removing nil tags from response
Hello,
I am using XMLBeans 2.2.0 for data binding in my web service; i.e. request
and response.
If for some of the values in my response are null/ nil.. the response tag is
coming as
<Data xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
i don't want these nil value. the "Data" element is defined as
<xsd:element name="Data" type="xsd:string" minOccurs="0"/>
please let me know how can i get rid fo these
Any help is appreciated.
Thanks
Krishna

Hello Jeff,
Thanks for reply..... The code works fine with small correction
.........
cursor.removeXml() ;
cursor.toPrevToken(); // to be added
............
// if the toPrevToken() is not used, it will not remove two consecutive nil
elements.
// because removeXml() will set the cursor to the next available token and
that next token is skipped due to condition in while loop.
Regards,
Krishna

Something like this should work:
XmlCursor cursor = mydoc().newCursor() ;
try {
do {
if( cursor.isStart() && cursor.getObject().isNil() ) {
cursor.removeXml() ;
}
} while( !cursor.toNextToken().isNone() ) ;
}
finally {
cursor.dispose() ;
}
As cursor.removeXml() will remove the element, you may need to
experiment with the loop condition to make it full-proof.
Regards
Jeff
