Examples

The following example creates an SrgsDocument object, and then creates a public rule named winnerRule. It then creates an SrgsItem that consists of the string "A nation that has won the World Cup is:", and adds this item to the Elements property of the rule. The example then creates two more rules (ruleEurope and ruleSAmerica), each of which is an SrgsOneOf object that contains three SrgsItem objects. After that, another SrgsOneOf object is created that contains SrgsRuleRef objects that refer to ruleEurope and ruleSAmerica. The new SrgsOneOf object is then added to the Elements property of winnerRule. After this, all three rules (winnerRule, ruleEurope, and ruleSAmerica) are added to the Rules property of the SrgsDocument. Finally, the example creates an empty XML file and an instance of XmlWriter. The WriteSrgs method uses the XmlWriter instance to write the contents of the SrgsDocument to the XML file.

public void WorldSoccerWinners ()
{

  // Create an SrgsDocument, create a new rule
  // and set its scope to public.
  SrgsDocument document = new SrgsDocument();
  SrgsRule winnerRule = new SrgsRule("WorldCupWinner");
  winnerRule.Scope = SrgsRuleScope.Public;

  // Add the introduction.
  winnerRule.Elements.Add(new SrgsItem("A nation that has won the World Cup is: "));

  // Create the rule for the European nations.
  SrgsOneOf oneOfEurope = new SrgsOneOf(new SrgsItem[] {new SrgsItem("England"),
    new SrgsItem("France"), new SrgsItem("Germany"), new SrgsItem("Italy")});
  SrgsRule ruleEurope = (new SrgsRule("EuropeanNations", new SrgsElement[] {oneOfEurope}));

  // Create the rule for the South American nations.
  SrgsOneOf oneOfSAmerica = new SrgsOneOf(new SrgsItem[] {new SrgsItem("Argentina"),
    new SrgsItem("Brazil"), new SrgsItem("Uruguay")});
  SrgsRule ruleSAmerica = (new SrgsRule("SouthAmericanNations", new SrgsElement[] {oneOfSAmerica}));

  // Add references to winnerRule for ruleEurope and ruleSAmerica.
  winnerRule.Elements.Add(new SrgsOneOf(new SrgsItem[] {(new SrgsItem
    (new SrgsRuleRef(ruleEurope))), new SrgsItem(new SrgsRuleRef(ruleSAmerica))}));

  // Add all the rules to the document and make winnerRule
  // the root rule of the document.
  document.Rules.Add(new SrgsRule[] {winnerRule, ruleEurope, ruleSAmerica});
  document.Root = winnerRule;

  // Create a string object with the path to the file to use.
  string srgsDocumentFile = Path.Combine(Path.GetTempPath(), "srgsDocumentFile.xml");

  // Create an XmlWriter object and pass the file path.
  XmlWriter writer = XmlWriter.Create(srgsDocumentFile);

  // Write the contents of the XmlWriter object to an SRGS-compatible XML file.
  document.WriteSrgs(writer);
  writer.Close();
