使用php/javascript查找并替换网页中的所有链接

Question

我需要在一些HTML代码的一部分中找到链接,并用两个不同的绝对或基本域替换所有链接,然后是页面上的链接...

我找到了很多想法并尝试了很多不同的解决方案.在这一方面运气不好......请帮助我!谢谢!!

这是我的代码:

<?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">');
$end = strpos($content,'</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}";
    }

}
?>

当我运行此代码时,我得到htmlParseEntityRef:expecting';' 警告我加载html的行

var links = document.getElementsByTagName("a");会得到你所有的链接.这将循环通过它们:

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