Question

我想找到一个preg_match结果并检索信息。在那场比赛之后，我需要找到在它之后有多少hmtl标签'a'，直到下一场比赛。我把那些html'A'标签的数量和preg_match放在一个数组中。所有这些都在一个文件中，我可以修改文件。

这样做的目的是识别每个html'a'标签并给他一个类别（matche）。唯一的问题是我验证文件的每一行，我想查看一个简单的字符串。这是我的代码和文件。

功能

function retrieveCatAndNumber($filepath){

$nbTag = array();
$lines = file($filepath);

//print_r($lines);
$i = 0;
$countA = 0;
$lineNumber = 1;
$nbLines = count($lines);

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {

 // echo htmlspecialchars($line)."<br>";
  if(preg_match("/<a(.*?)<\/a>/s", $line, $matcheA)){
    $countA++;
  }//if A
 // echo "/<td class=pp bgcolor='#0051AB'>(.*?)<\/td>";
 $result = preg_match_all("/<td class=pp bgcolor='#0051AB'>(.*?)<\/td>/s", trim($line), $matcheTD);

  if($result == 1){
    //echo $result;
    $prev = $i - 1;
     //echo htmlspecialchars($line)."<BR>";
     $nbTag[$i][0] = preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $matcheTD[0]);                                   

             print_r($matcheTD);
    echo "<br>";
     if($i != 0){
       $nbTag[$prev][1] = $countA;
       $countA = 0;
     }

     $i++;
  }//if TD

  if($lineNumber == $nbLines){
    $nbTag[$i - 1][1] = $countA;
    $countA = 0;
  }
  $lineNumber++;
}//Foreach line of file

echo "\t\t The category and number of links : ok<BR>";

return $nbTag;

} // retrieveNbTag

不要尝试用正则表达式解析html文件！使用库来解析html。

您可以使用http://www.php.net/manual/en/domdocument.loadhtml.php或其他一些图书馆......
