範例
下列範例會建立一個文法,以辨識「已贏得世界盃的國家/地區」片語,後面接著已贏得 World Cup 的國家/地區名稱。 它會建立名為 WorldCupWinner
的公用規則,並將該規則的範圍設定為 [公用]。
// 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;
建立的文法具有下列格式。
<grammar version="1.0" xml:lang="en-US" xmlns="http://www.w3.org/2001/06/grammar" root="WorldCupWinner">
<rule id="WorldCupWinner" scope="public">
<item> A nation that has won the world cup is </item>
<one-of>
<item>
<ruleref uri="#EuropeanNations" />
</item>
<item>
<ruleref uri="#SouthAmericanNations" />
</item>
</one-of>
</rule>
<rule id="EuropeanNations">
<one-of>
<item> England< /item>
<item> France </item>
<item> Germany </item>
<item> Italy </item>
</one-of>
</rule>
<rule id="SouthAmericanNations">
<one-of>
<item> Argentina </item>
<item> Brazil </item>
<item> Uruguay </item>
</one-of>
</rule>
</grammar>
備註
範圍的預設值為 Private
。 私用規則只能由包含文法的根規則參考,或從根規則參考的另一個規則啟用辨識。 除非私用規則宣告為包含文法的根規則,否則外部文法無法參考私人規則。
如果其範圍設定 Public
為 , SrgsRule 則可以從 SrgsRuleRef 包含文法的物件或外部文法中的規則參考啟用物件來辨識物件。
