XML attribute vs XML element

What is the difference between snippet “A”:

<root>
    <item id="1">
        <attr1> foo </attr1>
        <attr2> bar </attr2>
    </item>
</root>

and placing the “id” attribute within the element in snippet “B”:

<root>
    <item>
        <id> 1 </id>
        <attr1> foo </attr1>
        <attr2> bar </attr2>
    </item>
</root>

and how would I add the attribute “id” when creating xml with PHP in snippet “A” assuming I can already create the format of snippet “B” just fine using DOM’s createElement() and appendChild?

Thanks!

Answer 1

“id” is an attribute in snippet “A” and a node in snippet “B”. You can use setAttribute to add this.
