What are some examples of XML namespaces?

XML namespaces are used to avoid element name conflicts. For example, in an XML document, you might have:

<book xmlns:fiction="http://example.com/fiction">
    <fiction:title>The Great Gatsby</fiction:title>
    <fiction:author>F. Scott Fitzgerald</fiction:author>
</book>

Can you explain the purpose of the xmlns attribute?

The xmlns attribute defines a namespace in XML. It helps to distinguish elements that may have the same name but belong to different contexts.

What happens if I don't use namespaces?

Without namespaces, you may encounter naming conflicts, especially in larger XML documents or when combining XML from different sources.

Can you give me another example with different namespaces?

Sure! Here's another example:

<library xmlns:science="http://example.com/science" xmlns:fiction="http://example.com/fiction">
    <science:book>
        <science:title>A Brief History of Time</science:title>
        <science:author>Stephen Hawking</science:author>
    </science:book>
    <fiction:book>
        <fiction:title>1984</fiction:title>
        <fiction:author>George Orwell</fiction:author>
    </fiction:book>
</library>
