Selezione nodi con XPath per associazione di un sottoinsieme di classi con JAXB

Question

domanda semplificato: Qual è il XPath per selezionare tutti i nodi XML con un attributo che termina con la stringa "Notifica". La prima e la terza nodi in questo frammento:

<events> 
    <event name="CreatedNotification" /> 
    <event name="InfoLog" /> 
    <event name="UpdatedNotification" /> 
</events> 

Domanda dettagliata:

voglio selezionare più complexTypes da uno schema XSD per il legame con JAXB. Questo funziona per una singola classe: OrderStateChangeNotification

<jxb:bindings schemaLocation="apiv2.xsd"> 
    <jxb:bindings node="//xs:complexType[@name='OrderStateChangeNotification']"> 
    <inheritance:implements>com.google.checkout.sdk.notifications.Notification</inheritance:implements> 
    </jxb:bindings> 
</jxb:bindings> 

Ecco il frammento di rilevante dal file di schema di schema:

<xs:complexType name="OrderStateChangeNotification"> 
    <xs:all> 
     <xs:element name="new-fulfillment-order-state" type="tns:FulfillmentOrderState" /> 
     <xs:element name="new-financial-order-state" type="tns:FinancialOrderState" /> 
     <xs:element name="previous-fulfillment-order-state" type="tns:FulfillmentOrderState" /> 
     <xs:element name="previous-financial-order-state" type="tns:FinancialOrderState" /> 
     <xs:element name="reason" type="xs:string" minOccurs="0" /> 
     <xs:element name="timestamp" type="xs:dateTime" /> 
     <xs:element name="google-order-number" type="xs:token" /> 
     <xs:element name="order-summary" type="tns:OrderSummary" minOccurs="0" /> 
    </xs:all> 
    <xs:attribute name="serial-number" type="xs:string" use="required" /> 
    </xs:complexType> 

    <xs:complexType name="ChargeAmountNotification"> 
    <xs:all> 
     <xs:element name="timestamp" type="xs:dateTime" /> 
     <xs:element name="latest-charge-amount" type="tns:Money" /> 
     <xs:element name="latest-charge-fee" type="tns:FeeStructure" minOccurs="0" /> 
     <xs:element name="total-charge-amount" type="tns:Money" /> 
     <xs:element name="latest-promotion-charge-amount" type="tns:Money" minOccurs="0" /> 
     <xs:element name="google-order-number" type="xs:token" /> 
     <xs:element name="order-summary" type="tns:OrderSummary" minOccurs="0" /> 
    </xs:all> 
    <xs:attribute name="serial-number" type="xs:string" use="required" /> 
    </xs:complexType> 

Voglio che il legame di applicare a tutti gli oggetti di notifica. Tutti end con "notifica"

Ho provato a cambiare il XPath da

//xs:complexType[@name='OrderStateChangeNotification'] 

a

//xs:complexType[substring(name(), string-length(name()) - 12) = 'Notification'] 

ma non ha funzionato.

Un altro approccio è provare e selezionare tutti i nodi con "riepilogo dell'ordine" e "numero di serie" per i bambini, poiché so che solo gli oggetti di notifica hanno questi.

UPDATE: La soluzione da @Lee Greco Selectes correttamente i nodi che volevo, ma purtroppo, il plugin eredità non è compatibile con più nodi:

[ERROR] XPath evaluation of "//xs:complexType[substring(@name, string-length(@name)-string-length('Notification')+1)='Notification']" results in too many (8) target nodes 

ho finito per enumerare separatamente.

Answer 1

Con l'espressione

//xs:complexType[substring(name(), string-length(name()) - 12) = 'Notification'] 

stai chiedendo per tutti gli elementi in cui il nome elemento finisce in 'Notifica'. Vuoi davvero chiedere tutti gli elementi con un attributo nome che termina con "Notifica".

Prova a modificare:

//xs:complexType[substring(@name, string-length(@name)-string-length("Notification")+1)="Notification"] 

Answer 2

Ho avuto lo stesso problema. Ho scoperto che esisteva un attributo multiple utilizzato da XJC per consentire la corrispondenza di più nodi.

Desidero anche che il binding venga applicato a tutte le posizioni dello schema. xs:anyURI non ha funzionato, ma ho trovato un modo per farlo usando il token *. Ho aggiunto l'attributo required="false" per ignorare schemi che non contengono alcuna corrispondenza.

<jxb:bindings schemaLocation="*"> 
    <jxb:bindings node="//xs:complexType[substring(name(), string-length(name()) - 12) = 'Notification']" multiple="true" required="false"> 
    <inheritance:implements>com.google.checkout.sdk.notifications.Notification</inheritance:implements> 
    </jxb:bindings> 
</jxb:bindings> 

Edit: Ho postato questa risposta senza leggere i commenti della domanda. Perdonami per quello.Sto usando il plugin Maven org.codehaus.mojo:jaxb2-maven-plugin:1.5 con il plugin XJC org.jvnet.jaxb2_commons:jaxb2-basics-project:0.6.4 e sembra funzionare così ...

Answer 3

Alla fine ho un problema simile "troppi nodi di destinazione (3)" tuttavia non ho trovato nessuna risposta su nessuno dei i siti ... Pubblicando la soluzione che ho trovato dopo un sacco di tracce ed errori ... L'idea di base per risolvere "troppi nodi di destinazione (3)" è dare XPATH completo del nodo che è multiplo nel tuo XSD.

Qui di seguito è il mio XSD:
