好的,我被要求創建一個新問題。Mule使用XPath從有效載荷中返回一個值
我想提取SOAP請求
變量的值通過我發送了SoapUI一個SOAP請求騾子流
<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>
這裏是騾子流工作正常。

只要我改變記錄到這個發現的價值
<logger message="#[xpath('//soapenv:Envelope/soapenv:Body/ws:sendTextMessage/text/text()').text]" level="INFO" doc:name="Logger"/>
我得到這個錯誤
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
這本書。 Mule in Action聲明瞭這個「xpath(xPathExpression)」 - 將XPath表達式應用於正在傳輸的消息 有效負載(必須是XML文檔或DOM實例)。「我試圖將有效負載轉換爲XML和DOM,但得到相同的錯誤。 –
嘗試[this](https://github.com/skjolber/mule-module-dxpath)獲取更高級的XPath表達式 – ThomasRS
