[MarkLogic Dev General] RE: How to convert a String to element type

[Ashish Kumar]

I found a way to solve this.

 

1.	I set the request query still as string
2.	request.setNewStringVariable("query","<search:ashish>

<search:search-criteria>
<search:term><search:text>cell</search:text><search:element><search:local-na
me>Body</search:local-name></search:element></search:term>
<search-path>/Publisher/PublisherInfo</search-path><sort><sort-field
type=\"xs:string\">PublisherName</sort-field><sort-field-id>ChapterTitle</so
rt-field-id></sort></search:search-criteria>

</search:ashish>");

 

3.	In my xqy file

import module namespace search="http://www.marklogic.com/ps/lib/lib-search"
at "lib-search.xqy"

import module namespace search1="http://www.marklogic.com/ps/lib/lib-search"
at "lib-search-custom.xqy"

 

 define variable $query as xs:string external

let $newQuery := xdmp:unquote($query,"")

return

let $results :=search:search-results($newQuery//search:search-criteria,1,5)

 

 

Thanx.

Ashish

Hi I am evaluating MarkLogic server for our new project. 

I was trying to use lib-search library for searching. 

Following function accepts element.

define function search-results($search-criteria as
element(search:search-criteria), $start as xs:integer, $end as xs:integer)
as node()*

{

  get-search-results(build-search-string($search-criteria,
build-cts-query($search-criteria)), $start, $end)

}

 

We can invoke the same by 


import module namespace search="http://www.marklogic.com/ps/lib/lib-search"
at "lib-search.xqy"


import module namespace search1="http://www.marklogic.com/ps/lib/lib-search"
at "lib-search-custom.xqy"


search:search-results(<search:search-criteria><search:term><search:text>smit
h</search:text></search:term></search:search-criteria>


, 1, 5)


 


Same I was trying to invoke through java xcc library. But I get the
following exception


Exception in thread "main" com.marklogic.xcc.exceptions.XQueryException:
XDMP-AS: search1:search-results("<search:search-criteria>
<search:term><search:text>cell</search:...", 1, 5) -- Invalid coercion:
"<search:search-criteria> <search:term><search:text>cell</search:..." as
element(search:search-criteria)

in /libSearch-SearchSummary1.xqy, on line 5

<search:term><search:text>cell</search:...", 1, 5)

Pointers to the above will be appreciated.


 


Thanx a ton in advance,
