PHP to read RRs

Previously, because of the need to do the school forum, has written a read Shou forum RRs of a section of PHP, write out for everyone to reference

Here is the definition function to extract the data:

The property that handles the start tag refers to the

$attrs is a multidimensional array, the key value is the property name, and the value is the value of the property

function startelement ($parser, $element _name, $attrs) {

Global $temp, $current _tag;

$current _tag = $element _name;

Switch ($element _name) {

Case ' ITEM ':

Echo ';

break;

Default:

break;

}



}



$current _tag tells us the tag we're working on, we'll use it later in the Characterdata function.



function EndElement ($parser, $element _name, $attrs) {

Global $temp, $current _tag;

Switch ($element _name) {

Case ' ITEM ':

Return_page ($temp);

$temp = ";

break;

Default:

break;

}

}



The data that is passed to this function is between the elements

For example, for<title>Title here</title>, $data is equal to ' Title here '

function Characterdata ($parser, $data) {

Global $current _tag, $temp, $catID;

Switch ($current _tag) {

Case ' TITLE ':

$temp [' title '] = $data;

$current _tag = ";

break;

Case ' LINK ':

$temp [' url '] = $data;

$current _tag = ";

break;

Case ' AUTHOR ':

$temp [' author '] = $data;

$current _tag = ";

Case ' DESCRIPTION ':

$temp [' description '] = $data;

$current _tag = ";

Default:

break;

}

}

?>








function Return_page () {

Global $temp;

Echo ' O '. $temp [' title ']. '
' ;


}



The content of the analysis, known as RRS, can be a network location, or it can be a file

$xml _file = ' http://club.sohu.com/list-70th-0-0.xml ';



Define character Set, default is UTF-8

$type = ' UTF-8 ';



Set up a parser

$xml _parser = Xml_parser_create ();



Set resolution options

Xml_parser_set_option ($xml _parser, xml_option_case_folding, true);

Xml_parser_set_option ($xml _parser, xml_option_target_encoding, ' UTF-8 ');



Tell PHP what function to invoke when discovering elements

These functions also handle the attributes of the element

Xml_set_element_handler ($xml _parser, ' startelement ', ' endElement ');



Tell PHP what function to call the character data

Xml_set_character_data_handler ($xml _parser, ' characterdata ');



if (! ($fp = fopen ($xml _file, ' R '))) {

Die ("Due to network problems, temporarily unable to obtain data, please wait to refresh and try again");

}



To parse the entire file through a loop


while ($data = Fread ($fp, 1024))

{

Xml_parse ($xml _parser, $data, feof ($fp));

}

Fclose ($FP);

Xml_parser_free ($xml _parser);



?>

Alternatively, you can add a script for the JavaScript that is used to pre-load the Web page

< SCRIPT LANGUAGE = "JavaScript" >





< SCRIPT LANGUAGE = "JavaScript" >



< style type = "Text/css" >





< div id = "LD" style = "position:absolute; left:0px; top:0px; width:100%; height:100%; Background-color: #ffffFF; z-index:1000; ">

< br >

< br >< br >< br >< br >< br >< br >< br >< br >< br >< BR &GT;&L T br >

< table align = "center" width = "50%" >

< tr >

< td align = "center" >< Font color = #0000ff >< B > Sohu Forum < br >

< br >

< font color = "#0000ff" > Loading Please wait a moment ...





< table width = "50%" align = "center" border = "0" cellspacing = "1" cellpadding = "0"
