What is an XML Schema and how is it used?

An XML Schema defines the structure, content, and semantics of XML documents. It's used to validate XML data.

Can you give me an example of an XML Schema?

Sure! Here's a simple example:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="note">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="to" type="xs:string"/>
        <xs:element name="from" type="xs:string"/>
        <xs:element name="heading" type="xs:string"/>
        <xs:element name="body" type="xs:string"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

How does XML Schema differ from DTD?

XML Schema is more powerful than DTD as it supports data types, namespaces, and provides better validation capabilities.

Where can I learn more about XML Schema?

You can learn more from the W3C website, online courses, or tutorials on platforms like Codecademy and Coursera.
