如何根据其属性值删除 XML 元素

Question

I'm having difficulties wrapping my head around how to do this, and since it's my first time doing anything with xml, I figured I should ask more experienced people to save some time.

I know how to remove elements. I've loaded the xml into an XDocument. I know how to read elements, and obtain the value of an attribute of an element. I just don't know how to remove multiple elements of the same type based on the value of their attributes. This is a sample of the XML I want to use. I want to remove all effect elements with type="SetName"

<tech name="Name" type="Normal">
    <displaynameid>11166</displaynameid>
    <effects>
        <effect type="TextOutput"></effect>
        <effect type="Data"></effect>
        <effect type="Data"></effect>
        <effect type="SetName"></effect>
        <effect type="SetName"></effect>
        <effect type="Data"></effect>
        <effect type="SetName"></effect>
        <effect type="SetName"></effect>
        <effect type="SetName"></effect>
    </effects>
</tech>

This is not an answer to your question because your question is too abstract. But since it will be a long comment therefore I am writing it as an answer.

Let's go step by step about your problem.

If you don't know how to read xml in c# then you can read about XElement or XmlReader

If you don't know how to read xml elements then google something like "traversing xml c#"

if you don't know how to read element attributes then XElement has Attributes property which returns a collection of XAttribute which has property Value

if you don't know how to delete child element then see the following link How to delete specific nodes from an XElement?
