This article describes the method of PHP parsing RSS. Share to everyone for your reference. Specifically as follows:
1. PHP code is as follows:
Copy Code code as follows:
Require "xml/rss.php";
$rss = new Xml_rss ("Http://php.net/news.rss");
$rss->parse ();
foreach ($rss->getitems () as $item) {
Print_r ($item);
}
?>
2. The rss.php code is as follows:
Copy Code code as follows:
$database = "Nameofthedatabase"

Congratulations on your winning, there are some characters that use any kind of encoding no different or wrong coding does not lead to a bit supplement, then I can do nothing.

For a JSON-formatted string, you need to be aware of the parentheses when you use eval to convert a string to a JSON object. As shown below:
The results of this code are as follows:
The results of this code are as follows:
Figure 1: Code Run results
The results appear as above because the eval itself can parse and run the code in the string. Since JSON starts and ends in {}, it is treated as a block of statements in JS, so it i
also be used to space, otherwise JSON will not be able to parse, go to the space method:
public string Replaceblank (String str) {
string dest = "";
if (str!= null) {pattern
p = pattern.compile ("\\s*|\t|\r|\n");
Matcher m = p.matcher (str);
Dest = M.replaceall ("");
Pattern P2 = pattern.compile ("\\s*\");
Matcher m2 = p2.matcher (dest);
Dest = M2.replaceall ("\");
Dest = Dest.replace ("=\" "," = ' ");
p = pattern.co

Note: If the above generation XML is changed to $dom->save (' books.xml '), a books.xml file is generated directly
Here we use SimpleXML to parse XML files
The SimpleXML function allows you to convert XML to an object.
You can work with this object, just as you would any other object, with a normal property selector or an array iterator.
Some of these functions require the latest version of PHP.Install
Although there are already two standard parsing methods for DOM and sax in Java
But it is not easy to operate, for a beginner like me, part of the code is living nausea
To this end, the great third party development team developed jdom and DOM4J tools
Given the current trend, we are here to talk about the basic usage of dom4j, not involving complex operations such as recursion.
DOM4J is a lot of use, the official online example is a little obscure, here is not written
First we need to creat
JSON (JavaScript Object notation) is a simple data format that is lighter than XML. JSON is the native format of JavaScript, which means that processing JSON data in JavaScript does not require any special APIs or toolkits.
The rule of JSON is simple: an object is an unordered set of ' name/value pairs '. An object begins with "{" (opening parenthesis), and "}" (closing parenthesis) ends. Each "name" followed by a ":" (colon); "' Name/value ' pairs" (comma) separated
