Xslt WSO2 ESB:XSL转换导致WstxUnexpectedCharException

我有一个代理，它需要对来自服务的输出消息进行XSL转换。我已经附加了序列文件和XSL文件（在synaptic configs/local条目中）

如果你能给我一个可能出错的提示，我将不胜感激

以下是序列文件：

<?xml version="1.0" encoding="UTF-8"?>
<sequence xmlns="http://ws.apache.org/ns/synapse" name="EmpMergeOutSeq1" trace="enable" statistics="enable">
    <log level="full">
        <property name="sequence" value="Final Transform using XSLT - begin"/>
    </log>
    <xslt key="getEmployeeByIdResponseXlt"/>
    <send/>
</sequence>

以下是XSL文件：

<?xml version="1.0" encoding="UTF-8"?>
<localEntry xmlns="http://ws.apache.org/ns/synapse" key="getEmployeeByIdResponseXlt">

                    </ax22:id>

                    </ax22:lastName>
                    <ax22:middleName>
                        <xsl:value-of select="ns:return/ax21:middleName"/>
                    </ax22:middleName>

我以前遇到过类似的问题。通常是在XSLT转换期间处理名称空间时。WSO2默认使用xalan.jar作为xml解析器，它被saxon9he.jar替换。以下URL供您参考

谢谢。

谢谢你的帮助！发现了问题。就像你说的，我对XML有问题。非常仔细的检查帮助我找到了它。谢谢你的帮助！发现了问题。就像你说的，我对XML有问题。非常仔细的检查帮助我找到了它。
