我正在使用wso2 esb中的XSLT mediator使用XSLT变换器中介器4.8.1。 的XSLT是：使用WSO2 ESB进行XSLT转换的问题
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fn="http://www.w3.org/2005/02/xpath-functions"
xmlns:ns="http://ep.service.ims.com"
xmlns:ax21="http://ep.service.ims.com/xsd"
exclude-result-prefixes="ns fn">
<xsl:param name="amount"/>
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="//ns:getResponse" />
</xsl:template>
<xsl:template match="ns:getResponse" xmlns:ns="http://ep.service.ims.com">
<ep:credit xmlns:ep="http://ep.service.ims.com" xmlns:xsd="http://ep.service.ims.com/xsd">
<ep:info>
<xsd:amount>
<xsl:value-of select="$amount"/>
</xsd:amount>
<xsd:personInfo>
<xsd:address>
<xsl:value-of select="ns:return/ax21:address"/>
</xsd:address>
<xsd:id>
<xsl:value-of select="ns:return/ax21:id"/>
</xsd:id>
<xsd:name>
<xsl:value-of select="ns:return/ax21:name"/>
</xsd:name>
</xsd:personInfo>
</ep:info>
</ep:credit>
</xsl:template>
</xsl:stylesheet>
，并请求XML是：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns:getResponse xmlns:ns="http://ep.service.ims.com">
<ns:return xsi:type="ax23:PersonInfo" xmlns:ax23="http://ep.service.ims.com/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ax23:address>IMS Heath, Omega C, India, bnag</ax23:address>
<ax23:id>100</ax23:id>
<ax23:name>WSO2</ax23:name>
</ns:return>
</ns:getResponse>
</soapenv:Body>
</soapenv:Envelope>
我试图在Eclipse中XSLT转换和像（http://xslt.online-toolz.com/tools/xslt-transformation.php）一些在线工具，它是工作的罚款。然而，当我试图在WSO2 ESB一样，我对着下面的异常.....
org.apache.synapse.mediators.transform.XSLTMediator} -

突触代理XML是：
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="CreditProxy" transports="https http" startOnLoad="true" trace="disable">
<target>
<inSequence>

</log>

</log>
<xslt key="xslt">

</xslt>

</log>
<property name="STATE" value="CREDIT_REQUEST"/>
<send>

</case>
<case regex="CREDIT_REQUEST">

</log>
<send/>
</case>
</switch>
</outSequence>
</target>
<publishWSDL uri="file:resources/CreditProxy.wsdl"/>
</proxy>
什么可能是例外，如果事业XSLT转换在其他工具中工作正常吗？
您确定错误消息引用了上面显示的XSLT吗？ XPath表达式s11：Body/child :: * [position（）= 1] | s12：Body/child :: * [position（）= 1'在XSLT中找不到。 – 2014-10-08 09:40:14
在你的代理def中，你的xsl的键是'xslt'，但是在你的错误信息中，keyValue是'xslt1'：你如何在ESB中定义这个xsl作为本地条目？你能分享这个本地入口def吗？ – 2014-10-08 10:13:56
