Enrich Mediator仅适用于WSO2 ESB 5中的First元素

Question

我正在使用Enrich Mediator丰富的XML.

我的问题是,它总是适用于第一个元素,虽然我想将它应用于多个元素.如何将其应用于XPATH选择的所有元素？

我也试过下面的选项.但失败了.

//Response/ResponseDetails/SearchHotelPriceResponse/HotelDetails/Hotel[@HasExtraInfo="true"]

丰富配置:

<enrich>
    <source type="inline">
        <ImageCode xmlns="">IMG10004</ImageCode>
    </source>
    <target action="child" xpath="//Response/ResponseDetails/SearchHotelPriceResponse/HotelDetails/Hotel[*]"/>
</enrich>

XML有效负载:

<Response ResponseReference="REF_D_028_749-2801486459143247">
    <ResponseDetails Language="en">
        <SearchHotelPriceResponse>
            <HotelDetails>
                <Hotel HasExtraInfo="true" HasMap="true" HasPictures="true">
                    <City Code="LON">London</City>
                    <Item Code="ALE1">ALEXANDRA</Item>
                    <StarRating>3</StarRating>
                    <HotelRooms>
                        <HotelRoom Code="SB" NumberOfRooms="1"/>
                    </HotelRooms>
                </Hotel>
                <Hotel HasExtraInfo="true" HasPictures="true">
                    <City Code="LON">London</City>
                    <Item Code="ALO">Aloft London Excel</Item>
                    <StarRating>4</StarRating>
                    <HotelRooms>
                        <HotelRoom Code="SB" NumberOfRooms="1"/>
                    </HotelRooms>
                </Hotel>
                <Hotel HasExtraInfo="true" HasMap="true" HasPictures="true">
                    <City Code="LON">London</City>
                    <Item Code="AMB3">Ambassadors Bloomsbury</Item>
                    <StarRating>4</StarRating>
                    <HotelRooms>
                        <HotelRoom Code="SB" NumberOfRooms="1"/>
                    </HotelRooms>
                </Hotel>
            </HotelDetails>
        </SearchHotelPriceResponse>
    </ResponseDetails>
