All major browsers have a built-in XML parser to read and manipulate XML.
The XML DOM contains methods to traverse XML trees, access, insert, and delete nodes.
However, before an XML document can be accessed and manipulated, it must be loaded into an XML DOM object.
Most browsers have a built-in XML parser.
The following code loads and parses an XML string:
Note: Internet Explorer uses the loadXML() method to parse an XML string, while other browsers use the DOMParser object.
For security reasons, modern browsers do not allow access across domains.
This means, that both the web page and the XML file it tries to load, must be located on the same server.
The examples on W3Schools all open XML files located on the W3Schools domain.
If you want to use the example above on one of your web pages, the XML files you load must be located on your own server.
