Example explained: Load the XML string into xmlDoc; Get the child nodes of the root element; For each child node, output the node name and the node value of the text node

XML Tree Structure. XML documents are formed as element trees. An XML tree starts at a root element and branches from the root to child elements. All elements can have sub elements (child elements):

Traversing means looping through or traveling across the node tree. Often you want to loop an XML document, for example: when you want to extract the value of each element. This is called Traversing the node tree. Example of looping through all child nodes of <book>, and displays their names and values: var x, i ,xmlDoc; var txt = "";

Each node in an XML document can be accessed with the DOM. To access a node we can choose any of the below ways: Use the getElementsByTagName () method. Loop through (traversing) the nodes tree. Navigate the node tree, using the node relationships. To get all elements with a specified tag name, the getElementsByTagName () method is used. Syntax:

We can need to loop an XML document in many situations, such as for extracting the value of each element, also known as “Traversing the node tree”. Example: To loop through all the child nodes of <book> and to display their names and values:

With the DOM, you can access every node in an XML document. You can access a node in three ways: getElementsByTagName () returns all elements with a specified tag name. The following example returns all <title> elements under the x element: Note that the example above only returns <title> elements under the x node.

Dec 25, 2024 · What is an XML Tree? An XML document is structured as a tree where each element is a node. The top-level element is called the root node, and all other elements are its descendants. Here is an example of an XML document: This document represents a company with departments, each having employees.

The XML DOM uses a tree-structure, also known as a node-tree, to view an XML document, i.e., each node can be accessed through the tree. We can also modify, delete, or create a new element through the tree. The getElementsByTagName() method and the childNodes property returns a list of nodes.
