--- Comment #5 from PJ Fanning <fannin...@yahoo.com> --- I did a test with POI 5.2.3 and I see that some of the XML files inside the xlsx files created by POI can end up with `standalone="no"`. See write-example branch of https://github.com/pjfanning/poi-gradle-example The files I saw with this are: [Content_Types].xml docProps/core.xml _rels/.rels xl/_rels/workbook.xml.rels These files seem to be written using org.apache.poi.openxml4j.opc.StreamHelper. This class uses a javax Transformer and tries to set standalone=yes but it looks like the transformer ignores this. I added 'net.sf.saxon:Saxon-HE:11.6' to the classpath and this means that Saxon provides the Transformer instead of the default Java one being used. With Saxon, the output has standalone=yes. Note that Saxon-HE 12 has changes that mean it doesn't work with POI/XMLBeans. So try adding 'net.sf.saxon:Saxon-HE:11.6' to your classpath and see if that helps in your case. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
