使用MarkLogic流编辑器拆分文档
使用MarkLogic流编辑器拆分文档
提问于 2015-06-29 20:57:20
我尝试使用"Information Studio Flow“(MarkLogic v8.0-1.1)拆分传入的文档。问题出在“转换”部分。
这是我的导入单据。为简单起见，我将其内容简化为一个stwtext-element
<docs>
<stwtext id="RD-10-00258" update="03.2011" seq="RQ-10-00001">
<head>
<ti>
<i>j</i>
</ti>
<ff-list>
<ff id="0103"/>
</ff-list>
</head><p>
Symbol für die
<vw idref="RD-19-04447">Stromdichte</vw>
.
</p>
</stwtext>
</docs>
这是我的"xquery转换“内容：
xquery version "1.0-ml";

import module namespace cpf = "http://marklogic.com/cpf"
at "/MarkLogic/cpf/cpf.xqy";

declare option xdmp:mapping "false";
declare variable $cpf:document-uri as xs:string external;
declare variable $cpf:transition as node() external;
if ( cpf:check-transition($cpf:document-uri,$cpf:transition))
then
try {
(: START your custom XQuery here :)
let $doc := fn:doc($cpf:document-uri)
return
xdmp:eval(
for $wpt in fn:doc($doc)//stwtext
return
xdmp:document-insert(
fn:concat("/rom-data/", fn:concat($wpt/@id,".xml")),
$wpt
)
)
(: END your custom XQuery here :)
,
cpf:success( $cpf:document-uri, $cpf:transition, () )
}
catch ($e) {
cpf:failure( $cpf:document-uri, $cpf:transition, $e, () )
}
else ()
通过运行代码片段，我接受了以下错误：

我想，这是“流编辑器”的“加载”部分中的“文档设置”的问题。
URI=/content{$path}/{$filename}{$dot-ext}但是如果我删除它，我会收到同样的错误。
我不知道该怎么办。我真的是新来的。请帮帮忙

首先，Information Studio在MarkLogic 8中已被弃用。我还非常推荐研究一下MarkLogic Content Pump的aggregate_record特性：
http://docs.marklogic.com/guide/ingestion/content-pump#id_65814
除此之外，你的代码还有几个问题。您调用了两次fn:doc，有效地尝试将文档内容解释为uri。有一个不必要的xdmp:eval包装FLWOR语句，它需要一个字符串作为第一个参数。我认为您可以将其缩短为(仅显示动作的内部部分)：
(: START your custom XQuery here :)
let $doc := fn:doc($cpf:document-uri)
for $wpt in $doc//stwtext
return
xdmp:document-insert(
fn:concat("/roempp-data/", fn:concat($wpt/@id,".xml")),
$wpt
)
(: END your custom XQuery here :)哈！

非常感谢@grtjn，这就是我的方法。实际上，它是相同的解决方案
(: START your custom XQuery here :)
xdmp:log(fn:doc($cpf:document-uri), "debug"),
let $doc := fn:doc($cpf:document-uri)
return
xdmp:eval('
declare variable $doc external;
for $wpt in $doc//stwtext
return (
xdmp:document-insert(
fn:concat("/roempp-data/", fn:concat($wpt/@id,".xml")),
$wpt,
xdmp:default-permissions(),
"roempp-data"
)
)'
,
(xs:QName("doc"), $doc),
<options xmlns="xdmp:eval">
<database>{xdmp:database("roempp-tutorial")}</database>
</options>
)
(: END your custom XQuery here :)
好了，现在它起作用了。这很好，但是我发现，加载结束后，我在MarkLogic中看到了两个文档：
我的拆分文档“/rom-
- /RD-10-00258.xml”包含一个根元素"stwtext“(作为带有根元素"docs"
的desired)
- origin document "URI=/content/home/admin/Vorlagen/testing/v10.new-ML.xml”
是否可以禁止插入源文档？
