<? Php
$ Open_tags = array (
'Story' => '<STORY> ',
'Title' => '<TITLE> ',
'URL' => '<URL> ',
'Author' => '<AUTHOR>'
);
$ Close_tags = array (
'Story' => '</STORY> ',
'Title' => '</TITLE> ',
'URL' => '</URL> ',
'Author' => '</AUTHOR>'
);
?>

<? Php
// The following is the definition function to extract data:

// Processing start tag attributes refer
// $ Attrs is a multi-dimensional array. The key value is the attribute name and the value is the value of this attribute.
Function startElement ($ parser, $ name, $ attrs = ''){
Global $ open_tags, $ temp, $ current_tag;
$ Current_tag = $ name;
If ($ format = $ open_tags [$ name]) {
Switch ($ name ){
Case 'store ':
Echo 'new story :';
Break;
Default:
Break;
}
}
}

// $ Current_tag indicates the tag being processed, which will be used in the characterData function.
//
// When we encounter the </STORY> Mark, we know that we need to flush all the temporary variables to prepare for the next mark.
<Lt;/STORY> ',
'Title' => '</TITLE> ',
'URL' => '</URL> ',
'Author' => '</AUTHOR>'
);
?>
