Marklogic Content Pump generate multiple documents through XSLT transform -

this second question related marklogic content pump utility.

i ingesting single aggregated xml document multiple records marklogic content pump. expect the aggregate xml document transformed different format , content pump utility generate multiple xml document single input large xml document.?

example: aggregated input xml document:

<root>  <data>bob</data>  <data>vishal></data> </root> 

expected output content pump : 2 documents different format:

document 1 :

<data1>bob</data1> 

document 2

<data1>vishal</data1> 

i using following xslt split above document 2 nodes:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform"     xmlns:xs="http://www.w3.org/2001/xmlschema"     exclude-result-prefixes="xs"     version="2.0">   <xsl:template match="root">     <xsl:apply-templates select="data"></xsl:apply-templates>   </xsl:template>   <xsl:template match="data">     <data1><xsl:value-of select="."/></data1>   </xsl:template> </xsl:stylesheet> 

output:

<?xml version="1.0" encoding="utf-8"?> <data1>bob</data1> <data1>vishal</data1> 

following xquery transform, calls above "xslt file" generate 2 nodes:

xquery version "1.0-ml"; module namespace example = "http://marklogic.com/example";  declare function example:transform(   $content map:map,   $context map:map ) map:map* {   let $attr-value :=      (map:get($context, "transform_param"), "undefined")[1]   let $the-doc := map:get($content, "value")    let $let-output:=  xdmp:xslt-invoke("/marklogic.rest.transform/simple-xsl/assets/transform.xsl", $the-doc )   return (map:put(           $content, "value",           $let-output         ),$content)  }; 

the above xquery transforms fails , returns error. so, how modify above xquery program generates , indexes multiple transformed xml documents single document?

mlcp command:

mlcp.sh import -host localhost -port 8040 \     -username admin -password admin \     -input_file_path ./parent-form.xml \     -transform_module /example/parent-transform.xqy \     -transform_namespace "http://marklogic.com/example" \     -transform_param "my-value" \     -output_collections people \     -output_permissions my-app-role,read,my-app-role,update  

the transform provided returns single document containing multiple root elements. transform work, marklogic not allow inserting database, , throw xdmp-multiroot: document nodes cannot have multiple roots.

there 2 ways solve that. simplest use /* behind xdmp:xslt-invoke. other solution use <xsl:result-document href="{generate-id()}.xml"> inside xslt. both cause $let-output contain sequence instead of single document.

however, without further changes result in xdmp-conflictingupdates, write multiple results @ 1 database uri. solve can clone $content map:map small trick, , provide separate uris. instance this:

for $let-output @ $i in xdmp:xslt-invoke("/marklogic.rest.transform/simple-xsl/assets/transform.xsl", $the-doc )/* let $extra-content := map:map(document{$content}/*) let $_ := map:put($extra-content, "value", $let-output) let $_ := map:put($extra-content, "uri", concat($the-uri, '-', $i, '.xml') ) return   $extra-content 

note: transform function has return type of map:map*, meaning can return 0 or more map:map's containing result.

hth!
