如何从一个XML元素中删除所有属性？

Question

I have the following string containing XML:

var mystring = "<?xml version="1.0" encoding="UTF-8"?><?adf version="1.0"?>
<adf>
<example url="https://someurl.com/?id=123&amp;hash=6WHnYZwE" 
anotherurl="https://someurl.com/status?id=123;hash=6WHnYZwE" something="Hi">
    <status>new</status>
    <requestdate>2017-11-15T19:45:23-05:00</requestdate>
    <Apples>
        <color>red</color>
        <origin>Washington</make>
    </Apples>
</example>
</adf>";

I want to remove the attributes from the <example> element so that this

<example url="https://someurl.com/?id=123&amp;hash=6WHnYZwE" anotherurl="https://someurl.com/status?id=123;hash=6WHnYZwE" something="Hi">

becomes this

<example>

I tried using String.Replace to replace the attributes with an empty string, but the attributes aren't always the same. Any help is appreciated!

I'm a little bit rusty with my XML parsing so I'm sure this can be improved.

public void DeleteContentsOfExampleElement()
{
    var mystring = @"<?xml version=""1.0"" encoding=""UTF-8""?><?adf 
version=""1.0""?>  
<adf>  
<example url=""https://someurl.com/?id=123&amp;hash=6WHnYZwE"" 
anotherurl=""https://someurl.com/status?id=123;hash=6WHnYZwE"" 
something=""Hi"">
<status>new</status>  
<requestdate>2017-11-15T19:45:23-05:00</requestdate>
<Apples>
    <color>red</color>
    <origin>Washington</origin>
</Apples>
</example>
</adf>";
    var document = new XmlDocument();
    document.LoadXml(mystring);
    var exampleElements = document.GetElementsByTagName("example");
    foreach (XmlNode exampleElement in exampleElements)
    {
        exampleElement.Attributes?.RemoveAll();
    }
}
