This article mainly introduces the application of the name to access the XML document example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

One demand

Use the http://www.php.cn/code/8145.html" target= "_ blank" > getElementsByTagName method to access the data in the XML document by name.

Second analysis

Access XML documents by application name

First create an instance of the Microsoft parser using ActiveXObject, and then load the XML document into memory.

Then the getElementsByTagName () method is used to get the references to the number element, the name element, and the object element, and the result is an array, with each element in the array corresponding to an element in the XML document in the same order.

Finally, the value of the text contained in the corresponding element is obtained, and the string is spliced.

Three attentions

Count from 0 in the subscript of the array of JavaScript. The FirstChild attribute indicates that you want to access the text contained in the name element, not the name element itself; the data attribute gets the value of the node.

Four codes
