[removed] REGEX to change all relative Urls to Absolute

Question

I\'m currently creating a Node.js webscraper/proxy, but I\'m having trouble parsing relative Urls found in the scripting part of the source, I figured REGEX would do the tri

Answer 1

From a comment by Rob W above about the base tag I wrote an injection function:

function injectBase(html, base) {
  // Remove any  elements inside      
  html = html.replace(/(<[^>/]*head[^>]*>)[\s\S]*?(<[^>/]*base[^>]*>)[\s\S]*?(<[^>]*head[^>]*>)/img, "$1 $3");

  // Add  just before   
  html = html.replace(/(<[^>/]*head[^>]*>[\s\S]*?)(<[^>]*head[^>]*>)/img, "$1 " + base + " $2");  
  return(html);
}
