Question

How can I remove any element in xml based on matched attribute value?

Here is my XML :

<Projects>
    <Project serverUrl="tcp://xyz1:xxx/sdfsdf.rem" projectName="project1" />
    <Project serverUrl="tcp://xyz2:xxx/sdfsdf.rem" projectName="project2" />
    <Project serverUrl="tcp://xyz3:xxx/sdfsdf.rem" projectName="project3" />
    <Project serverUrl="tcp://xyz4:xxx/sdfsdf.rem" projectName="project4" />
    <Project serverUrl="tcp://xyz5:xxx/sdfsdf.rem" projectName="project5" />
    <Project serverUrl="tcp://xyz6:xxx/sdfsdf.rem" projectName="project6" />
   </Projects>

I am using the following LINQ query:

var remove = from elemet in xdoc.Elements("Projects").Elements("Project")
                                 where elemet.Attribute("projectName").Value == "project1"
                                 select elemet.Parent.Remove();

I am getting compile time error on select as :

The type of expression in select
clause is Incorrect

EDIT ANSWER:
this one works for me. Thanks All

var xElement = (from elemet in xdoc.Elements("Projects").Elements("Project")
                            where elemet.Attribute("projectName").Value == foundProject
                            select elemet);
            xElement.Remove();

You can use the following code snippet:

xdoc.XPathSelectElement("Projects/Project[@projectName = 'project1']").Remove();
