如何在使用Record Loader加載數據時更改元素名稱？

Question

我有以下XML： -

<?xml version="1.0" encoding="UTF-8"?> 
<patent-assignment> 
    <assignment-record> 
    <correspondent> 
     <name>NORTH AMERICA INTERNATIONAL PATENT OFFIC</name> 
     <address-1>P.O. BOX 506</address-1> 
     <address-2>MERRIFIELD, VA 22116</address-2> 
    </correspondent> 
    </assignment-record> 
    <patent-assignors>

現在，在加載文件的時間爲Marklogic我想改變專利轉讓的元素名稱來轉讓，名稱和專利代理人的元素名稱受讓人 - 名字，但我想要使用Record Loader加載數據而不是使用Marklogic的Information Studio。我如何使用Record Loader來做到這一點？

Answer 1

您需要設置CONTENT_FACTORY_CLASSNAME=com.marklogic.recordloader.xcc.XccModuleContentFactory並編寫一個XQuery模塊來實現內容模塊。在http://marklogic.github.com/recordloader/有一個示例模塊，您可以自定義該模塊。您的變換代碼將在local:do()函數中執行，取代示例中的「小寫元素本地名」代碼：

xquery version "1.0-ml"; 

declare variable $URI as xs:string external; 
declare variable $XML-STRING as xs:string external; 
declare variable $NAMESPACE as xs:string external; 
declare variable $LANGUAGE as xs:string external; 
declare variable $ROLES-EXECUTE as xs:string external; 
declare variable $ROLES-INSERT as xs:string external; 
declare variable $ROLES-READ as xs:string external; 
declare variable $ROLES-UPDATE as xs:string external; 
declare variable $COLLECTIONS as xs:string external; 
declare variable $SKIP-EXISTING as xs:boolean external; 
declare variable $ERROR-EXISTING as xs:boolean external; 
declare variable $FORESTS as xs:string external; 

declare function local:do($list as node()*) 
as node()* 
{ 
    for $n in $list return typeswitch($n) 
    (: lower-case element localnames :) 
    case element() return element { 
    QName(namespace-uri($n), lower-case(local-name($n))) 
    } { 
    $n/@*, local:do($n/node()) 
    } 
    case document-node() return document { local:do($n/node()) } 
    default return $n 
}; 

if ($SKIP-EXISTING and doc($URI)) then() 
else if ($ERROR-EXISTING and doc($URI)) then error((), 'DUPLICATE-URI', $URI) 
else xdmp:document-insert(
    $URI, 
    local:do(xdmp:unquote(
    $XML-STRING, 
    $NAMESPACE, 
    if ($LANGUAGE) then concat('default-language=', $LANGUAGE) else() 
)), 
    (
    for $r in tokenize($ROLES-EXECUTE, ',')[. ne ''] 
    return xdmp:permission('execute', $r), 
    for $r in tokenize($ROLES-INSERT, ',')[. ne ''] 
    return xdmp:permission('insert', $r), 
    for $r in tokenize($ROLES-READ, ',')[. ne ''] 
    return xdmp:permission('read', $r), 
    for $r in tokenize($ROLES-UPDATE, ',')[. ne ''] 
    return xdmp:permission('update', $r) 
), 
    tokenize($COLLECTIONS, ',')[. ne ''], 
    0, 
    for $id in tokenize($FORESTS, ',')[. ne ''] 
    return xs:unsignedLong($id) 
)
