I have used the validation facilities of xerces with W3c schemas but I am not familiar with with the API used for reading schemas. I could not find any helpful information from the API documentation. After reading <Source>personal.xsd</Source> schema supplied with Xerces and selecting the root element as <RootElement>personnel</RootElement>. I want to show a tree generated by reading the schema as personnel | +----person | +----(At) id | +---(,) | +----(1) name | +----(1) email | +----(1) link | | | +-----(At) Manager and So on........ Personal.xsd -------------------- <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema'> <xs:element name="personnel"> <xs:complexType> <xs:sequence> <xs:element ref="person" minOccurs='1' maxOccurs='unbounded'/> </xs:sequence> </xs:complexType> <xs:unique name="unique1"> <xs:selector xpath="person"/> <xs:field xpath="name/given"/> <xs:field xpath="name/family"/> </xs:unique> <xs:key name='empid'> <xs:selector xpath="person"/> <xs:field xpath="@id"/> </xs:key> <xs:keyref name="keyref1" refer='empid'> <xs:selector xpath="person"/> <xs:field xpath="link/@manager"/> </xs:keyref> </xs:element> <xs:element name="person"> <xs:complexType> <xs:sequence> <xs:element ref="name"/> <xs:element ref="email" minOccurs='0' maxOccurs='unbounded'/> <xs:element ref="url" minOccurs='0' maxOccurs='unbounded'/> <xs:element ref="link" minOccurs='0' maxOccurs='1'/> </xs:sequence> <xs:attribute name="id" type="xs:ID" use='required'/> <xs:attribute name="note" type="xs:string"/> <xs:attribute name="contr" default="false"> <xs:simpleType> <xs:restriction base = "xs:string"> <xs:enumeration value="true"/> <xs:enumeration value="false"/> </xs:restriction> </xs:simpleType> </xs:attribute> <xs:attribute name="salary" type="xs:integer"/> </xs:complexType> </xs:element> <xs:element name="name"> <xs:complexType> <xs:all> <xs:element ref="family"/> <xs:element ref="given"/> </xs:all> </xs:complexType> </xs:element> <xs:element name="family" type='xs:string'/> <xs:element name="given" type='xs:string'/> <xs:element name="email" type='xs:string'/> <xs:element name="url"> <xs:complexType> <xs:attribute name="href" type="xs:string" default="http://"/> </xs:complexType> </xs:element> <xs:element name="link"> <xs:complexType> <xs:attribute name="manager" type="xs:IDREF"/> <xs:attribute name="subordinates" type="xs:IDREFS"/> </xs:complexType> </xs:element> <xs:notation name='gif' public='-//APP/Photoshop/4.0' system='photoshop.exe'/> </xs:schema> Any insight into this would be of great help.
