Question

I was provided an XSD file to fill in a value in XML i am generating for submitting to a web service.

The XSD defines values for Enumerations that contain annotations and other info. Best way to describe is to show some of the XSD.

<?xml version="1.0" encoding="utf-16" ?> 
  <xs:schema xmlns="http://MyCompany/Schemas" xmlns:b="http://schemas.microsoft.com/BizTalk   /2003" elementFormDefault="qualified" targetNamespace="http://MyCompany/Schemas" id="NAICSTypes" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:simpleType name="NAICSType">
    <xs:restriction base="xs:int">
      <xs:enumeration value="111110">
        <xs:annotation>
          <xs:appinfo>2007 NAICS Title</xs:appinfo> 
          <xs:documentation xml:lang="en-us">Soybean Farming</xs:documentation> 
        </xs:annotation>
     </xs:enumeration>
     <xs:enumeration value="111120">
       <xs:annotation>
          <xs:appinfo>2007 NAICS Title</xs:appinfo> 
          <xs:documentation xml:lang="en-us">Oilseed (except Soybean) Farming</xs:documentation> 
       </xs:annotation>
     </xs:enumeration>
     <xs:enumeration value="111130">
       <xs:annotation>
          <xs:appinfo>2007 NAICS Title</xs:appinfo> 
          <xs:documentation xml:lang="en-us">Dry Pea and Bean Farming</xs:documentation> 
       </xs:annotation>
     </xs:enumeration>
     <xs:enumeration value="111140">
       <xs:annotation>
         <xs:appinfo>2007 NAICS Title</xs:appinfo> 
         <xs:documentation xml:lang="en-us">Wheat Farming</xs:documentation> 
      </xs:annotation>
     </xs:enumeration>
     <xs:enumeration value="111150">
      <xs:annotation>
         <xs:appinfo>2007 NAICS Title</xs:appinfo> 
         <xs:documentation xml:lang="en-us">Corn Farming</xs:documentation> 
      </xs:annotation>
     </xs:enumeration>

Essentially, what i need to do is provide a value, like 111150, and get back “Corn Farming” as a result in c#

Any Suggestions?

To just query the XML you can use SelectNodes or SelectSingleNode. You’ll also need to specify a namespace manager to the query.

Something like this:

XmlNamespaceManager nsMgr = new XmlNamespaceManager();
nsMgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
string value =
    doc.SelectSingleNode("//xs:enumeration[@value='111150']//xs:documentation", nsMgr
    ).InnerText;
