我正在使用 wso2esb 4.7.0 和 wso2dss3.0.1 我正在获取正确的数据但无法发送到客户端。问题是无法转换消息我的消息显示错误本地条目是 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>>
<eno>
<xsl:value-of select="eno"/>
</eno>
</tr>
</f:for-each>
</xsl:stylesheet>
<description/>
</localEntry>
xslt 配置是这样的
<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>
但我希望向客户端显示数组数据格式我像这样从 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>
并且我的 esb 日志正在评估控制台中的许多错误，它有时会显示 xpath 错误 name=null 是否可以制作我的数据数组
