How to access XML data using javascript _ javascript

Internet Explorer (IE) is now a standard software for instances that use javascript to access XML data. We can see that almost every machine running different versions of Windows (and many other operating systems) uses IE. Microsoft has used ActiveX controls to include IE functions in sophisticated XML processing technology.

In this article, we will describe how to use ActiveX functions in IE to access and parse XML documents, thus allowing Web surfers to manipulate them.

Surfing the internet
We start with A standard document, as shown in table. This document contains simple ordered data for browsing by web surfers. In addition to displaying the data, we also provide a simple user interface that allows web surfing to browse XML documents.

Table A: order. xml

We use a web form to access this XML document. This form displays the SKU, price, quantity, subtotal of each part, and descriptions of each option in the sequence. Our form also contains buttons for the forward and backward browsing options.

Web page Composition
An important part of a webpage is the form. We will use a table to display it on the screen in a readable manner. The following code snippet shows the HTML table:



Note that the table contains two buttons: getDataNext () and getDataPrev () to view the previous and next records, this is what we will discuss.

Script
In fact, the essence of our webpage is not the form, but the form control script. There are four parts in our script. First, we initialize the webpage by loading the XML document. The second part is to navigate to the next record. Step 3: navigate to the previous record. The fourth part is to extract a single value from the XML document. Table B shows all the content of our webpage.

Table B: jsxml.html
