Parse multi data sources

We have already seen two single sources where CSS data could come from. The last one allow to parse data from multiple sources at once. HTML_CSS::parseData() function take an array as first argument. Each item is either a filename (with .css extension) or a string. Each source is merge to produce at end a unique style sheet.

In script below we load selector definitions from two independent sources: a string and a css file which contents duplicate definitions (parseFile() 2nd argument to set to true to catch this situation; see next section for explains). Internet Explorer).

  1. <?php
  2. require_once 'HTML/CSS.php';
  3.  
  4. $css = new HTML_CSS();
  5.  
  6. // 1. a string to parse
  7. $strcss = '
  8. body, p { background-color: white; font: 1.2em Arial; }
  9. p, div#black { color: black; }
  10. div{ color: green; }
  11. p { margin-left: 3em; }
  12. ';
  13. $css->parseString($strcss);
  14.  
  15. // 2. a css file with duplicate definitions
  16. $css->parseFile('iehack.css', true);
  17.  
  18. $css->display();
  19. ?>
