David, XMLBeans 2.5.0 supports the same version of Saxon as XMLBeans 2.4.0 does. If you read otherwise, that is a mistake. I expect that the behavior you are seeing will be the same if you use XMLBeans 2.5.0 instead of 2.4.0, with Saxon being constant. It could be a bug in Saxon, given that the NPE occurs in the Saxon code. You could try a newer version of Saxon. As long as Saxon hasn't changed its API (which has been known to happen between dot releases), XMLBeans will still work with it. - Wing Yew

Can I use the latest Saxon 9.2 directly ? Thanks for your answers! David P.S.: Here is the exception I got with xmlBeans and saxon 9: java.lang.NullPointerException at net.sf.saxon.dom.NodeWrapper$ChildEnumeration.skipFollowingTextNodes(NodeWrapper.java:1088) at net.sf.saxon.dom.NodeWrapper$ChildEnumeration.next(NodeWrapper.java:1114) at net.sf.saxon.om.Navigator$AxisFilter.next(Navigator.java:882) at net.sf.saxon.expr.FilterIterator.getNextMatchingItem(FilterIterator.java:61) at net.sf.saxon.expr.FilterIterator.next(FilterIterator.java:44) at net.sf.saxon.expr.ContextMappingIterator.next(ContextMappingIterator.java:54) at net.sf.saxon.expr.ContextMappingIterator.next(ContextMappingIterator.java:51) at net.sf.saxon.value.SequenceExtent.<init>(SequenceExtent.java:98) at net.sf.saxon.sort.DocumentOrderIterator.<init>(DocumentOrderIterator.java:30) at net.sf.saxon.sort.DocumentSorter.iterate(DocumentSorter.java:84) at net.sf.saxon.sxpath.XPathExpression.evaluate(XPathExpression.java:97) at org.apache.xmlbeans.impl.xpath.saxon.XBeansXPath.selectNodes(XBeansXPath.java:119) at org.apache.xmlbeans.impl.xpath.saxon.XBeansXPath.selectPath(XBeansXPath.java:148) at org.apache.xmlbeans.impl.store.Path$DelegatePathImpl$DelegatePathEngine.next(Path.java:541) at org.apache.xmlbeans.impl.store.Cursor._toSelection(Cursor.java:931) at org.apache.xmlbeans.impl.store.Cursor._toNextSelection(Cursor.java:920) at org.apache.xmlbeans.impl.store.Cursor._hasNextSelection(Cursor.java:912) at org.apache.xmlbeans.impl.store.Cursor.hasNextSelection(Cursor.java:2652) at org.apache.xmlbeans.impl.values.XmlObjectBase.selectPath(XmlObjectBase.java:464) at org.apache.xmlbeans.impl.values.XmlObjectBase.selectPath(XmlObjectBase.java:446) at com.qwi.coficio.vp.repository.PageRepositoryImpl.getRegionBlocksForRegion(PageRepositoryImpl.java:153) SaxonB 8.6.1 versions of the saxon8.jar and saxon8-dom.jar
