PhpsimplexmlElement: namespace implementation code for operating xml

Source: Internet
Author: User
This is what happened at noon today. someone asks for help in the group. for example, if the tag in xml is & lt; xx: xxxx & gt; content & lt; xx: xxxx & gt; in this case, the value of xx: xxxx is not obtained. After reading this question, the first reaction was the relationship between namespace, but I never used simplexml to operate namespace. so I opened the manual and checked the information. The problem was not solved, google eventually solved the problem.

A friend who asked the question posted the data source, from:

The code is as follows:

This structure is shown in the preceding address. this is the XML data that I have formatted. 456 .

The final code is as follows:

The code is as follows:


$ X = new SimpleXmlElement ($ str );
Foreach ($ x-> entry as $ t ){
Echo $ t-> id ."
";
Echo $ t-> updated ."
";
$ Namespaces = $ t-> getNameSpaces (true );
$ Gd = $ t-> children ($ namespaces ['gd ']);
Echo $ gd-> phoneNumber;
}


Of course, if it is not written as above, it can also be written as follows:

The code is as follows:


$ X = new SimpleXmlElement ($ str );
Foreach ($ x-> entry as $ t ){
Echo $ t-> id ."
";
Echo $ t-> updated ."
";
// $ Namespaces = $ t-> getNameSpaces (true );
// Note the difference between this and the above section
$ Gd = $ t-> children ('http: // schemas.google.com/g/2005 ');
Echo $ gd-> phoneNumber;
}


Just like the second method, it is hard-coded. this is not good. in case of any change, you have to change N more codes.
The problem arises one after another, such as the following section:

The code is as follows:

This non-standard XML does not define a namespace. what should I do? In this case, SimpleXmlElement can be solved directly, but it will report warnging because he thinks the namespace event does not exist.
Solution:

The code is as follows:


$ Xml = @ new SimpleXmlElement ($ str); // add @ to the front to stop the error.
Echo"

";
Print_r ($ xml );

Currently, this solution is better.
