Как использовать медиатор XSLT в wso2esb

Question

Я использую wso2esb 4.7.0 и wso2dss3.0.1 Я получаю данные правильно, но не могу отправить клиенту. Вопрос не в состоянии преобразовать сообщение мое сообщение с указанием ошибки локальные записи являются XSLT-файл

<?xml version="1.0" encoding="UTF-8"?> 
    <localEntry xmlns="http://ws.apache.org/ns/synapse" key="emp_xslt"> 
     <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
         xmlns:f="http://ws.wso2.org/dataservice" 
         version="1.0"> 
      <xsl:output method="xml"/> 
      <xsl:param name="eage"/> 
      <xsl:param name="eno"/> 
      <xsl:template match="/"> 
      <xsl:apply-templates select="/f:empCollection"/> 
      </xsl:template> 
      <f:for-each select="//f:emp"> 
      <tr> 
       <eage> 
        <xsl:value-of select="eage"/> 
       </eage>&gt; 
       <eno> 
        <xsl:value-of select="eno"/> 
       </eno> 
      </tr> 
      </f:for-each> 
     </xsl:stylesheet> 
     <description/> 
</localEntry> 

и XSLT конфигурации, как это

<sequence xmlns="http://ws.apache.org/ns/synapse" name="emp2"> 
    <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:s="http://ws.wso2.org/dataservice" name="eno" expression="//s:empCollection/s:emp/s:eno" scope="default" type="STRING"/> 
    <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:s="http://ws.wso2.org/dataservice" name="eage" expression="//s:empCollection/s:emp/s:eage" scope="default" type="STRING"/> 
    <log level="full"> 
     <property name="response" value="not working"/> 
     <property xmlns:ns="http://org.apache.synapse/xsd" name="eno" expression="get-property('eno')"/> 
     <property xmlns:ns="http://org.apache.synapse/xsd" name="eage" expression="get-property('eage')"/> 
    </log> 
    <xslt xmlns:f="http://ws.wso2.org/dataservice" xmlns:ns="http://org.apache.synapse/xsd" key="emp_xslt" source="/f:empCollection/f:emp"> 
     <property name="eno" expression="get-property('eno')"/> 
     <property name="eage" expression="get-property('eage')"/> 
    </xslt> 
    <log level="full"/> 
</sequence> 

, но я хочу Disply формат данных массива для клиента я получаю данные ESB как этот

Envelope: <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><empCollection xmlns="http://ws.wso2.org/dataservice"><emp><ename>faisal</ename><eno>5</eno><eage>26</eage></emp><emp><ename>suresh</ename><eno>6</eno><eage>26</eage></emp><emp><ename>prashant</ename><eno>7</eno><eage>28</eage></emp><emp><ename>anil</ename><eno>2</eno><eage>27</eage></emp><emp><ename xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/><eno>0</eno><eage>0</eage></emp><emp><ename>-1</ename><eno>0</eno><eage>0</eage></emp></empCollection></soapenv:Body></soapenv:Envelope> 

и мой журнал ESB является evaluting много ошибок в консоли он, показывая ошибку XPATH некоторое время имя = нуль можно ли мак е массив моих данных

Answer 1

Поскольку певце нужны все элементы EMP внутри XSLT медиатора, удалить атрибут источника из посредника XSLT, как показано ниже.

<xslt xmlns:f="http://ws.wso2.org/dataservice" xmlns:ns="http://org.apache.synapse/xsd" key="emp_xslt"> 
     <property name="eno" expression="get-property('eno')"/> 
     <property name="eage" expression="get-property('eage')"/> 
    </xslt>
