XML DOM

The XML DOM

The XML DOM (XML Document Object Model) defines a standard way for accessing and manipulating XML documents.

The DOM views XML documents as a tree-structure. All elements can be accessed through the DOM tree. Their content (text and attributes) can be modified or deleted, and new elements can be created. The elements, their text, and their attributes are all known as nodes.

In the examples below we use the following DOM reference to get the text from the element:

xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue

* xmlDoc - the XML document created by the parser.
* getElementsByTagName("to")[0] - the first element
* childNodes[0] - the first child of the element (the text node)
* nodeValue - the value of the node (the text itself)

You can learn more about the XML DOM in our XML DOM tutorial.
The HTML DOM

The HTML DOM (HTML Document Object Model) defines a standard way for accessing and manipulating HTML documents.

All HTML elements can be accessed through the HTML DOM.

In the examples below we use the following DOM reference to change the text of the HTML element where id="to":

document.getElementById("to").innerHTML=

* document - the HTML document
* getElementById("to") - the HTML element where id="to"
* innerHTML - the inner text of the HTML element
