There is an XML file with the following content:

The Code is as follows:

<? Xml version = "1.0"?>


Simpsons

Law & Order
NBC

Here we use XMLReader extension to parse and process the file. XMLReader also has the advantage of reading data in the form of Stream, that is, even if the xml file is large, it can still be processed with ease. The following describes how to process the above files:

The Code is as follows:

$ IndexUrl = 'HTTP: // www.xxx.com/xxx.xml ';
$ Reader = new XMLReader ();
$ Reader-> open ($ indexUrl );
$ CountElements = 0;

While ($ reader-> read ()){
If ($ reader-> nodeType = XMLReader: ELEMENT ){
$ NodeName = $ reader-> name;
}
If ($ reader-> nodeType = XMLReader: TEXT &&! Empty ($ nodeName )){
Switch ($ nodeName ){
Case 'name ':
$ Name = $ reader-> value;
Break;
Case 'channel ':
$ Channel = $ reader-> value;
Break;
Case 'start ':
$ Start = $ reader-> value;
Break;
Case 'duration ':
$ Duration = $ reader-> value;
Break;
}
}
}
$ Reader-> close ();
