Finding xsd element using attribute value

Question

How can i find complexType element knowing it's name(station)? I'm beginner Here is an entire xsd code: http://pastebin.com/ymuPDCCb This doesn't work.

private XElement GetComplexType(string typeName)
{
    XElement complexType = xsdSchema.Elements("complexType")
        .Where(a => a.Attributes("name").FirstOrDefault() != null && a.Attribute("name").Value==typeName)
        .FirstOrDefault();

    return complexType;
}

You have to include the xs namespace and you need to query all levels using Descendants() instead of Elements(), like so:

private static void ParseXml()
{
    XDocument doc = XDocument.Load(@"C:\schema.xml");

    if (doc != null)
    {
        XElement nodes = GetComplexType("station", doc);

        if (nodes != null)
        {
            Console.WriteLine("station found...");
        }
        else
        {
            Console.WriteLine("station NOT found!!");
        }
    }
}

private static XElement GetComplexType(string typeName, XDocument xsdSchema)
{
    XNamespace ns = "http://www.w3.org/2001/XMLSchema";
    XElement complexType = xsdSchema.Descendants(ns + "complexType")
        .Where(a => a.Attributes("name").FirstOrDefault() != null && a.Attribute("name").Value == typeName)
        .FirstOrDefault();

    return complexType;
}

it still returns null, so there must be some other problems – Alen Kopic May 06 '14 at 13:36
still doesn't resolve my problem of finding nodes by its attribute value – Alen Kopic May 06 '14 at 13:50
Can you post the complete XSD? – Reinder Wit May 06 '14 at 13:52
there you go, i posted complete xsd – Alen Kopic May 06 '14 at 14:24
thx. How are you instantiating the 'xsdSchema' object? I have no problem retrieving the complexType node from the schema XML using the code above... – Reinder Wit May 06 '14 at 14:32
XDocument xsdSchema; xsdSchema = XDocument.Load(filePath); (and typeName=="station") – Alen Kopic May 06 '14 at 14:42
I've put my complete sample in the answer. The code above successfully finds a 'complexType' node with name 'station' on my side... – Reinder Wit May 07 '14 at 06:22
