Question

我正在创建一个TDE文档，其中我需要从统一文档的标头部分获取数据以及从文档主要部分（工作顺序）获取值。

但是，似乎我当前的tde上下文值未显示预期值。关于我的当前TDE代码中为什么会发生这种情况的任何想法？

我尝试了很多代码，例如以下代码：

// es：headers / ProjectSpecificData / WorkOrderStatusHistory / StatusHistory / StatusHistory

但是它没有从标题中获取任何数据

在FINAL数据库中采样统一文档

当前的TDE文档代码：

xquery version "1.0-ml";
import module namespace tde = "http://marklogic.com/xdmp/tde" 
        at "/MarkLogic/tde.xqy";

let $workordertde:=
<tde:template xmlns:tde="http://marklogic.com/xdmp/tde">

<tde:nullable>true</tde:nullable>
</tde:column>
</tde:columns>
</tde:row>
</tde:rows>
</tde:template>

实际结果：当我为单个文档测试TDE时，它没有显示任何值：

{
"/WorkOrder/JDEdwards/130008HU52-7044389.xml": [
]
}

预期结果：

我希望TDE能够从标头（StatusHistory数据）以及主要部分（WorkOrdercCode）中获得我要获取的值。

编辑：

看起来正在返回状态历史记录值的函数正在返回字符串值。我试图删除toString（）调用，但它不起作用。对代码有什么想法吗？

function getStatusHistory(workOrder) { 
  var status = [];

  let statusHistory =  cts.search(cts.andQuery([
            cts.collectionQuery('Collection1'),
            cts.collectionQuery('Collection2'),
            //cts.collectionQuery('Collection3'),
            cts.elementWordQuery(fn.QName('http://www.testing.com/ads/JDEdwards/wostatushistory', 'F1DOCO'), workOrder)
        ])); 

  if(fn.count(statusHistory) <= 0) return "";

  let builder;
  let doc = new NodeBuilder();
  doc.startElement('StatusHistory');

  for (const item of statusHistory) {

    builder = new NodeBuilder();
    builder.startElement('StatusHistory');

    //Audit
    builder.addElement('UpdatedBy',sfh.ensureStringResult(fn.normalizeSpace(hl.elementText(item, "F1USER", true))));
    builder.addElement('UpdatedDate',sfh.ensureStringResult(fn.normalizeSpace(hl.elementText(item, "F1UPMJ", true))));


    //Status
    let statusCode = fn.normalizeSpace(hl.elementText(item, "F1EWST", true));
    builder.addElement('StatusCode',sfh.ensureStringResult(statusCode));
    builder.addElement('StatusDesc',sfh.ensureStringResult(getUDCDescription("00", "SS", statusCode)));

    builder.addElement('StatusEffectiveDate',sfh.ensureStringResult(fn.replace(fn.normalizeSpace(hl.elementText(item, "F1EFTB", true)),"/","-")));
    builder.addElement('StatusEndDate',sfh.ensureStringResult(fn.replace(fn.normalizeSpace(hl.elementText(item, "F1EFTE", true)),"/","-")));

    builder.endElement();
    doc.addElement('StatusHistory', builder.toNode().xpath('/node()').toString());

  }

  doc.endElement();

  return doc.toNode();
  //return status;
}

ProjectSpecificData元素位于http://testing.com/ads/project命名空间中，但是您没有在上下文路径中引用该命名空间。试试：

<tde:template xmlns:tde="http://marklogic.com/xdmp/tde">
    <tde:context>//es:headers/ads:ProjectSpecificData/fwe:WorkOrderStatusHistory/fwe:StatusHistory/fwe:StatusHistory</tde:context>
    <tde:path-namespaces>
        <tde:path-namespace>
            <tde:prefix>es</tde:prefix>
            <tde:namespace-uri>http://marklogic.com/entity-services</tde:namespace-uri>
        </tde:path-namespace>
        <tde:path-namespace>
            <tde:prefix>ads</tde:prefix>
            <tde:namespace-uri>http://testing.com/ads/project</tde:namespace-uri>
        </tde:path-namespace>
        <tde:path-namespace>
            <tde:prefix>fwe</tde:prefix>
            <tde:namespace-uri>http://testing.com/ads/project/fwe</tde:namespace-uri>
        </tde:path-namespace>
    </tde:path-namespaces>
    ...
