Here I am explaining about XML Tree
- First line in XML document known as XML declaration .
- Next line in XML document (<bookstore>) is known as root element of XML document.
- Next line in XML document (<book category="sport">) is known as child element of root element (book store).
- Next four lines in XML document (title, author, year and price) is known as child elements of element book store.
- Next four lines in XML document (</book>) define end of <book category="sport"> element.
- Last line </bookstore> in XML document define end of root element.
XML Documents Form a Tree Structure
XML document must have root element and root element is known as " parent of all elements" in XML document. All element in XML document form a tree structure. This tree start at root element and then sub child of root element.
<root>
<child>
<subchild>.....</subchild>
</child>
</root>
