搜索html中的内容(Search the contents in the html)

 HTML中有两个不同的标签，分别是row0-1和row1-1 。 我想从row1-1标记中搜索名为row1Time的HTML中的内容。 
 
 这是HTML示例： 
 
<li class="zc-ssl-pg" id="row0-1" style="">
    <span id="row1Time" class="zc-ssl-pg-time">4:00 PM</span>
    <li class="zc-ssl-pg" id="row1-1" style="">
    <span id="row1Time" class="zc-ssl-pg-time">3:00 PM</span>
 
 这是我的PHP： 
 
    <?php
    $errmsg_arr = array();
    $errflag = false;
    $link;

    function db_connect()
    {
      define('DB_HOST', 'localhost');
      define('DB_USER', 'myusername');
      define('DB_PASSWORD', 'mypassword');
      define('DB_DATABASE', 'mydbname');

      $errmsg_arr = array();
      $errflag = false;
      $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);

      if(!$link) 
      {
        die('Failed to connect to server: ' . mysql_error());
      }

      $db = mysql_select_db(DB_DATABASE);
      if(!$db) 
      {
        die("Unable to select database");
      }
    }

    $links = $row['links'];
    include ('simple_html_dom.php');
    $html = file_get_html($links);
    //echo $row['links'];

    $base = $row['links'];

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_URL, $base);
    curl_setopt($curl, CURLOPT_REFERER, $base);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    $str = curl_exec($curl);
    curl_close($curl);

    // Create a DOM object
    $html = new simple_html_dom();
    // Load HTML from a string
    $html->load($str);

    //get all category links
    /*foreach($html_base->find('a') as $element) {
        echo "<pre>";
        print_r( $element->href );
        echo "</pre>";
    }*/

    //$html_base->clear();
    //unset($html_base);

    $time1 = $html->find('span[id=row1Time]', 0)->plaintext;
    echo '<span id="time1">'.$time1.'</span> - ';
?>
 
 当我尝试使用以下方法解析HTML中的内容时： 
 
$time1 = $html->find('span[id=row1Time]', 0)->plaintext;
echo '<span id="time1">'.$time1.'</span> - ';
 
 我得到的返回输出来自标签row0-1 with row1Time ： 
 
4:00 PM
 
 我想从带有row1Time的标签row1-1搜索HTML中的内容，以获得包含3:00 PM的返回。 你能帮我用simple_html_dom帮助我获取这些内容吗？ 

There are two different tags in the HTML which are row0-1 and row1-1. I want to search for the contents in the HTML called row1Time from the row1-1 tag.
 
Here's and example HTML:
 
<li class="zc-ssl-pg" id="row0-1" style="">
    <span id="row1Time" class="zc-ssl-pg-time">4:00 PM</span>
    <li class="zc-ssl-pg" id="row1-1" style="">
    <span id="row1Time" class="zc-ssl-pg-time">3:00 PM</span>
 
Here's my PHP:
 
    <?php
    $errmsg_arr = array();
    $errflag = false;
    $link;

    function db_connect()
    {
      define('DB_HOST', 'localhost');
      define('DB_USER', 'myusername');
      define('DB_PASSWORD', 'mypassword');
      define('DB_DATABASE', 'mydbname');

      $errmsg_arr = array();
      $errflag = false;
      $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);

      if(!$link) 
      {
        die('Failed to connect to server: ' . mysql_error());
      }

      $db = mysql_select_db(DB_DATABASE);
      if(!$db) 
      {
        die("Unable to select database");
      }
    }

    $links = $row['links'];
    include ('simple_html_dom.php');
    $html = file_get_html($links);
    //echo $row['links'];

    $base = $row['links'];

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_URL, $base);
    curl_setopt($curl, CURLOPT_REFERER, $base);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    $str = curl_exec($curl);
    curl_close($curl);

    // Create a DOM object
    $html = new simple_html_dom();
    // Load HTML from a string
    $html->load($str);

    //get all category links
    /*foreach($html_base->find('a') as $element) {
        echo "<pre>";
        print_r( $element->href );
        echo "</pre>";
    }*/

    //$html_base->clear();
    //unset($html_base);

    $time1 = $html->find('span[id=row1Time]', 0)->plaintext;
    echo '<span id="time1">'.$time1.'</span> - ';
?>
 
When I tried to parse the contents from the HTML using this:
 
$time1 = $html->find('span[id=row1Time]', 0)->plaintext;
echo '<span id="time1">'.$time1.'</span> - ';
 
The return output I get is from the tags row0-1 with row1Time:
 
4:00 PM
 
I want to search for the contents in the HTML from the tags row1-1 with row1Time to get the return contains 3:00 PM. Can you please help me get those contents using simple_html_dom?
