MarkLogic cts的问题：element-values（）

Question

我有20000个文档，每个文档中包含50多个元素。我想要其中一个元素的值，所以这占了20000个值。

＆＃34;问题＆＃34;它们都是相同的值，因为testdata。现在，当我在一个元素上运行cts：element-values（）时，它给了我两个值。这不是我想要的，我希望所有20000都在我的屏幕上。

我添加了范围元素idex，这是搜索所需要的。这是我正在运行的查询。

declare namespace xbrli="http://www.xbrl.org/2003/instance";    
declare namespace venj-bw2-i="http://www.nltaxonomie.nl/nt11/venj/20161214/dictionary/venj-bw2-data";
    let $facts :=
    let $searchNode := "venj-bw2-i:Income"
    let $searchNode2 := "venj-bw2-i:AssetsNoncurrent"
      return cts:element-values(xs:QName($searchNode))

    return $facts

并返回值

300000和310000

使用以下方法添加文档：

for $i in 1 to 20000
return
  xdmp:document-insert(fn:concat("document", $i, ".xml"),

如果我想要那些20000值，你知道我需要运行哪个功能吗？

Answer 1

cts:element-values，cts:values()等类似函数旨在为您返回唯一值，因此您不会返回重复项。您可以使用cts:search()或fn:collection()迭代所有文件，但您也可以根据频率重复这些值，但不确定实际用途是什么。但仍有一些代码：

for $v in cts:element-values(xs:QName("venj-bw2-i:Income"))
for $i in (1 to cts:frequency($v))
return $v

您确定需要像这样重复所有值吗？仅以频率列出值可能就足够了：

for $v in cts:element-values(xs:QName("venj-bw2-i:Income"))
return $v || " - " || cts:frequency($v)

HTH！
