Creazione di più nome di un elemento con la sequenza.

Question

Di seguito è riportato il codice XML di esempio che ha <rulex> multipla che inizia con la sequenza 1 e possono finire a molti regola come <rule1> , <rule2>, <rule3> etc ....

<?xml version="1.0" encoding="UTF-8"?>
<AddressChange_181>
    <rules>
        <rule1>
            <conditions>xya</conditions>
            <response_path>abc</response_path>
        </rule1>
        <rule2>
            <conditions>xxxx</conditions>
            <response_path>aaaa</response_path>
        </rule2>
        <rule3>
            <conditions>yyyyy</conditions>
            <response_path>ffff</response_path>
        </rule3>
        <rule4>
            <conditions>zzzz</conditions>
            <response_path>yyyy</response_path>
        </rule4>
        <default>
            <response_path>uuuuu</response_path>
        </default>
    </rules>
</AddressChange_181>

Di seguito è riportato lo schema in cui ho provato la creazione di dinamiche nome dell'elemento <rulex> per l'XML qui sopra. quando ho generare codice XML da questo schema non ho ricevuto lo stesso formato xml come sopra xml. potete per favore fatemelo sapere come creare lo schema con più nome dell'elemento che inizia con un numero di sequenza. La mia esigenza è quella di aggiungere più di una regola (<rule1>,<rule2>,<rule3> ecc ...) in file XML e questo file XML deve essere convalidato contro schema.

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="mock_rule_list"> 
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="rules" minOccurs="1" maxOccurs="1"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

  <xs:element name="rules">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="rule" minOccurs="0" maxOccurs="unbounded"/>        
        <xs:element ref="default" maxOccurs="1"/>
      </xs:sequence>
    </xs:complexType>   
  </xs:element>

  <xs:element name="rule">    
    <xs:complexType>  
    <xs:simpleContent>
      <xs:restriction base="xs:anyType">
        <xs:pattern value="rule/d{1,3}"></xs:pattern>
      </xs:restriction>
    </xs:simpleContent>      
      <xs:sequence>
        <xs:element ref="conditions" minOccurs="1" maxOccurs="1"/>
        <xs:element ref="response_path" minOccurs="1" maxOccurs="1"/>
      </xs:sequence>
    </xs:complexType>   

  </xs:element>

  <xs:element name="default">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="response_path"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="conditions" type="xs:string">   
  </xs:element>
  <xs:element name="response_path" type="xs:string"/>
</xs:schema>

Grazie, Madhu

Non v'è alcun modo per definire una tale struttura utilizzando XSD se il numero di tag ruleX è arbitrariamente definito. Se è possibile vincolare il limite superiore al massimo, e si ha davvero a bastone con ruleX convenzione di denominazione, che si può definire un tipo complesso come RuleType, poi un gruppo di rule1, Regola2, ..., ruleN elementi di quel tipo -. Lo definirei disordinato ... io non consiglierei questo

XSD (con un massimo di 6):

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="mock_rule_list">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="rules" minOccurs="1" maxOccurs="1"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="rules">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="rule1" minOccurs="0"/>
                <xs:element ref="rule2" minOccurs="0"/>
                <xs:element ref="rule3" minOccurs="0"/>
                <xs:element ref="rule4" minOccurs="0"/>
                <xs:element ref="rule5" minOccurs="0"/>
                <xs:element ref="rule6" minOccurs="0"/>
                <xs:element ref="default"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>


    <xs:complexType name="ruleType">
        <xs:sequence>
            <xs:element ref="conditions" minOccurs="1" maxOccurs="1"/>
            <xs:element ref="response_path" minOccurs="1" maxOccurs="1"/>
        </xs:sequence>
    </xs:complexType>

    <xs:element name="default">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="response_path"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="conditions" type="xs:string">
    </xs:element>
    <xs:element name="response_path" type="xs:string"/>

    <xs:element name="rule1" type="ruleType"/>
    <xs:element name="rule2" type="ruleType"/>
    <xs:element name="rule3" type="ruleType"/>
    <xs:element name="rule4" type="ruleType"/>
    <xs:element name="rule5" type="ruleType"/>
    <xs:element name="rule6" type="ruleType"/>
</xs:schema>

In alternativa, si potrebbe avere un tag di nome "regola" con un attributo @sequence.

XSD:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="mock_rule_list">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="rules" minOccurs="1" maxOccurs="1"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="rules">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="rule" minOccurs="0" maxOccurs="unbounded"/>
                <xs:element ref="default"/>
            </xs:sequence>
        </xs:complexType>
        <xs:unique name="SequenceKey">
            <xs:selector xpath="rule"/>
            <xs:field xpath="@sequence"/>
        </xs:unique>
    </xs:element>

    <xs:complexType name="ruleType">
        <xs:sequence>
            <xs:element ref="conditions" minOccurs="1" maxOccurs="1"/>
            <xs:element ref="response_path" minOccurs="1" maxOccurs="1"/>
        </xs:sequence>
        <xs:attribute name="sequence" type="xs:int" use="required"/>
    </xs:complexType>

    <xs:element name="default">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="response_path"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="conditions" type="xs:string">
    </xs:element>
    <xs:element name="response_path" type="xs:string"/>

    <xs:element name="rule" type="ruleType"/>
</xs:schema>

XML di esempio:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<!-- Sample XML generated by QTAssistant (http://www.paschidev.com) -->
<rules xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <rule sequence="1">
        <conditions>conditions1</conditions>
        <response_path>response_path1</response_path>
    </rule>
    <rule sequence="2">
        <conditions>conditions2</conditions>
        <response_path>response_path2</response_path>
    </rule>
    <default>
        <response_path>response_path1</response_path>
    </default>
</rules>

O potrebbe anche essere che si potrebbe usare semplicemente l'indice del all'interno della collezione genitore.
