Question

I am having a heck of a time trying to parse a schema file… was hoping someone could help.

Here is what the xsd looks like

 <xs:element name="E1">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="E2" nillable="true" minOccurs="0">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="E3" minOccurs="0" maxOccurs="unbounded">
                            <xs:complexType>
                                <xs:sequence>
                                    <xs:element name="E4" nillable="true" minOccurs="0">
                                        <xs:complexType>
                                            <xs:sequence>
                                                <xs:element name="E5" minOccurs="0" maxOccurs="unbounded">
                                                    <xs:complexType>
                                                        <xs:attribute name="A1" type="xs:integer" use="optional" />
                                                        <xs:attribute name="A2" type="xs:string" use="optional" />
                                                        <xs:attribute name="A3" type="xs:string" use="optional" />\
                                                    </xs:complexType>
                                                </xs:element>
                                            </xs:sequence>
                                        </xs:complexType>
                                    </xs:element>
                               </xs:complexType>
                            </xs:element>
                         </xs:complexType>
                     </xs:element>

This isn’t complete, but enough to get the idea. Here is the code I was trying to get the element name, followed by any attributes if they existed, but this is only returning the element names.

var xs = XNamespace.Get("http://www.w3.org/2001/XMLSchema");
var doc = XDocument.Load(sourceName + sourceApi + "Input.txt");
        foreach (var el in doc.Descendants(xs + "element"))
        {
            Trace.WriteLine("ANDY ------ " + el.Attribute("name").Value);
            foreach (var attr in el.Elements(xs + "attribute"))
            {
                Trace.WriteLine(attr.Attribute("name").Value);
            }
        }

This is outputing

Andy —– E1
Andy —– E2
Andy —– E3
Andy —– E4
Andy —– E5

Where I want it to output

Andy —– E1
Andy —– E2
Andy —– E3
Andy —– E4
Andy —– E5
A1
A2
A3

Thanks in advance.

el.Elements checks only the child elements, so there it return nothing. You should use Descendants or specify full path by el.Elements(xs + "complexType").Elements(xs + "attribute"):

var xs = XNamespace.Get("http://www.w3.org/2001/XMLSchema");
var doc = XDocument.Load(sourceName + sourceApi + "Input.txt");
foreach (var el in doc.Descendants(xs + "element"))
{
    Trace.WriteLine("ANDY ------ " + el.Attribute("name").Value);
    foreach (var attr in el.Elements(xs + "complexType").Elements(xs + "attribute"))
    {
        Trace.WriteLine(attr.Attribute("name").Value);
    }
}
