Hi Stylussees,


I am searching for a way to cross reference two xml files. My first file contains a list of payment/receipt request which all have a link to a project. My second file contains all projects.

The first file is imported after the second and if a payment/receipt is imported for a project which does not exist the import application returns an error.

What I want to do is cross reference the two xml files to check for projects which do not exist in file 2. So I made below xquery. Which either is not completey correct, cause it runs for hours without any result or my files are just too big - file 1 has 8525 records and file 2 2 has 20.000+ records.

Hope you can help me out,


Cynthia

for $ProjectNumber in doc('file:///e:/Klanten/Conversie/BetalingenOntvangsten/CrossReference/OnlyProjects.xml')/Projects/ProjectNumber return
let $arg1:=$ProjectNumber/text()
for $Project in doc('file:///e:/Klanten/Conversie/Projecten/5maart/AllProjectsOnly.xml')/Projects/Project return
let $arg2:=$Project/text()

return

if ($arg1=$arg2)
then ()
else
<Project>
{$arg1}
</Project>

The following assumes that "ProjectNumber" from document 1 and "Project" from document 2 are the keys for testing your criteria


declare variable $OnlyProjects := doc('file:///e:/Klanten/Conversie/BetalingenOntvangsten/CrossReference/OnlyProjects.xml');
declare variable $AllProjectsOnly := doc('file:///e:/Klanten/Conversie/Projecten/5maart/AllProjectsOnly.xml');


for $ProjectNumber in $OnlyProjects/Projects/ProjectNumber
return
if(exists($AllProjectsOnly/Projects/Project[. = $ProjectNumber])) then ()
else concat("Project ", $ProjectNumber, " missing")

Thanks, I am gonna test it right away....

Posted another problem relating to these files in the XSLT board, cause besides valiation I also want to a separate ProjectMembers xml file into my Projects file. Posted under 'Performance xsl:for each and need for xsl:key instruction?'

Learned a lot this week! Thanks,


Cynthia
