java - XML Schema for collection or array containing basic parameters along with other collections or arrays -


i need write xml schema allow production of xml file needs in specific format. hope use , xml schema along jaxb create data object, write data object, , marshal data object correctly formed xml.

unfortunately, there not exist schema xml document, being read legacy code in manual way. goal create xml schema allow jaxb marshal in specific way.

i having problem named collections or arrays. have few variation on , complicated version below.

note have no control on target desired format of xml, need discover how dictate schema produce this. , suggestions very, helpful , promise, xml schema experts, if helps me absolute favorite person of week!

here target format this: 

 <betainfo name="beta id" value="1">       <simplebetainfo>          <param name="simple beta a" value="beta id 1, param data"/>          <param name="simple beta b" value="beta id 1, param b data"/>       </simplebetainfo>       <listbetainfo name="list id" value="1">          <param name="item 1" value="beta id 1, list index 1, item 1 data"/>          <param name="item 2" value="beta id 1, list index 1, item 2 data"/>       </listbetainfo>       <listbetainfo name="list id" value="2">          <param name="item 1" value="beta id 1, list index 2, item 1 data"/>          <param name="item 2" value="beta id 1, list index 2, item 2 data"/>       </listbetainfo>  </betainfo>

this might starting point. describes structure of instance provided, , can adjust support occurrences of child elements.

<?xml version="1.0" encoding="utf-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/xmlschema" elementformdefault="qualified">       <xs:attributegroup name="commonattributes">         <xs:attribute name="name"  type="xs:string"/>         <xs:attribute name="value" type="xs:string"/>     </xs:attributegroup>      <xs:element name="betainfo">         <xs:complextype>             <xs:sequence>                 <xs:element name="simplebetainfo" type="betainfotype" minoccurs="1" maxoccurs="1" />                 <xs:element name="listbetainfo"   type="betainfotype" minoccurs="1" maxoccurs="unbounded"/>             </xs:sequence>             <xs:attributegroup ref="commonattributes"/>         </xs:complextype>     </xs:element>      <xs:complextype name="betainfotype">         <xs:sequence>             <xs:element name="param" minoccurs="2" maxoccurs="2">                 <xs:complextype>                     <xs:attributegroup ref="commonattributes"/>                 </xs:complextype>             </xs:element>         </xs:sequence>         <xs:attributegroup ref="commonattributes"/>     </xs:complextype>  </xs:schema>

the above schema not, however, restrict structure of contents of attributes done using regular expressions, nor relationships between data in different fields (which require xsd 1.1 not supported in jaxb).
