如何在wso2esb中使用XSLT介体

标签： xslt wso2 xslt-2.0 wso2esb wso2dss

我使用的是wso2esb 4.7.0和wso2dss3.0.1 我正在获取数据但无法发送给客户端。该问题无法转换我的邮件显示错误的邮件 本地条目是xslt文件

    <?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>

和xslt配置就像这样

<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>

但我希望显示数组数据格式到客户端我从esb获取数据

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>

我的esb日志在控制台中评估了很多错误它显示了xpath错误一段时间name = null是否可以创建我的数据数组

由于您需要xslt介体中的所有emp元素，因此请从XSLT介体中删除source属性，如下所示。 

<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>
