用于DOM中的DOM解析器的SAX解析器脚本

I need the SAX parser code for my DOM Document code.

If anybody would be kind enough to provide me the code for the same.

 function flipkart_price_fetch($sel_image){  
    global $sel_image;  
    $price = file_get_contents("{$sel_image['flipkart_content']}");  
    $dom = new DOMDocument();  
    @$dom->loadHTML($price);  
    $divs = $dom->getElementsByTagName('span');  
    foreach($divs as $div){  
        if($div->getAttribute('class') == 'fk-font-verybig pprice fk-bold'){  
            echo $div->nodeValue;  
            }  
        }  
    } 

I don't think DOM is the performance hog here, but the iteration of all span element nodes. DOMXpath allows to use Xpath expressions to fetch nodes directly:

$dom = new DOMDocument();  
@$dom->loadHTMLFile($sel_image['flipkart_content']);  
$xpath = new DOMXpath($dom);

// this matches the node by the class name "pprice"
$price = $xpath->evaluate(
  'string(.//span[contains(concat(" ", normalize-space(@class), " "), " pprice ")])'
);

echo $price;

Search SO and/or the Web for Xpath.

You have some additional errors in your source:

1. global $sel_image;

   $sel_image is the function argument, here no reason to make it a global state.

2. "{$sel_image['flipkart_content']}"

   This string contains only the variable, use the variable directly $sel_image['flipkart_content'] or cast it to a string (string)$sel_image['flipkart_content']

3. $price = file_get_contents("{$sel_image['flipkart_content']}");

   Here is no need to load the file/url separately - use DOMDocument::loadHTMLFile()
