AJAX XML File

This lesson is part of XML · All levels

Summary

AJAX can load static XML files from a server, such as a catalog or news list, and then display them to a page. Once a GET request is sent, the response is read with responseXML so that the data immediately forms a DOM tree. The resulting elements are then taken with getElementsByTagName for further processing.

Key points

XML files are loaded via GET request to the server URL
ResponseXML returns XML documents in the form of a DOM tree
Elements taken with getElementsByTagName
JavaScript loops are used to compile a list of results to a page
CORS restrictions may prevent loading local XML files
