我的数据包含了一些我需要保密的ID。我想使用带有私钥的散列函数,这样很好。但是当我试图替换内存中的节点时,我无法让它工作。
问题是:我将$values放在mem:node-replace中,但它不是一个节点,我尝试了xdmp:unquote和其他函数,但是它们没有帮助。
在这个示例中,我展示了$values,它是一个很好的“路径”,现在如何将它发送到节点?

在戴夫的博客上阅读和测试之后,这就是我想出来的。不幸的是,它并没有像我预期的那样起作用。代码不会在需要的地方更改元素。
问题是数据的格式给了local:change()函数。这是一份文件,这就是它失败的原因。我认为在我的项目的原始代码中,类型也是一个文档,但是我不能确定,因为xdmp:describe和xdmp:type不工作。

return local:change(document {$doc})发布于 2015-10-19 14:14:22
这是我最后在theGeert的帮助下提出的函数。棘手的部分是case document (),以解决传入数据是文档的问题。
declare function changeid(
$document
){
for $node in $document
let $data :=
typeswitch($node)
(: case on the right cdm:id :)
case element(cdm:id) return
if ($node/parent::cdm:bericht) then
element cdm:id {
hashid($node)
}
else ()
(: root level node :)
case document-node() return
document { $node/node() ! changeid(.) }
(: default case, returns unchanged :)
case element() return
element { fn:node-name($node) } {
$node/@*,
$node/node() ! changeid(.)
}
default return ($node)
return $data
};https://stackoverflow.com/questions/33171663
