Example of reading well-formed and valid xml reading using xmlReader

I m looking for some good example of reading a well-formed and valid xml file (having external dtd attached to it) using XmlReader of c#

Have googled it and gone through books but cannot find a good and well explained example.

this is the XML file:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE Catalog SYSTEM "marketplace_feed_v2.dtd">
<Catalog>
<Category>
<Name>Arts &amp; Entertainment</Name>
<Site>
<Id>ABC CORP</Id>
<PopularityRank>1</PopularityRank>
<Title><![CDATA[Some Description]]></Title>
<Description><![CDATA[Don't Have A Website? Create A Money Making Website]]></Description>
<HasRecurringProducts>true</HasRecurringProducts>
<Gravity>432.74</Gravity>
<PercentPerSale>75.0</PercentPerSale>
<PercentPerRebill>45.0</PercentPerRebill>
<AverageEarningsPerSale>28.14599</AverageEarningsPerSale>
<InitialEarningsPerSale>25.3445</InitialEarningsPerSale>
<TotalRebillAmt>28.55413</TotalRebillAmt>
<Referred>95.0</Referred>
<Commission>75</Commission>
<ActivateDate>2009-06-29</ActivateDate>
</Site>
</Categoty>
<Category><Site>....</Site></Category></Catalog>

This is the DTD File:

<!ELEMENT Catalog ( Category* ) >
<!ELEMENT Category ( Name, Site*, Category* ) >
<!ELEMENT Commission ( #PCDATA ) >
<!ELEMENT Description ( #PCDATA ) >
<!ELEMENT InitialEarningsPerSale ( #PCDATA ) >
<!ELEMENT AverageEarningsPerSale ( #PCDATA ) >
<!ELEMENT TotalRebillAmt ( #PCDATA ) >
<!ELEMENT HasRecurringProducts ( #PCDATA ) >
<!ELEMENT Gravity ( #PCDATA ) >
<!ELEMENT Id ( #PCDATA ) >
<!ELEMENT Name ( #PCDATA ) >
<!ELEMENT PercentPerSale ( #PCDATA ) >
<!ELEMENT PercentPerRebill ( #PCDATA ) >
<!ELEMENT PopularityRank ( #PCDATA ) >
<!ELEMENT ActivateDate ( #PCDATA ) >
<!ELEMENT Site ( Commission? | Site+ | InitialEarningsPerSale? | AverageEarningsPerSale? | TotalRebillAmt? | Gravity? | Id+ | PercentPerSale? | PercentPerRebill? | PopularityRank+ | Title+ | HasRecurringProducts | ActivateDate? )* >
<!ELEMENT Title ( #PCDATA ) >

Found that XmlReader is read-only and forward-only. so used this

StreamReader stream = new StreamReader(filePath);
XmlReader reader = XmlReader.Create(stream, settings);
        while (reader.Read())
        {
            reader.MoveToContent();
            // Parse the file and display each of the nodes.
            while (reader.Read())
            {
                reader.MoveToElement();
                if (reader.Name.Equals("Category") && reader.NodeType != XmlNodeType.EndElement)
                {
                    Response.Write("<b>" + reader.Name + "</b>" + "<br/>");
                }
                else if (reader.Name.Equals("Name") && reader.NodeType != XmlNodeType.EndElement)
                {
                    Response.Write("<span style='color:#1884A5'>" + reader.Name + "</span>" + " : ");
                    Response.Write(reader.ReadElementString() + "<br/>");
                }
         }

If any one with better example... i would appreciate..

I would try to give XLINQ, read: LINQ to XML examples and try it out.

It should be very easy, straight forward, and is easily editable.
