Question

好的，我被要求创建一个新问题，所以这里有。

我想在SOAP请求中提取变量的值

我通过SoapUI向一个骡子流发送SOAP请求

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://sms.csir.co.za/">
 <soapenv:Header/>
 <soapenv:Body>
  <ws:sendTextMessage>
    <sender>Jaco</sender>
    <to>08277899863</to>
    <text>Hallo Jaco how are you</text>
  </ws:sendTextMessage>
 </soapenv:Body>
</soapenv:Envelope>

这是可以正常工作的骡子流。

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

    <flow name="jacoFlow1" doc:name="jacoFlow1">
        <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8090" doc:name="HTTP"/>
        <object-to-string-transformer doc:name="Object to String"/>
        <logger message="#[payload]" level="INFO" doc:name="Logger"/>
    </flow>
</mule>

只要将记录器更改为此值以查找值

 <logger message="#[xpath('//soapenv:Envelope/soapenv:Body/ws:sendTextMessage/text/text()').text]" level="INFO" doc:name="Logger"/>

我收到此错误

Execution of the expression "xpath('//soapenv:Envelope/soapenv:Body/ws:sendTextMessage/text/text()').text" failed. (org.mule.api.expression.ExpressionRuntimeException). Message payload is of type: String

由于XPath表达式使用自定义命名空间（soapenv和ws），因此需要在添加到配置中的表达式管理器元素中声明它们。请参阅：http://www.mulesoft.org/documentation/display/current/XML+Namespaces

<mulexml:namespace-manager>
    <mulexml:namespace prefix="soapenv"
                       uri="http://schemas.xmlsoap.org/soap/envelope/"/>
    ...
</mulexml:namespace-manager>

Mule使用XPath从Payload中返回一个值
