Help:RuntimeException:Path too complex for xmlbeans

[Guofeng Zhang]

Hi,   I use easypo sample to study how to use XPath to select XML according to the instruction in conSelectingXMLwithXQueryPathXPath.html.   The following codes works well:         String xqNamespace =             "declare namespace po='http://openuri.org/easypo';";         ...         cursor.selectPath( xqNamespace + "$this//po:shipper");   But the following query failed:         cursor.selectPath( xqNamespace + "$this//po:[EMAIL PROTECTED]'ss']"); It throws: java.lang.RuntimeException: Path too complex for xmlbeans: declare namespace po='http://openuri.org/easypo';$this//po:[EMAIL PROTECTED]'ss']   I do not know what is wrong with the above code. Thanks for your help.   Guofeng
