why does the IE or google chrome does not throw error if the xml file does not follow the xmlschema?

[Guy Emerson]

Hi all,

There is a little confusion as to why does the IE or google chrome does not throw error if the xml file does not follow the xmlschema? let me cite an example:----

country.xsd

<xs:schema   xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="country">

<xs:complexType>
<xs:sequence>
     <xs:element name="state" minOccurs="1" maxOccurs="1">

         <xs:complexType>
          <xs:sequence>

		<xs:element name="capital" type="xs:string" minOccurs="1" maxOccurs="1"/>
		<xs:element name="CM" type="xs:string" minOccurs="1" maxOccurs="1"/>

          </xs:sequence>

	 </xs:complexType>

     </xs:element>



</xs:sequence>
</xs:complexType>
</xs:element>

</xs:schema>

The xml document generated based on this schema is as follows:---


country.xml

<?xml version="1.0"  ?>


<country xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="country.xsd">

<state>
<capital>Guwahati</capital>
<CM>T gogoi</CM>

</state>

<state>
<capital>Guwahati</capital>
<CM>T gogoi</CM>

</state>
<state>
<capital>Guwahati</capital>
<CM>T gogoi</CM>
<CM>rajj</CM>

</state>




</country>

The xml document is not following the rules prescribed but still the browser does not show any error. Why?? It should have shown some error that the xml document does not follow the ruled defined in the schema.

Could you please clarify??

regards

Guy

What makes you think that the browser will bother validating the XML?

[William Brogden]

Browsers are notorious for trying to render incorrect HTML so you should not be surprised that they also try to cope with XML that way.
