css parser

Is there anything available to parse existing style sheets and convert to the XML format? Would like to populate the style drop down with styles from an existing style sheet.

I was looking for a css parser and only found one called cypress in java. Server side PHP would be sweet

RE: css parser

Hi Dustin,

i wrote a little css parser myself. I hope it will come in handy for you also. Below is the source:

Grtz,

<?php 
 
// this file will convert a css file to the fckstyles xml layout 
// the only requirement is that the style in the stylesheet start with 
// a dot(.), the element name it is intented for and a underscore, eg: .img_image_on_left{} 
// as a parameter, a valid stylesheet is taken (/usr/home/somehost/stylesheet.css) or  
// (http://www.somehost.com/styles.css) 
// 
// in this file, the name of the style is modified, the ".elementname_" is stripped and after 
// that, underscores are replaced for readability; 
// 
// there's an array of allowed tags, only elements wth that tagname will be displayed in the 
// xml file (and thus style combo) 
 
 
function echo_styles($strStylesheet){ 
 
// define an array of valid tags 
$arrTags = array("span","img", "table", "tr", "td", "input", "select", "textarea", "hr", "object"); 
 
// open the stylesheet for reading 
if($fp = fopen($strStylesheet, "r")){  
 
$contents = ''; 
while(!feof($fp)) { 
$contents .= fread($fp, 8192); 
} 
 
// read the content in an array 
//$stylesheet_content = split("\n", $contents); 
$stylesheet_content = split("}",$contents); 
$theXML = ''; 
 
for($i=0;$i<count($stylesheet_content);$i++){ 
 
$style = $stylesheet_content[$i]; 
$style_name = trim(substr($style,0,strpos($style,"{"))); 
if(substr($style_name,0,1) == "."){ 
 
$style_name = substr($style_name,1); 
 
// for each element, display an xml tag 
$theElement = substr($style_name, 0, strpos($style_name,"_")); 
 
if(in_array(strtolower($theElement), $arrTags)){ 
$new_style_name = str_replace("_", " ", substr($style_name, strpos($style_name,"_")+1, strlen($style_name)-strpos($style_name,"_"))); 
$theXML .= "<Style name=\"$new_style_name\" element=\"$theElement\">\n"; 
$theXML .= " <Attribute name=\"class\" value=\"$style_name\" />\n"; 
$theXML .= "</Style>\n"; 
} 
 
} else { 
 
if(trim(substr($style,0,7)) == "@import"){ 
 
$theStyleSheets = split("@", $style); 
 
for($i=0;$i<count($theStyleSheets);$i++){ 
 
$theStyleSheet = substr($theStyleSheets[$i], 7, strlen($theStyleSheets[$i])); 
$theStyleSheet = str_replace("'","", $theStyleSheet); 
$theStyleSheet = str_replace(";","", $theStyleSheet);  
$number_dirs_back = count(split("../", $theStyleSheet)); 
$theStyleSheet = str_replace("../","", $theStyleSheet); 
 
for($k=0;$k<$number_dirs_back;$k++){ 
 
$thePath = substr($site_path,0,strrpos($site_path, "/")); 
$thePath = trim(substr($thePath,0,strrpos($thePath, "/"))); 
 
} 
 
echo_styles(trim($thePath."/".$theStyleSheet)); 
 
}  
 
} 
} 
} 
} 
 
return $theXML; 
 
} 
// send the XML header to the broser, so it knows it's XML 
header("Content-type: text/xml"); 
header("Pragma: public"); 
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
 
// echo the XML tag first and the root node 
echo "<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n";

echo " <Styles>";

// now send the styles
echo echo_styles($_GET['css']);

// and close the style tag again
echo " </Styles>";

?>
