Question

I try to Parse an XML file and collect from it the wanted value. I’ve the following XML:

<?xml version="1.0"?>
<TDXItem>
    <PROJECT_NAME name="Project_MNG_Test">
            <PROJECT_ID>1022</PROJECT_ID>
            <DOMAIN_NAME>PROJECTS_MNG</DOMAIN_NAME>
            <DB_NAME>projects_mng_project_mng_test_</DB_NAME>
    </PROJECT_NAME>
    <PROJECT_NAME name="Project_MNG_Test1">
            <PROJECT_ID>1023</PROJECT_ID>
            <DOMAIN_NAME>PROJECTS_MNG</DOMAIN_NAME>
            <DB_NAME>projects_mng_project_mng_test1_</DB_NAME>
    </PROJECT_NAME>
</TDXItem>

and I tried versious of codes, most recent the below code:

public static void RunQuery(){
            string UserName = null;
            string xmlURI = "Sites_Name.xml";
            XDocument doc = XDocument.Load(xmlURI);
            var field = doc.Descendants("PROJECT_NAME").Where(x => (string)x.Attribute("name") == "PROJECT_MNG_Test").FirstOrDefault();
            if (field != null)
            {
        // Use value here                    
        string value = (string)field.Element("DB_NAME");

             }    
 }

but my value is getting null all the time, I tried a lot of convention noting work.
I know that it’s my bad, but i don’t know where, in my code or at the way I built the XML file.

You shouldn’t specify a namespace here, for example use:

var field = doc.Descendants("PROJECT_NAME")
   .Where(x => (string)x.Attribute("name") == "Project_MNG_Test").FirstOrDefault();
