Question

This is a part of a complex xml template which i put here for the question :

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

<Document>

    <CstmrDrctDbtInitn>

        <GrpHdr>

            <MsgId>${MsgId}</MsgId>

            <CreDtTm>${CreDtTm}</CreDtTm>

            <NbOfTxs>${NbOfTxs}</NbOfTxs>

            <a> ${val1}

              <b>

                ${val2}

              </b>

            </a>

            <CtrlSum>${CtrlSum}</CtrlSum>

        </GrpHdr>

        <PmtInf>

I have been using FreeMarker for the previous month and until now the xml models have been easy

Searching over the web on how to approach this template , should i create matching java classes (100 of them ? )... should i use Map? like shown here .

I don't have a clue how to do it ... how to apply FreeMarker on this template ?

@ddekany The format is xml , the data is created by us . Consider all the data as String . You are right i missed adding these info :) — 12 hours ago
If you have lot of data in a certain format, you don't have to re-wrap it into hand-made classes. Instead write some generic code that converts them to nested Map-s/List-s, and pass that to the template. Or, since the data is XML, you can directly expose it to template as W3C DOM, since FreeMarker knows how to access that. Last not least, you can extend DefaultObjectWrapper and do whatever magic is needed to expose (even load on demand) your data to templates. — 2 hours ago

So here is a solution for any future users . Firstly i created 3 models which i am calling like below :

    Map<String, Object> data = new HashMap<>();





    //================= Example Creating HeaderVo //=================



    HeaderVo header = new HeaderVo("la","la",5,5,"la","la");

    data.put("header", header);



    //================= Example Creating MiddleVo //=================



    MiddleVo middleVo = new MiddleVo("la","la",5,"la","la","la","la");

    data.put("middle", middleVo);



    //================= Example Creating internal items =================





    InternalVo v1 = new InternalVo(5, 5, 5, "s", true, "zz", "zzzz", "ll","EUR");

    InternalVo v2 = new InternalVo(5, 5, 5, "s", true, "zz", "zzzz", "ll","DOLLARS");

    InternalVo v3 = new InternalVo(5, 5, 5, "s", true, "zz", "zzzz", "ll","LAT");





    //List parsing 

    List<InternalVo> internalVos = new ArrayList<>();

    internalVos.add(v1);

    internalVos.add(v2);

    internalVos.add(v3);

    data.put("vos", internalVos);



    //================= //=================  //=================   //=================
