Parse XML using PHP, Here we have 2 files one is the XML and other is the PHP. Very easy script to parse an xml file. Here i am using a big xml file and extracting data from that using php.
The first file is the XML file, name the file as parse.xml
<?xml version="1.0" encoding="UTF-8"?> <rss version="2.0"> <channel> <title>Tutorialz Images</title> <link>http://www.tutorialz.tk</link> <language>en-us</language> <image> <url>102724_31082007.jpg</url> <title></title> <link>http://www.tutorialz.tk</link> <description/> </image> <image> <url>369877_31082007.jpg</url> <title></title> <link>http://www.tutorialz.tk/22562/userid/3</link> <description/> </image> <image> <url>898438_0312080814461mira5abcjpg.jpg</url> <title> </title> <link>http://www.tutorialz.tk/22560/userid/3</link> <description/> </image> <image> <url>211000_withkids.jpg</url> <title>rahul and gokul </title> <link>http://www.tutorialz.tk/22469/userid/3</link> <description/> </image> <image> <url>180625_cycle.jpg</url> <title> </title> <link>http://www.tutorialz.tk/22467/userid/3</link> <description/> </image> <image> <url>368384_mission.jpg</url> <title>The mission begins </title> <link>http://www.tutorialz.tk/22465/userid/3</link> <description/> </image> <image> <url>370625_04082007.jpg</url> <title> </title> <link>http://www.tutorialz.tk/22350/userid/3</link> <description/> </image> <image> <url>292629_06082007744.jpg</url> <title> </title> <link>http://www.tutorialz.tk/22330/userid/3</link> <description/> </image> <image> <url>22314</url> <title></title> <link>http://www.tutorialz.tk/22314/userid/3</link> <description/> </image> <image> <url>22313</url> <title>comfort inn attham</title> <link>http://www.tutorialz.tk/22313/userid/3</link> <description/> </image> <image> <url>22295</url> <title>dial 100 if you see any of these person</title> <link>http://www.tutorialz.tk/22295/userid/3</link> <description/> </image> <image> <url>811298_30072007676.jpg</url> <title> </title> <link>http://www.tutorialz.tk/22200/userid/3</link> <description/> </image> <image> <url>974623_dog.jpg</url> <title> </title> <link>http://www.tutorialz.tk/22179/userid/3</link> <description/> </image> <image> <url>270873_15082007.jpg</url> <title></title> <link>http://www.tutorialz.tk/22103/userid/3</link> <description/> </image> <image> <url>22102</url> <title></title> <link>http://www.tutorialz.tk/22102/userid/3</link> <description/> </image> <image> <url>22101</url> <title>kenney</title> <link>http://www.tutorialz.tk/22101/userid/3</link> <description/> </image> <image> <url>22100</url> <title></title> <link>http://www.tutorialz.tk/22100/userid/3</link> <description/> </image> <image> <url>22099</url> <title></title> <link>http://www.tutorialz.tk/22099/userid/3</link> <description/> </image> <image> <url>22098</url> <title></title> <link>http://www.tutorialz.tk/22098/userid/3</link> <description/> </image> <image> <url>22097</url> <title></title> <link>http://www.tutorialz.tk/22097/userid/3</link> <description/> </image> </channel> </rss>
