[Exist-open] XQuery LFWR routine

[Simon K. <ke...@ip...>]

Hi All,

I am just doing some work on xquery LFWR routines to fetch and structure
XML.  But when I try to send this to eXist it throws this error.

org.apache.xmlrpc.XmlRpcException: java.lang.Exception:
org.exist.EXistException: unexpected char: '{'
        at org.apache.xmlrpc.XmlRpcClient$Worker.execute(XmlRpcClient.java)
        at org.apache.xmlrpc.XmlRpcClient.execute(XmlRpcClient.java)
        at
org.katrin.connection.ExistXMLDBConnection.writeQry(ExistXMLDBConnection.jav
a:171)
        at org.katrin.request.XQueryRequest.send(XQueryRequest.java:64)
        at org.katrin.request.XQueryRequest.request(XQueryRequest.java:40)
        at Tester.main(Tester.java:61)

Does eXist implement LFWR or is it only XPath content searches that can be
done.

Regards

Simon

THIS IS THE SEARCH SENT
I borrowed these from another xquery engine just to test it out.

define element bib { (type Book)*}
define type Book {
  element book {
    attribute year {xs:integer},
    element title {xs:string},
    (type Author+ | type Editor+),
    element publisher {xs:string},
    element price {xs:float}
  }
}
define type Author {
  element author {
    element last {xs:string},
    element first {xs:string}
  }
}
define type Editor {
  element editor {
    element last {xs:string},
    element first {xs:string},
    element affiliation {xs:string}
  }
}
define element reviews { type BookR*}
define type BookR {
  element entry {
    element title {xs:string},
    element price {xs:float},
    element review {xs:string}
  }
}
let $bib := validate as element bib (document("data/xmp-data.xml")/bib),
    $review := validate as element reviews
(document("data/Q5xmp-data.xml")/reviews)
for $b in $bib/book,
    $r in $review/entry
  where $b/title = $r/title
  return
     <book>
        {
         $b/title,
         $b/author,
         $r/review
        }
     </book>
