Hi there, i am trying to use the webservice of an Oracle UCM server to search for a specific document. All i am trying to do is a search in the following pseudosqlcode: Code (Text): WHERE 'dDocTitle' = "testBild4Nagios.png" I can successfully call the AdvancedSearch webservice and perform a search with the following code: Code (Text): $result = $soap->AdvancedSearch(array( 'queryText'=>"" )); That way i get all documents as a search result. Now how do I add the before mentioned WHERE clause? I know that all parameters must be XML encoded, so I tried out: Code (Text): $queryText = 'dDocType <Substring> "testBild4Nagios"'; But I still get the error message: Code (Text): [statusMessage] => The query could not be executed. Invalid character in the query position 9: "dDocType <Substring> "testBild4Nagios"" Position 9 is the first blank in the queryText. I also tried out urlencode to remove the blank character but still no success. Could you help me with this? Do I need to configure the UCM server to accept blank characters? Thanks in advance!
