如何在骡子中检索特定的xml元素

Question

<splitter evaluator="xpath" expression="/productdata/productsList" doc:name="Splitter"/> 
<transformer ref="domToXml" doc:name="Transformer Reference"/> 
<logger level="INFO" doc:name="Logger" message=" productsList...#[message.payload]" />

我输入了如下的 xml 数据。我想显示所有产品名称。上面的代码没有。任何帮助表示赞赏。

<productdata>
     <productsList>
             <product>
                 <productid>100</productid>
                 <productname>handbag</productname>
                 <desc>accessioes</desc>             
            </product>
            <product>
                   <productid>101</productid>
                 <productname>watch</productname>
                 <desc>accessioes</desc>

            </product>     
         </productsList>
         </productdata>

看看xpath3 MEL 函数：http://www.mulesoft.org/documentation/display/current/Mule+Expression+Language+Reference#MuleExpressionLanguageReference-XpathandRegex

或者xpath如果使用Mule版本http://www.mulesoft.org/documentation/display/35X/Mule+Expression+Language+Reference

<splitter expression="#[xpath3('//productsList/product', message.payload, 'NODESET')]" />

<logger level="ERROR" message=" #[xpath3('productname', payload, 'STRING')]" />
