Find and replace all links in a web page using php/javascript

I need to find links in a part of some html code and replace all the links with two different absolute or base domains followed by the link on the page...

I have found a lot of ideas and tried a lot different solutions.. Luck aint on my side on this one.. Please help me out!! Thank you!!

This is my code:

<?php
$url = "http://www.oxfordreference.com/views/SEARCH_RESULTS.html?&q=android";
$raw = file_get_contents($url);
$newlines = array("\t","\n","\r","\x20\x20","\0","\x0B");
$content = str_replace($newlines, "", html_entity_decode($raw));

$start = strpos($content,'<table class="short_results_summary_table">');
$end = strpos($c开发者_如何学JAVAontent,'</table>',$start) + 8;
$table = substr($content,$start,$end-$start);

echo "{$table}";

$dom = new DOMDocument();
$dom->loadHTML($table);

$dom->strictErrorChecking = FALSE;

// Get all the links
$links = $dom->getElementsByTagName("a");
foreach($links as $link) {
  $href = $link->getAttribute("href");
  echo "{$href}";

  if (strpos("http://oxfordreference.com", $href) == -1) {
  if (strpos("/views/", $href) == -1) {
     $ref = "http://oxfordreference.com/views/"+$href;
  }
  else 
      $ref = "http://oxfordreference.com"+$href;
    $link->setAttribute("href", $ref);
    echo "{$link->getAttribute("href")}";
  }
}
$table12 = $dom->saveHTML;

preg_match_all("|<tr(.*)</tr>|U",$table12,$rows);

echo "{$rows[0]}";

foreach ($rows[0] as $row){

    if ((strpos($row,'<th')===false)){

        preg_match_all("|<td(.*)</td>|U",$row,$cells);       
        echo "{$cells}";
    }

}
?>

When i run this code i get htmlParseEntityRef: expecting ';' warning for the line where i load the html

var links = document.getElementsByTagName("a"); will get you all the links. And this will loop through them:

 for(var i = 0; i < links.length; i++)
    {
        links[i].href = "newURLHERE";
    }

You should use jQuery - it is excellent for link replacement. Rather than explaining it here. Please look at this answer.

I recommend scrappedcola's answer, but if you dont want to do it on client side you can use regex to replace:

ob_start();
//your HTML

//end of the page
$body=ob_get_clean();
preg_replace("/<a[^>]*href=(\"[^\"]*\")/", "NewURL", $body);
echo $body;

You can use referencing (\$1) or callback version to modify output as you like.
