question on xml schema

[greedyisg00d]

Here is my sample schema employee.xsd

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="employee">
 <xs:complexType> 
  <xs:sequence>
   <xs:element name="info">
    <xs:complexType>
     <xs:sequence>
     <xs:element name="lastname" type="xs:string"/>
     <xs:element name="firstname" type="xs:string"/>
	 <xs:element name="middlename" type="xs:string"/>
     <xs:element name="age" type="xs:integer"/>
	 <xs:element name="sex" type="xs:string"/>
	 <xs:element name="position" type="xs:string"/>
     </xs:sequence>
    </xs:complexType>
   </xs:element>
  </xs:sequence>
 </xs:complexType>
</xs:element>
</xs:schema>

next is my sample xml file employee.xml

<?xml version="1.0"?>
<employee>
 <info>
  <lastname>jones</lastname>
  <firstname>daniel</firstname>
  <middlename>warren</middlename>
  <age>25</age>
  <sex>M</sex>
  <position>Manager</position>
 </info>
</employee>

and here is my sample code used to validate my xml based on the schema

$xml = new DOMDocument(); 
$xml->load('./employee.xml');

if (!$xml->schemaValidate('./employee.xsd')) { 
   echo "invalid<p/>";
} 
else { 
   echo "validated<p/>"; 
} 

My problem is it only accepts one record of employee info.
Therefore when a xml file contains 3 records of employee info it prints invalid.
So does it means my schema only accepts 1 record of employee info at a time?
How can I update my schema so it will accept multiple records per employee info?
Thanks

See XML Schema reference, xs:element

w3schools wrote wrote:

maxOccurs
Optional. Specifies the maximum number of times this element can occur in the parent element. The value can be any number >= 0, or if you want to set no limit on the maximum number, use the value "unbounded". Default value is 1. This attribute cannot be used if the parent element is the schema element

The last sentence obviously refers to the fact that there is always one, and only one, root element. This is part of the XML specification and nothing you can circumvent with your schema definition.

Solution: Wrap your employee element in a root element, such as <employees>, and also add maxOccurs="unbounded" for your employee element.
