One schema for multiple files

[andybeeeeee]

hi, i'm working on a project to make a kind of "universal schema" for a set of xml files and i need some help.

basically what happens is each file has exactly the same elements, but the attributes on one of the elements varies depending on which file it is. e.g.

 <connection cnid="cnAuthorisation" type="QUERY.ScriptingConnection" name="Authorisation" engine="QueryAxScripting.AxScripting" language="JScript">

is in one file and

 <connection cnid="cnAuthorisation" type="QUERYADO.ADOConnection" name="Authorisation" connectionstring="Provider=ADsDSOObject;Data Source=LDAP://EXONY;Mode=Read;Bind Flags=0" />

is in the next.

Is there one way of making my schema work so that i can write in xml code something along the lines of:

  if filename=abc, then attributes here, else if filename=xyz then attributes here...... and so on

appologies if this makes no sense or if i'm talkin utter jibberish, but i'm a java programmer not an xml one. i've been doin xml for 3 days!

thanks in advance

You would write your XSD to make those attributes optional:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema"[/URL] elementFormDefault="qualified" attributeFormDefault="unqualified">
	<xs:element name="Root">
		<xs:complexType>
			<xs:sequence>
				<xs:element name="connection">
					<xs:complexType>
						<xs:attribute name="cnid" type="xs:string" use="required"/>
						<xs:attribute name="type" type="xs:string" use="required"/>
						<xs:attribute name="name" type="xs:string" use="required"/>
						<xs:attribute name="engine" type="xs:string" use="optional"/>
						<xs:attribute name="language" type="xs:string" use="optional"/>
						<xs:attribute name="connectionstring" type="xs:string" use="optional"/>
					</xs:complexType>
				</xs:element>
			</xs:sequence>
		</xs:complexType>
	</xs:element>
</xs:schema>

It would then validate both documents.
