PHP XML File Interpretation class application example, Phpxml class application Example

The examples in this paper describe the PHP XML file interpretation class and its usage, which is a very practical technique. Share to everyone for your reference. Specific as follows:

The XMLParser.class.php class file is as follows:

<?php/** XML File Parsing class * date:2013-02-01 * author:fdipzone * ver:1.0 * * Func: * Loadxmlfile ($xmlfile) read into XML file   Output array * loadxmlstring ($xmlstring) read into xmlstring output array */class xmlparser{/** read XML file * @param String $xmlfile * @return Array */Public Function Loadxmlfile ($xmlfile) {//get xmlfile content $xmlstring = file_exists ($xml File)?     File_get_contents ($xmlfile): ";     Parser XML List ($flag, $data) = $this->parser ($xmlstring);   return $this->response ($flag, $data);     }/** reads xmlstring * @param String $xmlstring * @return Array */Public Function loadxmlstring ($xmlstring) {     Parser XML List ($flag, $data) = $this->parser ($xmlstring);   return $this->response ($flag, $data); }/** interprets XML content * @param String $xmlstring * @return Array */Private Function parser ($xmlstring) {$flag = f     Alse;     $data = Array (); Check XML format if ($this->checkxmlformat ($xmlstring)) {$flag = trUe       XML to Object $data = simplexml_load_string ($xmlstring, ' simplexmlelement ', libxml_nocdata);     object to array $this->objecttoarray ($data);   } return Array ($flag, $data);     }/** Check that the XML format is correct * @param String $xmlstring * @return Boolean */Private Function Checkxmlformat ($xmlstring) {     if ($xmlstring = = ") {return false;      } $xml _parser_obj = Xml_parser_create ();     if (Xml_parse_into_struct ($xml _parser_obj, $xmlstring, $vals, $indexs) ===1) {//1:success 0:fail return true;     }else{return false; }}/** object to array * @param object $object * @return Array */Private Function Objecttoarray (& $object          {$object = (array) $object;       foreach ($object as $key = + $value) {if ($value = =) {$object [$key] = "";           }else{if (is_object ($value) | | Is_array ($value)) {$this->objecttoarray ($value);         $object [$key] = $value;       }}}}/** output returns * @param boolean $flag true:false * @param array $data converted data * @return Array */privat   e function response ($flag =false, $data =array ()) {return Array ($flag, $data); }}?>

The Demo sample program is as follows:

<?php require "XMLParser.class.php";  $xmlfile = ' file.xml '; $xmlstring = ' <?xml version= ' 1.0 "encoding=" Utf-8 "?> 
 
   
  
   
  
    
  
    
  
   
   
    
     
    fdipzone
   
     
   
    
     
    1 28
   
     
   
    
   
     
  
    
 
  '; Echo '
'; $xml _parser = new Xmlparser (); echo "Response xmlfile\r\n"; List ($flag, $xmldata) = $xml _parser->loadxmlfile ($xmlfile); if ($flag) {   print_r ($xmldata);} echo "Response xmlstring\r\n"; list ($flag, $xmldata) = $xml _parser-> Loadxmlstring ($xmlstring); if ($flag) {   print_r ($xmldata);} Echo '

The XML pre-defined constants for PHP can be consulted in the official documentation:

How PHP generates XML files

#使用dom生成xml, note that there are no spaces in the generated XML.
$dom =new DOMDocument (' 1.0 ', ' utf-8 ');
$path = "Test.xml"; $path the storage path for the XML file.

$module = $dom->createelement (' newmodule ');//root node
$dom->appendchild ($module);

$year = $dom->createelement (' year '); Add Attribute Node
$name = $dom->createattribute (' name ');
$name->nodevalue= "Latest News";
$year->setattributenode ($name);
$module->appendchild ($year);

$news = $dom->createelement (' News ');
$year->appendchild ($news);

$date = $dom->createelement (' Date ');
$date _value= $dom->createtextnode (' 01-24 ');
$date->appendchild ($date _value);
$news->appendchild ($date);

$title = $dom->createelement (' title ');
$title _value= $dom->createtextnode ('<![CDATA[最新动态]]>');
$title->appendchild ($title _value);
$news->appendchild ($title);

$info = $dom->createelement (' info ');
$info _value= $dom->createtextnode ('<![CDATA[ 表面采用进口楸木木皮拼贴成精美的拼花，自然清晰的木材纹理得到完美的呈现，各种材质的合理搭配缔造了雅意系列精致的家具产品。 <br /> ]] >');
$info->appendchild ($info _value);
$news->appendchild ($info);

echo $dom->savexml ();
$dom->save ($path);
?>

Reading XML content from a PHP file

<%
Dim Xml,objnode,objatr,ncntchd,ncntatr
Set xml=server.createobject ("Microsoft.XMLDOM")
Xml. Async=false
Xml. Load (Server.MapPath ("Test.xml"))

Set objnode=xml.documentelement
Ncntchd=objnode.childnodes.length-1

' This defines the value that ASP reads the XML file by passing this value to determine what data is being read

For I=0 to Ncntchd
Set Objatr=objnode.childnodes.item (i)
Ncntatr=objatr.attributes.length-1

' All the records in a record, the record is starting from 0

For J=0 to Ncntatr
Response.Write ObjAtr.Attributes.item (j). text& "
"
Next
Response.Write "
"
Next

Set objatr=nothing
Set objnode=nothing
Set xml=nothing
