Php uses java to parse xml_PHP tutorial
Please first install the JAVA execution environment and combine it with PHP. For details, please refer to http://www.phpx.com/happy/thr78795.html
or download http://www.javax.org/download/php_java.rar
I wrote a readme.txt description document inside, and this compressed package is a simple example.
To download my JAVA source code, please go to http://www.javax.org/download/JavaXml.rar
If you have other questions, please go to http://www.javax.org/ to ask.
At first I wanted to use PHP to parse XML, but found that it was a bit troublesome for PHP to parse XML. It seemed that PHP5 was more convenient, but I did not install 5 here, so it was still 4.3. Later, I saw an IBM article (http://www-900.cn.ibm.com/developer...kit/index.shtml) that mentioned that JAVA can be used, so I will try it now.
The XML file to be parsed: first.xml, the content is as follows:
Where
Look at the file when parsed by PHP:
$JavaXml = new Java("JavaXml"); //Here is a class that generates a JAVA class I wrote to parse XML data
$JavaXml->init(); //Here is initialization, such as taking the XML file directory in the global.properties file (of course you need to change it to your XML file directory after downloading the example)
$JavaXml-> Parse("first.xml"); //Specify the file to be parsed, relative to the directory specified in the global.properties file
$JavaXml->get(0); //Here is to get the first node
echo $JavaXml->getValue("name")."
"; //Get the name tag value of the first node
echo $JavaXml->getValue("age")."
"; //Get the age tag value of the first node
$JavaXml->setValue("name","Big Head Dad"); //Set the name tag value of the first node to Big Head Dad
$JavaXml->get(1); //Get the second node here
echo $JavaXml->getValue("name")."
"; //Get the second node Node name tag value
echo $JavaXml->getValue("age")."
"; //Get the second node age tag value
?>
$ JavaXml->get(0); gets the node position. For example, my XML file has two groups of
The final output is

Because $JavaXml->setValue("name","Big Head Dad" ); This sentence modifies the value of the name tag of the first node. The XML file has been updated, so when the PHP file is executed again, the result will become
Big Head Daddy

The above simple sentences have completed the analysis. Below is my JAVA class, which uses JDOM to parse XML.
import org.jdom.* ;
import org.jdom.output.* ;
import org.jdom.input.* ;
import java.io.* ;
import java.util.*;
public class JavaXml {
public String path=null;
public String XmlFileName=null;
public SAXBuilder sax=null;
public Document doc=null;
public Element root=null;
public List xlist=null;
public Element e=null;
public Element value=null;
public String getTest(){
return new String("haha");
}
public JavaXml(){
}
public String init(){
InputStream is = getClass().getResourceAsStream("global.properties");
Properties dbProps = new Properties();
try {
dbProps.load( is ) ;
}
catch ( Exception e ) {
return ("error file");
}
this.path=dbProps.getProperty("XmlPath");
return ("ok");
}
public void get(int child){
this.e=(Element)xlist.get(child);
}
public String getValue(String name){
this.value=e.getChild(name);
return this.value.getText();
}
public void setValue(String name,String value)throws Exception{
this.value=e.getChild(name);
this.value.setText(value);
XMLOutputter xmlout=new XMLOutputter();
xmlout.output(doc,new FileOutputStream(path+XmlFileName));
}
public void Parse(String XmlFileName)
throws Exception
{
this.XmlFileName=XmlFileName;
this.sax=new SAXBuilder();
this.doc=sax.build(new FileInputStream(path+XmlFileName));
this.root=doc.getRootElement();
this.xlist=root.getChildren();
}
}

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
