Enrich调解器仅适用于WSO2 ESB中的第一个元素5
问题描述：
我正在使用Enrich Mediator来丰富XML。Enrich调解器仅适用于WSO2 ESB中的第一个元素5
我的问题是，它总是适用于第一个元素，但我想将其应用于多个元素。我如何将它应用于XPATH选择的所有元素？
我也试过下面的选项。但失败。
//Response/ResponseDetails/SearchHotelPriceResponse/HotelDetails/Hotel[@HasExtraInfo="true"]
富民配置：
<enrich>
<source type="inline">
<ImageCode xmlns="">IMG10004</ImageCode>
</source>
<target action="child" xpath="//Response/ResponseDetails/SearchHotelPriceResponse/HotelDetails/Hotel[*]"/>
</enrich>
XML有效载荷：
<Response ResponseReference="REF_D_028_749-2801486459143247">
<ResponseDetails Language="en">
<SearchHotelPriceResponse>
<HotelDetails>
