>Suite</name>
        <Type>Superior</Type>
        <Rate>3242</Rate>
    <Amenities>xdg</Amenities>
    <Qty>7</Qty>
    </Rooms>
</Hotels>

and we want output as -


<Hotels>
    <Rooms>
        <name>Standars</name>
        <Type>Deluxe</Type>
    </Rooms>
    <Rooms>
        <name>Delux</name>
        <Type>Superior</Type>
    </Rooms>
    <Rooms>
        <name>Suite</name>
        <Type>Superior</Type>
    </Rooms>
</Hotels>      



Below is a linq that can help us to get above result.



var document = XDocument.Load("XMLFile1.xml");
        List<string> removeNames = new List<string> { "Rate", "Amenities", "Qty"}; //Collection of fields to be removed.
        var removeItems = from item in document.Descendants("HotelSummary")
                          let ritems = item.Elements().Where(i => removeNames.IndexOf(i.Name.ToString()) >= 0)
                          select ritems;
      
        foreach (var item in removeItems)
        {
            item.Remove();
        }
        document.Save("d:\\try.xml");
