Selecting nodes with XPath for binding a subset of classes with JAXB
I had the same problem. I found out there was a multiple attribute that was used by XJC to allow multiple node match.
I also wanted the binding to apply to every schema locations. xs:anyURI did not work but I found a way to do it using the * token. I added the required="false" attribute in order to ignore schemas that does not contain any match.
<jxb:bindings schemaLocation="*"> <jxb:bindings node="//xs:complexType[substring(name(), string-length(name()) - 12) = 'Notification']" multiple="true" required="false"> <inheritance:implements>com.google.checkout.sdk.notifications.Notification</inheritance:implements> </jxb:bindings></jxb:bindings>Edit: I posted this answer without reading the comments of the question. Sorry for that. I'm using maven plugin org.codehaus.mojo:jaxb2-maven-plugin:1.5 with XJC plugin org.jvnet.jaxb2_commons:jaxb2-basics-project:0.6.4 and it seems to work like this...
With the
//xs:complexType[substring(name(), string-length(name()) - 12) = 'Notification']expression you're asking for all elements where the element name ends in 'Notification'. You really want to ask for all elements with a name attribute that ends in 'Notification'.
Try this instead:
//xs:complexType[substring(@name, string-length(@name)-string-length("Notification")+1)="Notification"]
I end up with a similar problem "too many target nodes(3)" however could not find any answer on any of the sites...Posting the solution which I found after lots of trail and error...Basic idea to solve "too many target nodes(3)" is to give complete XPATH of the node which is multiple in your XSD.
Below is my XSD:
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="document"> <xs:complexType> <xs:sequence> <xs:element name="asset"> <xs:complexType> <xs:sequence> <xs:element name="attribute" maxOccurs="unbounded" minOccurs="0"> <xs:complexType> <xs:sequence> <xs:element name="string" minOccurs="0"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute type="xs:string" name="value" use="optional"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element name="date" minOccurs="0"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute type="xs:string" name="value" use="optional"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element name="array" minOccurs="0"> <xs:complexType> <xs:sequence> <xs:element name="struct" maxOccurs="unbounded" minOccurs="0"> <xs:complexType> <xs:sequence> <xs:element name="field" maxOccurs="unbounded" minOccurs="0"> <xs:complexType> <xs:sequence> <xs:element name="integer" minOccurs="0"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute type="xs:byte" name="value"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element name="assetreference" minOccurs="0"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute type="xs:string" name="type"/> <xs:attribute type="xs:long" name="value"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute type="xs:string" name="name" use="optional"/> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="integer" minOccurs="0"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute type="xs:long" name="value"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="file" minOccurs="0"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute type="xs:string" name="name" use="optional"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element name="integer" minOccurs="0"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute type="xs:short" name="value"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute type="xs:string" name="name" use="optional"/> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute type="xs:long" name="id"/> <xs:attribute type="xs:string" name="type"/> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element></xs:schema>and below is the JAXB binding file which is working for above XSD:
