Hi, I read in the Basex-Archive about a bug in xquery:eval, is this related to this bug? list() .... stockdevel_stock_work_COUTRY 122 34188 ... Here is my xquery, it is okay for a small selection size: XQUERY let $xquery := "db:open('stockdevel_stock_work_COUTRY')/*[@n='NZ']" for $i in xquery:eval($xquery) return $i <COUTRY n="NZ" s="valid" t="2013-03-04T22:10:29.308+0100" v="1"> <COUNTRY>Neuseeland</COUNTRY> <REGION>REGION EM</REGION> </COUTRY> if the selection size is greater then about 100: XQUERY let $xquery := "db:open('stockdevel_stock_work_COUTRY')/*" for $i in xquery:eval($xquery) return $i .... <COUTRY n="NZ" s="valid" t="2013-03-04T�����������������" v="1"> <COUNTRY>Neuseeland</COUNTRY> <REGION>REGION EM</REGION> </COUTRY> ..... Sometimes I get : Improper use? Potential bug?
