<h2>XML DOM Summary</h2>
<p>The XML DOM defines a standard for accessing and manipulating XML.</p>
<p>According to the DOM, everything in an XML document is a
<a href="dom_nodes.asp">node</a>.</p>
<p>The text of an element node is stored in a <a href="dom_nodes.asp">text node</a>.</p>
<p>The XML DOM views an XML document as a tree-structure. The tree structure is
called a <a href="dom_nodetree.asp">node-tree</a>.</p>
<p>In a node tree, the terms parent, child, and sibling are used to describe the
relationships.</p>
<p>All modern browsers have a build-in <a href="dom_parser.asp">XML parser</a>
that can be used to read and manipulate XML.</p>
<p>With the XML DOM <a href="dom_methods.asp">properties and methods</a>, you
can <a href="dom_nodes_access.asp">access</a> every node in an XML document.</p>
<p>Important node properties: <a href="dom_nodes_info.asp">nodeName, nodeValue,
and nodeType</a>.</p>
<p>When using properties or methods like childNodes or getElementsByTagName(), a
<a href="dom_nodes_nodelist.asp">node list object</a> is returned.</p>
<p><a href="dom_mozilla_vs_ie.asp">Different browsers</a> treat new line, or
space characters, between nodes differently.</p>
<p>To <a href="dom_mozilla_vs_ie.asp">ignore empty text nodes</a> between
element nodes, you can check the node type.</p>
<p>Nodes can be <a href="dom_nodes_navigate.asp">navigated</a> using node
relationships.</p>
<p>Our <a href="dom_examples.asp">XML DOM examples</a> also represent a summary of this XML
DOM tutorial.</p>

<h2>What to Study Next?</h2>
<p>Our recommendation is to learn about XSLT.</p>
<p>If you want to learn more about validating XML, we recommend DTD and XML
Schema.</p>
<p>Below is a short description of each subject.</p>
<hr />
<h2><b>XSLT (XML Stylesheet Language Transformations)</b></h2>
<p>XSLT is the style sheet language for XML files.</p>
<p>With XSLT you can transform XML documents into other formats, like XHTML.</p>
<p>If you want to learn more about XSLT, please
visit our <a href="../xsl/default.asp">XSLT tutorial</a>.</p>
<hr />
<h2><b>XML DTD (Document Type Definition)</b></h2>
<p>The purpose of a DTD is to define what elements, attributes and entities is
legal in an XML document.</p>
<p>With DTD, each of your XML files can carry a description of its own format
with it.</p>
<p>DTD can be used to verify that the data you receive, and your own data, is
valid.</p>
<p>If you want to learn more about DTD, please
visit our <a href="../dtd/default.asp">DTD tutorial</a>.</p>
